  • Brain Tumour Detection and Multi Classification Using GNB-Based Machine Learning Architecture   Order a copy of this article
    by Satish N. Gujar, Ashish Gupta, Sanjaykumar P. Pingat, Rashmi Pandey, Atul Kumar, Deepak Gupta, Priya Pise 
    Abstract: Brain tumours are abnormal tissues with rapidly reproducing cells, posing significant challenges for identification and treatment. This study proposes a multimodal approach using machine learning and medical techniques for early diagnosis and segmentation of brain tumours. Noisy magnetic resonance imaging (MRI) are processed with a geometric mean to simplify noise removal. Fuzzy c-means algorithms segment the images, aiding in the detection of specific areas of interest. The grey-level co-occurrence matrix (GLCM) algorithm is used for dimension reduction and feature extraction. Various machine learning techniques, including Convolutional Neural Networks (CNN), Artificial Neural Networks (ANN), Support Vector Machine (SVM), Gaussian Naive Bayes (NB), and Adaptive Boosting, classify the images. Among these methods, Gaussian NB is particularly effective for identifying and classifying brain tumours. This approach leverages advanced AI and neural network techniques to enhance early diagnosis and improve treatment outcomes.

    by Umarani Srikanth, Lijetha C. Jaffrin, Sushmitha Srikanth, Shyam Ramesh 
    Abstract: This paper introduces a hybrid recommender system approach that aims to tackle the problems associated with data sparsity, also referred to as the cold start problem, Recommender systems use user preferences to filter information. To improve recommendation accuracy, our method combines user-based and content-based collaborative filtering techniques. More specifically, content-based filtering takes over when there is little data. When there is a high degree of user similarity, user-based collaborative filtering is used to maximise accuracy by suggesting diverse items. This strategy can be used in a variety of fields, including e-commerce, music, books, and film.

  • Using the BIRCH Algorithm and Affinity Propagation, an Advanced Descriptor for Video Processing   Order a copy of this article
    by Jayanta Mondal, Jitendra Pramanik, Satyajit Pattnaik, Bijay Paikaray 
    Abstract: Video summarisation is the most preferred approach to administer the augmentation of video content. In the area of video surveillance and object and intrusion detection, Video Summarization has been the most popular as it provides concise and less redundant information. As video content continues to expand quickly, an automatic video summary would be helpful for anyone who wants to learn more quickly and with less effort. Most existing methods depend on various network architectures to train a single score predictor for shot rating and selection. This study addresses the issue of video summarisation, which involves selecting significant frames to succinctly and comprehensively express the material of the original film. The current paper presents a comparative study of the application of advanced texture descriptors Local Phase Quantization (LPQ), Local Ternary Pattern (LTP), and Local Binary Pattern (LBP) in the process of Video Summarization. Clusters of key frames have been extracted by unsupervised learning algorithms - Affinity Propagation & BIRCH. The performance of the proposed video summarising method has shown good trial results.

  • Prediction of Success Factors for Mobile Application using Machine Learning Technique   Order a copy of this article
    by Jyoti Deone, Nilima Dongre, Mohammad Atique Junaid 
    Abstract: The remarkable boom in the mobile market has attracted many developers to build mobile apps. However, the majority of developers are suffering to generate earnings. For those developers, knowing the characteristics of successful apps may be very vital. We propose an approach which examines the categories of apps by two factors. First, the correlation is measured between app features and secondly, concepts are extracted from apps to understand the common theme present in them. For this, we selected 3,000 applications available in the Google Play Store. The observations specify that there may be a strong correlation among purchaser rating and the quantity of app downloads, though there may be no correlation between rate and downloads, nor among charge and rating. Moreover, we find standards unique to excessive rated apps and low rated apps. The correlation along with the concepts proves useful for application developers to understand the market trend and customer demand more easily than earlier approaches.

