The Curse and Blessing of Mean Bias in FP4-Quantized LLM Training

Researchers have identified a simple solution to training instability in 4-bit quantized large language models by removing mean bias, which causes the dominant spectral anisotropy. This mean-subtraction technique substantially improves FP4 training performance while being hardware-efficient, potentially enabling more accessible low-bit LLM training.

Q$^2$: Quantization-Aware Gradient Balancing and Attention Alignment for Low-Bit Quantization

Researchers propose Q², a new framework that addresses gradient imbalance issues in quantization-aware training for complex visual tasks like object detection and image segmentation. The method achieves significant performance improvements (+2.5% mAP for object detection, +3.7% mDICE for segmentation) while introducing no inference-time overhead.
