A Review on Transformer-Based Methods for Human Activity Recognition

With the expansion of smart homes, Human Activity Recognition (HAR) has become a key challenge in artificial intelligence, enhancing not only the comfort and safety of residents but also contributing to the development of applications such as healthcare and smart surveillance. The Transformer architecture, with its ability to model long-term dependencies and process data in parallel, has made significant advancements in recognizing human activities. In addition, its multi-head attention mechanism enables the analysis of complex input data by allowing the model to focus on different parts of the input simultaneously, capturing diverse relationships and dependencies within the data. This paper examines the application of Transformers in HAR and analyzes recent studies (since ۲۰۱۹). In addition to investigating innovative architectures, feature extraction methods, and accuracy improvements, it also discusses the challenges and future prospects of these models in recognizing human activities. Rapid advancements in deep learning and access to extensive datasets have made Transformers a key tool for improving the accuracy and efficiency of HAR systems in smart environments.
