New attention quantization speeds up tabular foundation models

Researchers have developed a new attention quantization strategy for tabular foundation models to improve inference performance. This method focuses on quantizing queries, keys, and values to FP8, leveraging explicit FP8 matrix multiplication instructions. A key finding is the necessity of aligning quantization error between training and testing data to prevent accuracy degradation. The developed Triton kernel demonstrated up to a 1.7x speedup over standard 16-bit kernels without significant accuracy loss on models like TabPFN-v3 and TabICLv2 across benchmark datasets. AI

IMPACT This research could lead to more efficient deployment and usage of tabular foundation models, reducing computational costs and latency.
