A Distributed Integration System Enabling Electronic Health Records: An Italian Experience
by Cinzia Muriana, Giulio Gilia, Vincenzo Mistretta, Tommaso Piazza, Giovan Battista Vizzini
Abstract: Today distributed systems are commonly employed in patient data
management to improve the care process. Moreover, distributed systems can be
usefully applied to realise lean and flexible architectures that facilitate health
care structure interoperability. Systems used in health care structures are
characterised by proprietary data flow formats and encoding systems, which
hinder the possibility of sharing data in a standard format, and extracting
atomic data for further analysis. This paper describes the architecture of a distributed interoperability system able to structure flow data into standard
formats and send them to an advanced electronic health record designed as part
of the Smart Health 2.0 project (PON04a2_C). The use of the distributed
interoperability system within the experimental phase of the electronic health
record highlights the flexibility of the proposed solution in meeting the reality
of the health care structures involved.

A Novel Patient Friendly IT Enabled Framework for Selection of Desired Health Care Provider
by Salaja Silas, Elijah Blessing Rajsingh
Abstract: The healthcare providers have tremendously grown during the past decade. Selecting a healthcare provider based on patients preference is really a great challenge. The purpose of this paper is to provide an IT enabled framework that will help the patients to find a suitable healthcare provider based on their preferences. The patients preferences in selecting a healthcare provider differ based on their geographical region, gender, age and socio-economic background. Discovering a set of feasible healthcare providers and selecting the most appropriate healthcare provider based on the patient preferences can be modeled as a multi-criteria decision making problem. In this article, a novel patient friendly framework is proposed for selecting the best healthcare provider. Even with a huge data set, the results show that the proposed framework is robust, reliable, faster and effective. The analysis reveals that the number of preferences and the healthcare providers influence the healthcare selection time. Case studies on 500 patients from different geographical regions reveal that the proposed framework is effective.

Real-Time Signal Processing of Photoplethysmographic (PPG) Signals to Estimate the On-Demand and Continuous Heart Rate by spectral Analysis
by Madhan Mohan, Nagarajan V, Vignesh J.C
Abstract: In Healthcare applications, heart rate is one of the vital signs which give the health informatics of a person and also it is an important parameter to monitor for athletes and fitness enthusiasts during their workouts. In earlier days, the Heart Rate monitoring devices like ECG are very expensive and required more hardware resources. But nowadays, the evolution of PPG sensors help to develop low cost Heart Rate monitoring devices with minimal hardware resources. PPG sensor based Heart rate monitoring devices are non-invasive low cost devices and it can be used in real time applications to estimate the heart rate of a subject. In this paper, an efficient algorithm is proposed to find the Heart rate using frequency spectrum analysis on PPG signals. The proposed algorithm uses minimum hardware so it can be targeted in real time embedded platforms. Using the proposed algorithm, the Heart rate is calculated with a pass percentage of 99.2, Mean Absolute Percentage Error (MAPE) of 1.59%, Mean Absolute Error (MAE) of 1.20 BPM and Reference Closeness Factor(RCF) of 0.989. The First reliable Heart rate output from the algorithm comes in 6.5th second, which is the minimum possible time. The algorithm operates with a speed of 2 MIPS and with a memory of 18 KB. So the proposed method can be integrated to any low cost real-time embedded platforms to accurately measure the Heart Rate.

