Many fields function with large databases constitute a high number of features. Feature selection strategies seek to exclude the features that are distracting, repetitive, or unnecessary, as they can degrade the classification results. Existing approaches lack the scalability needed to handle the datasets with millions of instances and they do not obtain favorable results in a timely manner. This study uses a unique feature selection approach based on an upgraded optimization model and deep machine learningābased data classification. ā(a) Feature extraction, (b) optimal feature selection, and (c) classificationā are the three stages of the proposed model. Initially, the extracted bigādatasets are efficiently handled by the parallel pool mapāreduce architecture. Several features from the input bigādata are extracted using feature extraction (FE) approaches such as the suggested TriāKernel principal component analysis (TKāPCA), linear discriminant analysis, and linear square regression. Furthermore, the data obtained characteristics may contain data that is irrelevant, outāofādate, or noisy. The computing cost rises due to the larger feature space. As a result, the best features are selected using a new optimization technique known as Levy Adapted SLnO (LAāSLnO), which is a superior variant of the original SLnO algorithm. This selection of appropriate features improves the classification accuracy. For classification, Convolutional Neural Network is used in this work. Finally, a comparative evaluation is undergone to validate the efficiency of the proposed model.
