Thesis Title: Social Group Optimization: Analysis, Modifications and Applications

In this work, stability analysis of social group optimization (SGO) has been performed through Von Neumann technique which ensures the convergence of SGO, theoretically as well as experimentally, within a range of values of the different parameters. Further, some suitable modifications have been performed to make SGO applicable to different domains. Also these modified algorithms have been applied to some niche areas and to some popular problems, in which a competitive performance of these variants of SGO, have been observed.

In this paper, we have reviewed some of the inertia weight strategies and applied them to Social Group Optimization (SGO) to study the changes in its performance and have performed a thorough analysis on the same. Following the analysis, the need of a more generalized inertia weight strategy was felt which could be used in parameter tuning for different variety of problems and hence Sigmoid adaptive inertia weight have been proposed. SGO with sigmoid-adaptive inertia weight (SGOSAIW) has been simulated on twenty-seven benchmark functions suite and further simulated on few mechanical and chemical engineering problems.

Getting immediate and appropriate care for the victims of Road Traffic Accidents (RTAs) in countries like India with huge population is a challenging job. In this paper a new hybridized evolutionary algorithm has been proposed for hyper-parameter tuning of the hyper-parameters of the prediction models using which mortality prediction of victims of RTAs in India have been made. The proposed methodology Opp-SGO-DE has been used for parameter tuning in prediction algorithms like Random Forest  and Support Vector Machine  and promising results were found from the experimentation.

IoT gadgets installed in smart homes ease human life and they can be controlled from remote locations. These gadgets generate different categories of data from various sensors. Sometimes immediate data processing is required to provide a quick response to the smart home applications. Edge nodes dwell at the edges of IoT gadgets for faster processing of data. In this paper, we have used a rule-based classifier that categorizes generated data from sensors and allocates edge nodes for the near real-time data processing. Finally, we assess the performance of proposed classifier with other approaches.

This study aims to see how well machine learning models are suitable for the prediction of fetal health using CTG data. The Classification algorithms that have been used to get the lowest prediction error are Logistic Regression, KNN, Random Forest, and Gradient Boosting Machine (GBM). The performance of each model was evaluated in terms of accuracy, precision, recall, and F1-score. It has been observed that Random Forest has the highest accuracy of 0.99.

Perceptual watermarking approaches achieve better image fidelity with the advantages of the Human Visual System. Saliency uses the advantages of this feature by identifying different visually perceptual regions of an image. Additionally, Phase congruency exploits those features of digital images by detecting the corner points. In the proposed method, the information hiding capacity is generated from both bit depth maps created by comparing phase congruency results and saliency outcomes of an image that ascertains the low perceptually visible pixels (utilizing the Least Significant Bit technique).
