This invention discloses a fast activity recognition method based on a multi-path parallel MLP mixer architecture. First, multi-dimensional sequence data is used as input. An embedding module encodes the multi-dimensional data to obtain a feature sequence. This feature sequence is then fed into multiple MLP mixer branches, where features are mixed along the time, channel, and frequency domain dimensions, respectively. In each branch, after passing through multiple MLP mixers, global pooling is used to aggregate the feature sequence along the time dimension into a feature vector. Finally, the feature vectors obtained from each branch are concatenated and sent to a classification head for activity recognition. Compared with existing deep learning-based activity recognition methods, this invention achieves more accurate activity recognition with fewer model parameters, less floating-point computation, and faster inference speed, meeting the requirements of high precision and high efficiency in practical applications.
