Abstract

With the popularity of wearable devices and IoT technology, sensor-based human activity recognition is valuable in fields like smart healthcare. However, traditional deep learning requires large labeled datasets and struggles with new categories, users, or environments where data is scarce.

To address this, we propose a Few-Shot Transfer Learning method for Human Activity Recognition (FTL-HAR). It leverages pre-trained models to transfer knowledge, enabling adaptation to new categories with minimal data. Experiments on public datasets (PAMAP2, OPPORTUNITY) under 1-shot and 5-shot settings show that FTL-HAR significantly outperforms traditional methods by effectively utilizing pre-trained features for rapid fine-tuning.
