Abstract

In this study, a model based on Hybrid CNN-NCP and Self-Attention is proposed to recognize human activities from sensor data. The proposed model aims to improve the accuracy of human activity recognition (HAR) systems by learning spatial and temporal dependencies more effectively. The CNN layer, one of the main components of the model, extracts low-level spatial patterns from sensor data. These features are then transferred to the NCP layer, where long-term dependencies in time series data are learnt using dynamic feedback mechanisms. In the final stage, the Self-Attention mechanism improves the decision-making process of the model by focusing on critical information in different time periods. In this study, accelerometer and gyroscope sensor data are used to classify 12 different movement activities that are frequently performed in daily life. The performance of the model was evaluated by Group K-Fold cross-validation method and an average accuracy rate of 90.38% was obtained. The proposed hybrid model provides an innovative solution in HAR systems by providing higher performance compared to traditional deep learning approaches.
