Modified Wild Horse Optimization with Deep Learning Enabled Symmetric Human Activity Recognition Model

Abstract

Traditional indoor human activity recognition (HAR) is a timeseries data classification problem and needs feature extraction. Presently, considerable attention has been given to the domain of HAR due to the enormous amount of its real-time uses in real-time applications, namely surveillance by authorities, biometric user identification, and health monitoring of older people. The extensive usage of the Internet of Things (IoT) and wearable sensor devices has made the topic of HAR a vital subject in ubiquitous and mobile computing. The more commonly utilized inference and problemsolving technique in the HAR system have recently been deep learning (DL). The study develops a Modified Wild Horse Optimization with DL Aided Symmetric Human Activity Recognition (MWHODL-SHAR) model. The major intention of the MWHODL-SHAR model lies in recognition of symmetric activities, namely jogging, walking, standing, sitting, etc. In the presented MWHODL-SHAR technique, the human activities data is pre-processed in various stages to make it compatible for further processing. A convolution neural network with an attention-based long short-term memory (CNN-ALSTM) model is applied for activity recognition. The MWHO algorithm is utilized as a hyperparameter tuning strategy to improve the detection rate of the CNN-ALSTM algorithm. The experimental validation of the MWHODL-SHAR technique is simulated using a benchmark dataset. An extensive comparison study revealed the betterment of the MWHODL-SHAR technique over other recent approaches.

“…The experimental gesture-detection outcome of the IGSPO-DBN method is compared with other approaches in Table 3 and Figure 7 (Tahir et al, 2023). Based on accu y , the IGSPO-DBN system highlights a higher value of 99.43% while the MWHODL-SHAR, CNN-RF, Residual network, Deep CNN, CAE, HARSI, and LSTM approaches indicated reducing values of 99.…”
