  • Robust Computational Modeling of the Sodium Adsorption Ratio Using Regression Analysis and Support Vector Machine   Order a copy of this article
    by Alireza Rostami, Milad Arabloo, Alibakhsh Kasaeian, Khalil Shahbazi 
    Abstract: In present study, two new methods including least-square support vector machine (LSSVM) and regression-based model, were created for accurate estimation of the adsorption ratio of sodium in terms of ionic concentrations of calcium (Ca2+), magnesium (Mg2+), and sodium (Na+); the bicarbonate (HCO3-) to Ca2+ ratio; and salinity/conductivity of the used water so as to explain the impact of water quality on the irrigation water using a reliable literature database. The results of the developed models were compared with a commonly used model in literature using visual and statistical parameters. Consequently, the supremacy of the regression-based approach is demonstrated with the average absolute relative deviations (AARDs) of 0.06% for HCO3-/Ca2+ ratio?1 and 0.28% for HCO3-/Ca2+ ratio>1. Finally, it should be mentioned that the proposed methods are easy-to-apply and sufficiently accurate which require the less calculations leading to the rapid estimation of sodium adsorption ratio in wide range of operational conditions.

  • Hierarchical non-Archimedean DEA models: Application on mobile money agents locations in the city of Harare   Order a copy of this article
    by Jacob Muvingi, Arshad Ahmud Iqbal Peer, Farhad Hosseinzadeh Lotfi 
    Abstract: Hierarchical non-Archimedean data envelopment analysis (DEA)rnmodels are proposed to evaluate the efficiency of two types decision making units (DMUs) which are integrated. The determination of non-Archimedean values was extended to cater for decision-making units (DMUs) with a hierarchical group structure. The proposed approach was applied in the location analysis of mobile money agents locations. In a bid to improve adjusted efficiency ratings of groups with unequal size, an adjustment value on selected groups average efficiency ratings was determined through the identification of ideal location groups proxies. Three district location efficiency ratings (DLER-1, DLER-2, and DLER-3), were respectively generated through the non-Archimedean DEA hierarchical method, the DEA hierarchical method where the non-Archimedean epsilon is ignored, and the treatment of district locations as a system made-up of suburb locations. The application of the non-Archimedean value on district locations efficiency analysis reduced the number of efficient district locations.

  • Reducing Feature Selection Bias Using a Model Independent Performance Measure   Order a copy of this article
    by Weizeng Ni, Nuo Xu, Honghao Dai, Samuel Huang 
    Abstract: Feature selection is an important step in the process of learning from data, especially when dealing with dataset with small sample size and high dimensionality. A popular approach for feature selection is the so called wrapper approach. In recent years, researchers have realized that wrappers have a feature selection bias due to data overfitting. External cross-validation or dual-loop cross-validation has been proposed to solve this problem. However, cross-validation approaches tend to bring in excessive variability for small sample size data with high dimensionality. This paper shows that a model-independent approach for feature selection; namely, minimum expected cost of misclassification (MECM), can reduce feature selection bias without the need of cross-validation. A designed experiment was conducted using a synthetic dataset. The results show that 10-fold dual-loop cross-validation based wrapper feature selection has around 33% higher error rate than the noise-free error rate and fails to identify discriminative features consistently in all 10 folds. On the other hand, MECM can select more discriminative features than dual-loop cross-validation and shows more robustness to different classification models than wrapper-based approach. A real-word colon cancer dataset is further used to demonstrate the effectiveness of MEMC.

  • Supervised Local Community Detection Algorithm   Order a copy of this article
    by Ali Choumane, Abbass Al-Akhrass 
    Abstract: Community detection aims to partition a network into internally densely connected groups of nodes. In huge networks, exploring the whole network as done in global community detection algorithms is computationally very expensive. Moreover, for applications such as antiterrorism, the spread of disease on networks and viral advertising, researchers are now more interested to find the community surrounding one or a few individuals. In this context, we propose a new local community detection algorithm that starts from a seed node and iteratively expands it to reach the community that resembles the most to a real-life community. The expansion process is controlled by a neural network classifier that decides which nodes to add to the community being expanded. To build this classifier, we propose three measures that allow quantifying nodes relationship strengths to their communities. We train our model using the well-known LFR benchmark networks. It is built in a way to be used on any new network without the need to train it again. Experiments achieved on both, an extensive set of LFR datasets and existing real-world networks from different application domains, proved the high performance of our method as compared to the baselines.

    by Maha Alotaibi 
    Abstract: Nowadays, there are numerous catastrophic events, which affect a large number of people in the world including crises, fires, floods, road accidents, earthquakes, and terrorist attacks. The majority of public people use mobile and internet all day long. From the literature review, we found that the coordination between agencies in emergency responses is not satisfactory. Different emergency organizations should share different types of resources such as information, equipment, vehicles, etc. For that reason, the emergency response teams need to use an effective coordination framework to mitigate the results of any emergencies such as loss of life. Under these circumstances, respondents, emergency services, and volunteers work hard to communicate and divide resources among themselves. The purpose of this paper is to investigate the coordination in emergency response with mobile techniques, by developing a flexible and dynamic mobile platform which offers tracking mechanism and information management.