  • Nutritional Cluster Analysis of Leguminous Food Sources Across West Africa   Order a copy of this article
    by Donald D. Atsa'am, Gabriel S. Iorundu, Moses T. Ukeyima 
    Abstract: The present form of the data on West African legumes reported in the West Africa Food Composition Table (WAFCT) do not reflect sub-groupings based on (dis)similarity in nutritive value. A possible consequence is that an uninformed user interested in leguminous food could randomly pick any from the data since all are summarily classified as one family in the WAFCT. To resolve this, the objective of this study was to apply the clustering technique to form sub-groups based on similarity in nutritional content. Three clusters were extracted, and unique properties have been established for food sources in each cluster at the granular level of nutrients. Going by the clustering, users who are interested/not interested in a particular content could look up the cluster with a lower, moderate, or higher content of the desired/non-desired element. The results are useful in the selection of raw materials, formulation of nutritional guidelines, and food labelling.

  • Adaptive Parking Demand Prediction Using Discrete Time Based Dynamic Markov Chain   Order a copy of this article
    by Semeneh H. Bayih, Surafel Tilahun 
    Abstract: The demand for urban parking rapidly increases and becomes a significant traffic issue in densely populated metropolitan regions. Prediction of parking demand is crucial for reducing traffic jams and decreasing greenhouse gas emissions. It is also essential to the development of parking facilities and price adjustments in urban parking planning. Most of the earlier studies developed model for parking demand prediction using historical data which lack to update the demand data. Furthermore, the demand predictions are not considering the effect of parking pricing. However, parking pricing affects the demand in a given parking platform. To address this issue, we have considered three categories of parking demand based on price based preference. Dynamic non-homogeneous Markov chain with discrete time and discrete state is used to predict the parking demand. An adaptive approach or a learning approach is proposed to make the Markov chain dynamic and to adapt changes in the demand environment. A numerical example demonstrating the prediction from data collection as well as incorporating the adaptive strategy so that the system learning new changes, is presented.

    by Samira Hazmoune, Fateh Bougamouza 
    Abstract: Sentiment analysis (SA) is an important natural language processing (NLP) field that involves extracting sentiments and opinions from text data. Although SA has advanced significantly, its application to dialectal Arabic text presents challenges due to linguistic nuances and resource constraints. This research investigates the incorporation of emojis into SA for Algerian Arabic dialect (AAD), marking the first exploration of its kind in this area. Specifically, we focus on emoji translation, building upon prior studies highlighting emojis, potential in SA and their translation into meaningful words or sentences as a preprocessing approach. We evaluate the impact of this approach on enhancing sentiment classification in AAD text, specifically focusing on customer reviews of Algerian telephone operators. After preprocessing, including various emoji translation techniques, we employ transfer learning by fine-tuning DziriBERT model on a compiled Algerian dialect dataset. Our results demonstrate promising outcomes and offer novel conclusions and perspectives in AAD sentiment analysis.

    Abstract: Millet crops play a crucial role in global food security, providing sustenance to millions of people worldwide. Mildew disease poses a significant threat to pearl millet, a staple crop in many regions, impacting both its quality and yield. Detecting diseases in millet crops is crucial for maintaining both the quality and quantity of agricultural yields. However, limited labelled data and the expense of manual data labelling pose significant challenges in this domain. To address these issues, we suggest a deep learning ensemble framework that utilises the potential of multiple models for enhanced disease detection accuracy. Ensembles integrate the strengths of individual deep-learning models to improve overall performance and robustness. DenseNet121 and ResNet50, two deep learning models, were selected as the base models in our ensemble. Preliminary experimental results demonstrate the effectiveness of our ensemble approach, with an impressive accuracy of 96.6%.

  • Comparing Discrimination and Calibration Performance of Two Flexible Link Functions in Discrete Survival Models   Order a copy of this article
    by Susan Maposa, Alphonce Bere, Caston Sigauke, Charles Chimedza 
    Abstract: This study provides the first direct comparison between the Pareto and Logit-power link functions within discrete survival models, evaluated alongside three commonly used links. We assess their discrimination and calibration using simulated and real-life datasets with varying skewness. Simulations included 100 data sets with symmetric, right-skewed, and left-skewed distributions, and bootstrapping was applied for robust evaluation. The results show that cloglog excels in discrimination, while logit offers superior calibration. The Pareto family demonstrates robust performance, making it a reliable secondary option. However, Logit-power performs poorly in calibration and is unsuitable for discrete survival models. The study offers practical recommendations for implementing the Logit-power link, addressing its complex estimation process, and suggests a grid search approach using information criteria for parameter optimization. These findings highlight the importance of carefully selecting link functions in discrete survival modeling.