Automatic Ostia Detection in CTA Volume Data: A Comparative Study
by Noha Seada, Mostafa G.M. Mostafa
Abstract: Objectives: Automatic coronaries ostia detection is implemented using two different methodologies: Template Matching and Corner Detection. Methods/Analysis: The proposed methods used for the ostia detection are selected for implementation after studying ostia anatomical features and observing their appearance on a segmented ascending aorta contour. Findings: Template matching is implemented for coronaries ostia detection, since they have a special pattern on a segmented ascending aorta contour. Therefore two templates are identified, one for the right and one for the left coronaries ostia. These two templates are matched across the input volume to detect the coronaries ostia. For corner detection; Harris corner is implemented to detect coronaries ostia as corners appearing on the ascending aorta. It is applied on the volume to detect corners and ostia points are correctly located based on ostia anatomical features that automatically identifies the ostia points. Novelty/Improvement: The two methods used for automatic ostia detection succeeded to detect the coronaries ostia points in all test cases and results are validated versus a ground truth. Although both approaches succeeded in ostia detection; the template matching accuracy and processing time are better than that of the Harris corner detection. Moreover, the two methodologies presented for comparison; give competitive accuracy and processing time with respect to other previous work for ostia detection and this proves the correctness and efficiency of the methodologies.
Keywords: Template Matching; Automatic Ostia Detection; Computed Tomography Angiography (CTA).
Learn Quest A Virtual Reality based system for training Autistic Kids
by Shriram K Vasudevan, Abhishek S N, Swathi S, Akshaya Lakshmi, Anandram S
Abstract: Childhood is the best part of life. A child enjoys anything and everything in this world without any discriminations. It is also the period of rapid brain development, where the kids learn the stepping stones for life. Autism Spectrum Disorder (ASD) is a group of developmental disabilities that causes major impairments in social, communication and behavioral aspects of the children. Unlike other children, an autistic kid finds it difficult to go along and communicate with others. Social interactions and communication are the major aspects for peaceful living of any human being, and these children face difficulties in the same. So, we have developed a virtual reality based game engine that would attract the children and make them enjoy interacting with it while increasing the chance for learning. As the children continues playing this game, their learning and interacting ability increases nullifying some effects of autism, thus making it a boon for these kids.

Optimized DBN for Effective Enhancement of Ultrasound Images with pelvic Lesions
by Sandanand L. Shelgaonkar, Anil B. Nandgaonkar
Abstract: Nowadays, the ultrasound modality is the current research areas for lesion analysis. Moreover, it is renowned; the ultrasound images exhibit hassle- free utilization as well as cost effectiveness. In the literature, merely a small number of reliable contributions have been reported from the females for analyzing the pelvic lesions. However, the literature lags with adopting a prominent enhancement procedure to facilitate the diagnosis process. This paper adopts an Optimized Deep Belief Neural (ODBN) network for enhancing the US image of pelvic portions. It considers the higher order as well as lower order statistical characteristics of the image to define the appropriate filter band for image enhancement. The lower order features are optimized to use with the higher order features so that the optimal usage of features is reported here. To optimize the lower order features, an advanced optimization search algorithm named Grey Wolf Optimizer algorithm (GWO) is exploited. The ODBN learns the optimized features and the noise characteristics for precise prediction of the filter bands, which enhance the image substantially over the conventional filter bands. The performance of the proposed method is compared with the conventional methods using the benchmark as well as real-time US images of pelvic lesions. The quality of enhancement is ensured using the renowned measures such as PSNR and ESSIM that exhibit the performance of the proposed approach.

An innovative technical solution to avoid Insomnia and Noise-Induced Hearing Loss
by Shriram K V, Ikram Shah, Sriharsha Patallapalli, Karthikeyan S, S. Subhash Chandran, U. Adithya Bharadwaj
Abstract: The major challenge these days with the increased usage of the mobile phone is loss of sleep (insomnia), increased stress and finally more damages to the health and mental wellness. Most of us have the habit of even keeping the phone underneath the pillow while sleeping. There are people who are now treated for mobile addiction. People are there to use a phone to get sleep sooner. Sleep time is meant for the brain to rejuvenate, organize thoughts and relax. If the sleep patterns are disturbed due to a continuous external commotion, it will result in the subconscious to spend energy and brain space. Hence, it is wise to switch off the music after the person sleeps which most of us do not do as we are already slept by then. Also, wearing headphones for an hour will increase the bacteria in your ears by 700 times. Many researches in the past prove that music is a solution to reduce stress and to bring sleep. But, we, the users are using headphones for music and it causes some dangerous side effects including affecting the sleep and noise-induced hearing loss. There is a strong need to avoid unnecessary health problems which are meant to be avoided. Here, we propose a system which will ensure that the music player is stopped after understanding that the person using it has slept and he no more needs the tunes thereby not disturbing the deep sleep and preventing insomnia and noise-induced hearing loss. Novelty is what we present in this research through making sure if the person has really slept or not. Our innovative system switches off the audio automatically when a person falls asleep. The same can be expanded and improvised to provide analytics to the user as in how many hours did he sleep peacefully, how is his body tuned towards listening to music, how long does he need music, under what conditions does he over listen or under listen etc.

