Parameter-Efficient Fine-Tuning for HAR: Integrating LoRA and QLoRA into Transformer Models

arXiv — cs.LGTuesday, December 23, 2025 at 5:00:00 AM
  • A recent study has introduced parameter-efficient fine-tuning techniques for Human Activity Recognition (HAR), specifically integrating Low-Rank Adaptation (LoRA) and Quantized LoRA into transformer models. This approach aims to enhance the adaptability of large pretrained models to new domains while addressing computational resource limitations on target devices.
  • The significance of this development lies in its potential to match the performance of full model fine-tuning while drastically reducing the number of trainable parameters, memory usage, and training time, making HAR more accessible for various applications.
  • This advancement reflects a growing trend in artificial intelligence towards optimizing model efficiency, as seen in various innovations like AuroRA and qa-FLoRA, which also focus on enhancing LoRA's capabilities in different contexts, thereby contributing to the ongoing evolution of machine learning methodologies.

A new framework named RefVFX has been introduced, enabling the transfer of complex temporal effects from a reference video to a target video or image in a feed-forward manner. This innovation addresses challenges in dynamic temporal effects, such as lighting changes and character transformations, which are difficult to articulate through text or static conditions.
