Information Entropy Invariance: Enhancing Length Extrapolation in Attention Mechanisms

1 code implementation15 Jan 2025 Kewei Li, Yanwen Kong, Yiping Xu, Jianlin Su, Lan Huang, Ruochi Zhang, Fengfeng Zhou

Since the emergence of research on improving the length extrapolation capabilities of large language models in 2021, some studies have made modifications to the scaling factor in the scaled dot-product attention mechanism as part of their proposed methods without rigorous theoretical justifications.

TemporalPaD: a reinforcement-learning framework for temporal feature representation and dimension reduction

no code implementations27 Sep 2024 Xuechen Mu, Zhenyu Huang, Kewei Li, Haotian Zhang, Xiuli Wang, Yusi Fan, Kai Zhang, Fengfeng Zhou

The Policy Module, responsible for dimensionality reduction through RL, functions as the actor, while the Representation Module for feature extraction and the Classification Module collectively serve as the critic.