Spectro-Temporal Analysis of Electromyogram Signals (EMGs)
by Meziani Fadia, Rerbal Souhila, Debbal Sidi Mohammed El Amine
Abstract: Electromyography (EMG) signals can be used for clinical/biomedical applications. Is a very important biomedical signal that measures electrical currents generated in muscles during its contraction representing neuromuscular. Individual muscle fiber action potentials are sometimes acquired using wire or needle electrodes placed directly in the muscle. The combination of the muscle fiber action potentials from all the muscle fibers of a single motor unit is the motor unit action potential (MUAP) which can be detected by a skin surface electrode (non-invasive) located near this field, or by a needle electrode (invasive) inserted in the muscle. The simple detection with electrodes has been recognized for a long time as an important tool for the diagnosis of neuromuscular diseases, although its accuracy is still insufficient to diagnose some neuromuscular diseases (Myopathy and Neuropathy). It does not enable the analyst to obtain both qualitative and quantitative characteristics of the EMG signals. The efficiency of diagnosis can be improved considerably by using modern digital signal processing techniques. Therefore, these last can provide useful and valuable information on these signals. The aim of this study is to analyse EMGs signals using temporal and frequency analysis. This analysis is based on temporal parameters such as :amplitude, energy, entropy... and frequency parameter such as median frequency and mean frequency by using the FFT and the non-linear information by using the bispectrum analysis , can provide a wide range of informations related to the type of signal (normal and pathological).

Generating a stable primary schedule for an integrated surgical suite
by Asie Soudi, Mehdi Heydari
Abstract: Efficient utilization of operating room (OR) is a common anxiety of surgical suit manager which necessitate an effective planning and scheduling of surgeries. In this paper we investigate predictive / reactive scheduling of an integrated surgical suite in the form of a two-stage hybrid flow shop scheduling problem (HFSP). The deterministic model comprises both assignment and sequencing decisions for elective surgeries. By further considering shared capacity between elective and emergency patients, a chance constrained programming model is extended for the first time to cope with uncertain disruption. It is shown that how a chance constrained model will reduce to just considering an augmented surgery which processing time depends on distribution function of emergency surgery processing time and confidence level of scheduler. Two new important measures in reactive scheduling literature, 'stability' and 'robustness' are taking into account in surgical suite scheduling for the first time. Computational results demonstrate the efficiency of primary schedule generated by extended chance constrained programming model as well as the effectiveness of new measures in hospitals. As the chance constrained model is NP-hard, a decomposition heuristic algorithm based on tabu search (TS) is proposed to cope with problems of real size.
Keywords: Stability and robustness; predictive / reactive scheduling; hybrid flow shop; integrated surgical suite.
Adaptive Improved Binary PSO Based Learnable Bayesian Classifier for Dimensionality Reduced Microarray Data
by Barnali Sahu, Satchidananda Dehuri, Alok Jagadev
Abstract: This article presents, an adaptive improved binary particle swarm optimization based learnable Bayesian classifier for dimensionally reduced microarray data. In the first fold of this two-folded work, the problem of dimension is reduced by unsupervised method of feature reduction. We apply k-means clustering algorithm on the microarray data to group functionally redundant genes followed by application of signal-to-noise-ratio ranking technique to generate an intermediate feature subset consisting of most relevant and non-redundant feature subsets. In the second fold, the feature subset has been given to adaptive binary particle swarm optimization based learnable Bayesian classifier for simultaneous selection of features and classification. We conduct an extensive experimental work on a few benchmark datasets to validate its classification accuracy with and without reducing the dimensionality of micro-array data. It was observed that our method is not only accepted as a good classifier over methods, which are considered here for comparison but also be treated as an alternative method of reducing dimension of the problem.

