Dissecting Transformer Length Extrapolation via the Lens of Receptive Field Analysis

Ta-Chung Chi, Ting-Han Fan, Alexander I. Rudnicky +1

Length extrapolation permits training a transformer language model on short sequences that preserves perplexities when tested on substantially longer sequences. A relative position…

A Contraction Approach to Model-based Reinforcement Learning

Ting-Han Fan, Peter J. Ramadge

Despite its experimental success, Model-based Reinforcement Learning still lacks a complete theoretical understanding. To this end, we analyze the error in the cumulative reward us…
