Abstract: In this manuscript, video-based activity classification using hierarchical auto-associative polynomial convolutional neural network (V-AC-HA-APCNN) optimised with adolescent identity search algorithm is proposed. Initially, the input action data are taken from Weizmann action dataset. The input data is pre-processed with the help of trilateral filter. Then these pre-processed data are given to force-invariant improved feature extraction (FII-FE) approaches for extracting the necessary features of the video data. These extracted features are given to hierarchical auto-associative polynomial convolutional neural network (HA-APCNN) for classifying the human activities such as walk, run, bend, and skip. Adolescent identity search algorithm (AISA) is considered to enhance the HA-APCNN weight parameters. The performance of the proposed V-AC-HA-APCNN approach attains 32.3%, 56.6%, and 65.5% higher accuracy, and 34.4%, 43.2%, and 32.1% higher ROC compared with existing methods. The intention of this paper is to examine the deep learning methods for the classifications of video-based anomalous activity and focused on anomaly classification.