Product Unit Neural Network trained by an Evolutionary Algorithm for diabetes disease diagnosis
by Radhwane BENALI, Nabil Dib, Fethi Bereksi Reguig
Abstract: Diabetes disease occurs when the level of glucose in the blood becomes higher than normal because the body is unable to produce the insulin which is needed to regulate glucose. In this study, a new classification method for the diagnosis of diabetes disease was developed. This method is based on a special class of neural network known as product-unit neural networks (PUNN) which was trained by an evolutionary algorithm (EA). We have used EA in order to determine the basic topology of the structure of the PUNN, and to estimate its coefficients weights. The performances of the proposed classifier were evaluated through the sensitivity, the specificity and the classification accuracy using both conventional and 10-fold cross-validation method using the Pima Indian Diabetes (PID) dataset. Obtained results reveal that the proposed approach outperforms several famous and recent methods existing in the literature for diabetes disease diagnosis.

Development of a Serious Game to Enhance Assistive Rehabilitation
by Mauro Bellone, Andrea Martini, Francesco Argese, Piero Cirillo, Italo Spada, Antonio Cerasa
Abstract: The aim of this study is to investigate novel assistive technologies
based on serious gaming for the assessment of postural control and motor
rehabilitation. Previous research already demonstrated that rehabilitation and
physical activities can improve the quality of life of patients, and virtual reality
applications may act as good additional companions during the therapeutic
sessions. Indeed, workout routines supported by serious gaming encourage
patients to train harder, bringing the therapy towards a pleasant game into a
virtual environment. During the game, sensors track the movements of the
players and transfer the data to software components that record a database
from which patients progress can be determined. The acquired measures are
interpreted in the form of new biomarkers, which enable the assessment of
postural control. Such biomarkers are based on a probabilistic approach and
show the capability to discriminate between well-performed exercises and incorrect movements. A long-term experimentation on a specific exercise is
proposed, showing a considerable improvement, ranging from 5\% to 30\%, in
the performance of patients.

An Innovative Solution for prevention of reverse flow of blood in IV set (Intravenous set) using Embedded Systems
by Abhishek SN, Ikram Shah, K.V. Shriram
Abstract: The demand for medicine and doctors is never ending and it is really evergreen as our society has been revolutionized and the life expectancy rate has increased. Everyone starting from a six year old child to 90 year old veteran is aware of all kind of diseases exists as of now, specialization of doctors, which doctor to approach when we have a particular problem and so on. Thus, a common wish prevailing in everyone irrespective of age is that to live long and stay in pink of health. Adding to this point, millions and millions of innovations are being made in the medicinal field every decade to enhance the average life expectancy rate. There are various sectors of engineering that are involved in creating and/or maintaining various medical instruments. Say, from the smallest equipment like syringe to the largest one like CT scan machine have major contributions from the engineering sectors. IV Set (Intravenous set) is one among those substantial inventions in the medicinal field; it is actually used for transferring blood or saline from the IV/fluid bag to the patients body at a speed and pressure that the human body can accept. There is a notable threat associated with using the IV set which most of the doctors and care takers are aware of; When the fluid in the IV bag runs out (gets emptied) the patients blood would start flowing through the IV tube in the reverse direction towards the empty IV bag as the pressure of blood in the human body is more than the pressure experienced by the empty IV bag (diffusion), thus leading to blood loss and pain, at times. Thus the caretakers must be vigilant enough to replace the fluid bag at an appropriate time to avoid blood loss. The innovation proposed here is a solution that would prevent such blood losses and doesnt require manual monitoring of the IV bag thereby stopping the reverse blood flow well in time. This not only prevents blood loss but also reduces the stress for the care takers and pain for the patients. The product is tested and is costing less than 100 USD and is one-time investment for the hospitals.

