Big Data Analytics with OENN Based Clinical Decision Support System

In recent times, big data analytics using Machine Learning (ML) possesses several merits for assimilation and validation of massive quantity of complicated healthcare data. ML models are found to be scalable and flexible over conventional statistical tools, which makes them suitable for risk stratification, diagnosis, classification and survival prediction. In spite of these benefits, the utilization of ML in healthcare sector faces challenges which necessitate massive training data, data preprocessing, model training and parameter optimization based on the clinical problem. To resolve these issues, this paper presents new Big Data Analytics with Optimal Elman Neural network (BDA-OENN) for clinical decision support system. The focus of the BDA-OENN model is to design a diagnostic tool for Autism Spectral Disorder (ASD), which is a neurological illness related to communication, social skills and repetitive behaviors. The presented BDA-OENN model involves different stages of operations such as data preprocessing, synthetic data generation, classification and parameter optimization. For the generation of synthetic data, Synthetic Minority Over-sampling Technique (SMOTE) is used. Hadoop Ecosystem tool is employed to manage big data. Besides, the OENN model is used for classification process in which the optimal parameter setting of the ENN model by using Binary Grey Wolf Optimization (BGWO) algorithm. A detailed set of simulations were performed to highlight the improved performance of the BDA-OENN model. The resultant experimental values report the betterment of the BDA-OENN model over the other methods in terms of distinct performance measures. Ligent healthcare systems assists to make better decision, which further enables the patient to provide improved medical services. At the same time, skin lesion is a deadly disease that affects people of all age groups. Early, skin lesion segmentation and classification play a vital role in the precise diagnosis of skin cancer by intelligent system. But the automated diagnosis of skin lesions in dermoscopic images is a challenging process because of the problems such as artifacts (hair, gel bubble, ruler marker), This work is licensed under a Creative Commons Attribution 4.0 International License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited.
