RaBiT: A Residual-Aware Binarization Training Method for Accurate and Efficient LLMs

·2026.07.29 15:20

Key point

RaBiT is proposed as a binarization training technique that leverages residuals to improve accuracy while maximizing the efficiency of LLMs.

Details

Binarization, a technique that compresses weights to 1-bit to improve the inference efficiency of LLMs, has been attracting attention, but existing methods have had the limitation of causing a sharp drop in model accuracy.

RaBiT (Residual-Aware Binarization Training) introduces a new framework that precisely manages the residual generated during the training process to solve this problem. Through this, it minimizes performance loss in the model while compressing weights to an extreme degree.

The key features and results are as follows:

  • Residual-Aware Training: Actively utilizes residual information in training to compensate for the information loss that occurs during the binarization process.
  • Maximized Efficiency: Dramatically reduces the model's parameter size, decreasing memory usage and increasing inference speed.
  • Maintaining High Accuracy: Maintains the language modeling performance of LLMs much more stably compared to existing binarization techniques.