An inventive and innovative system to detect fall of old aged persons A novel attempt with IoT, Sensors and Data Analytics to prevent the post-fall effects.
by Juluru Anudeep, Gudimetla Kowshik, Popuri Vamsi Krishna, Ikram Shah, K.V. Shriram
Abstract: According to the statistics of NCOA (National Council on Aging) these days rate of deaths in the old aged people has reached a critical state that for every 11 seconds an older adult is being treated for a fall and for every 19 minutes a death is taking place. Most of the old aged people are suffering from the back pain, joint pain, knee pain and they mostly are the ones who arent able to walk properly and are mostly constrained to bed. Statistics by north eastern Ohio state reveals that, the rate of emergency room treatment of fall-related injuries in persons aged 75 and older approached 80 per 1,000 per year in women and 60 per 1,000 per year in men. Falls are indications to some critical problems like immobility, fragility of bones and chronic health impairment. Falls in elders vary from that of the falls in kids, as the healing power in the old people slackens with their age. Falls are going to play a crucial role in the health line of the old people. Due to the falls there will even be a huge impact on the heart. Old people with heart diseases when falls suddenly, there is risk of being affected by Tachyarrhythmia which is typically a heart disorder in which the heartbeat raises to an abnormal rate of more than 100 beats per minute which is approximal to an cardiac arrest. So, in order to reduce these type of risks in elderly people , We present a frugal and affordable system that could monitor the motion of the old people and can detect their fall. Detection is not done before the fall or when person remains in rest state, it detects immediately after fall and alerts the concerned persons to do the necessary action to save the person. We use IoT, Sensors and Data analytics to build this system. The system is tested for its functioning and is fool proof.

Transmission and Archiving of Reduced MRI Medical Images
by Hedi AMRI, Med Karim ABDMOULEH, Ali KHALFALLAH, Jean-Christophe LAPAYRE, Med Salim BOUHLEL
Abstract: Medical images are often large. To minimize their file sizes, different compression standards like JPEG, JPEG 2000 and TIFF have been developed, but they can affect the image quality in case of lossy compression. In this paper, we propose a compression method based on image resizing that can reduce the file size to a quarter before its transmission or archiving. When it is received or before its display, the reduced image is enlarged to ensure better visual comfort. This approach is called REPro. In this context, we have used three image reduction techniques namely Square-Square Mesh Decimation, Square-Square filtered Mesh Decimation, the Square-Staggered-Square filtered Mesh Decimation. In addition, we have utilized four enlargement techniques namely Zero padding, Nearest Neighbor interpolation, Cubic Spline interpolation and B-interpolation to resize MRI images. The experimental results prove that the combination of the Square-Square Mesh Decimation with the B-Spline interpolation ensures the minimum distortion of the original image.

Radial Basis Function Neural Network with Genetic Algorithm for Discrimination of Recombination Hotspots in Saccharomyces Cerevisiae
by Ashok Dwivedi
Abstract: Recombination influences the evolution of Saccharomyces Cerevisiae. Genomic regions where
recombinations occurs are known as recombination hotspots. There are two kind of hotspots for recombination. The spots where recombination occurs more frequently are called recombination hot spots and regions where recombination occurs less frequently are known as cold spots. In this work, we have formulated methods based on neural network models for the classification of these hot and cold recombination spots on the basis of compositional features of nucleotide sequences. These models were validated using tenfold cross validation technique. The classification accuracy of 83%, 82%, and 78 % were achieved using radial basis function neural network with genetic algorithm, radial basis function neural network and multilayer perceptorn models respectively. Moreover, the performance of these model were evaluated on differenct classification measurements. Furthermore, results indicate that redial basis function neural network with genetic algorithm gives best result.

Analysis of salivary components as non-invasive biomarkers for monitoring chronic kidney disease
by Navaneeth Bhaskar, Suchetha M
Abstract: Saliva, a valuable source of biochemical information, is a potential diagnostic substance that helps to identify many diseases. Studies have revealed that saliva tests help identify many diseases. Saliva test has excellent advantages over blood test as the former can be collected non-invasively using simple equipment. This paper explores how salivary components can be used as diagnostic tool to identify chronic kidney disease (CKD). Experimental analysis was conducted to assess the levels of salivary components in whole saliva of CKD patients in contrast with healthy people. Urea and creatinine are the most accepted biomarkers of CKD. The correlation between creatinine and urea levels in human saliva and blood were analyzed. Unstimulated saliva flow rate and pH levels were also monitored in this study. The results obtained from this study give concrete evidence that there is a positive correlation between creatinine and urea levels in blood and saliva. From the derived regression line equations, serum urea and creatinine values can be predicted from salivary values. Receiver operating characteristics (ROC) performance analysis was performed and area under the curve (AUC) of 0.95 and 0.89 was obtained for salivary creatinine and urea.

by J. Saraswathy, M. Hariharan, Wan Khairunizam, J. Sarojini, Sazali Yaacob
Abstract: This paper proposes a new investigation of time-frequency (t-f) based signal processing technique using wavelet packet spectrum (wpspectrum) for classification of newborn cry signals. T-f approaches can analyze the non stationary signals comprehensively in joint t-f domain compared to the time or frequency domain techniques. This study was initialized with the extraction of a cluster of t-f features from the generated t-f matrix of recorded cry signals using wpspectrum by extending time-domain and frequency-domain features to the joint (t-f) domain. In accordance, conventional features such as Mel-frequency cepstral coefficients (MFCCs) and Linear prediction coefficients (LPCs) were also extracted in order to compare the performance of the suggested t-f approach. Probabilistic neural network (PNN) and general regression neural network (GRNN) were used to evaluate the efficacy of the extracted feature vectors. The proposed methodology was implemented to classify different sets of infant cry signals cry including binary and multiclass problems. Best empirical result of above 99 % was reported and revealed the good potential of t-f methods in context of infant cry classification.

Breast abnormality based early diagnosis of breast cancer using non-invasive digital infrared thermal imaging
by Priya Tushar Hankare
Abstract: Breast cancer is one of the most leading and common cause of cancer. It can be detected by infrared thermal imaging Technique by observing the temperature distribution on the breast. Breast thermography is considered as a valuable tool for early breast tumours detection. The fast growing tumour has a higher metabolic rate and associated increase in local vascularisation. It will cause the occurrence of some asymmetric heat patterns. Clinical interpretation of a breast thermogram can be done on the asymmetry analysis of the heat patterns visually and subjectively. In this paper, a new approach for early detection of breast cancer is proposed using asymmetry analysis of breast thermograms. The heat patterns are segmented and the asymmetry analysis is performed by using histogram generation and feature extraction. Extracted statical features clearly indicate the abnormality of a breast thermogram.

by Deepthi K. Prasad, L. Vibha, K.R. Venugopal
Abstract: Diabetic macular edema (DME) is a consequence of diabetic retinopathy characterised by the abnormal accumulation of fluid and protein deposit in the macula region of the retina. Prior disclosure of even a trivial trace of DME is essential as it could consequently lead to blurred vision. DME can be diagnosed by the presence of exudates (glossy lesions) in the retinal fundus images. In this work, OD and macula are detected using morphological operation and hard exudates are segmented. Exudates are classified using early treatment diabetic retinopathy standard as normal, moderate or severe cases. The proposed work also incorporates the extraction of various features from the retinal fundus image. Various textural and exudate features are extracted and fed to a classifier to detect DME. Experiments are performed on a publically available database. Performance is evaluated with metrics like accuracy, sensitivity, specificity and accuracy. The results obtained are promising.
Keywords: diabetic macular edema; DME; macula; optic disc; hard exudates; feature extraction; classification; random forest.

by Bayu Adhi Tama, Kyung-Hyune Rhee
Abstract: Lifestyle-driven disease such as diabetes mellitus has become a serious health problem worldwide. We propose the fusion of neural network-based classifiers, i.e., neural network and support vector machine to assist in early detection of diabetes mellitus. These classifiers are combined to produce the final prediction. However, when considering a number of classifiers in the pool, the selection of combination rule is not easy to understand. The aim of this paper is to investigate the performance of different combination rules, including several single classifiers involved in the ensemble. We use various performance metrics and validation tests to assess the performance of these classifiers using a real-world dataset. Finally, among the classifiers we evaluate their performance differences using statistical significant test. The experimental results indicate that combination rule with average voting scheme is the best performer compared with other combination rules and single classifiers in the ensemble.

by Bolaji Efosa Odigie, Peter Uwadiegwu Achukwu, Moses Eromosele Bello
Abstract: This study proposed a neuro-fuzzy model for cervical lesions (CL) detection in commercial sex workers. Our aim is to formulate an understandable and practicable model for CL screening of commercial sex workers (CSWs) operating in rural communities in Edo State, Nigeria. The specific objective is to confirm the levels of precision of the neuro-fuzzy model using liquid-based cytology (LBC) method. The adaptive neuro-fuzzy inference system (ANFIS) implementation was used for screening and LBC techniques for confirmation of the ANFIS outcomes. The classification performance of ANFIS model had 98.7% precision with a training error of 1.1652 and basic testing error 1.255. LBC showed eight cases of CL (15.4%) from 259 prostitutes and was age and duration of commercial sex-dependent (P < 0.05). The present ANFIS implemented model is excellent for routine screening of the CSWs, while LBC remains a gold standard for CL diagnosis worldwide.

QUERY OPTIMIZATION WITH WEIGHTED FISH SCHOOL SEARCH IN ONTOLOGICAL DATABASE WITH APPLICATION OF BOINFORMATICS
by Jaya Raju
Abstract: Making queries from large ontological database has a severe problem of generating query plans as it is made in form of left tree search form. This restricts the querying for composite applications and speed of acquiring query results. In such a scenario the most prominent approach is to optimize the indexing of graph nodes in ontological database and many evolutionary and particle of swarm optimization (PSO) based approach had already been attempted. However, loss of diversity and unanticipated convergence causes the solution to remain sub-optimal. In this study we present a weighted fish school searching based query optimization technique owing to its scalability and self control functioning with the application of bioinformatics. It creates probabilistic logic based weight system for the fish school search in a hierarchical tree form which results in increased accuracy when put in comparison with standard PSO based methods and its other variants

Abstract: Machine learning techniques for cancer prognosis are being widely researched and applied. Supervised learning in conjunction with other computational techniques are paving the way forward for predictive health analytics. The step of input feature processing is very important in order to obtain meaningful results from a data analytics problem. In this paper, the Extended Kalman Filter (EKF) and Fuzzy K-Means clustering algorithms have been combined and a hybrid algorithm is proposed with improved functionality compared to either of the two separately. The proposed hybrid algorithm implements a fuzzy K-means algorithm with Support Vector Machine (SVM)coupled with an EKF for data filtering. From the filtering and prediction consecutive cycles, the result of Kalman filters is obtained and fuzzy membership functions are calculated in order to form a relationship between the labels and attributes. K-means utilizes this relationship to create a new modified set of attributes, which are given to the SVM classifier, with lesser number of support vectors. The number of clusters is added into the training process as the input parameter except the kernel parameters and the SVM penalty factor. The approach was tested for various publicly available data sets like UCL,SEER and a real data set compiled by the authors. After performing statistical analysis, the accuracy, precision, recall and F-score value of the algorithm have been found and compared against those obtained from the traditional algorithms.
