Researchers have investigated the internal computations of depth-recurrent transformers, specifically how each token's state evolves over multiple processing loops. They found that the recurrent state converges to a fixed point for each token, though this convergence is not uniform. While the median token stabilizes by the sixth loop, approximately 10% of tokens continue to update at the typical training depth of eight. This per-token variation is crucial, as halting token processing once its output stabilizes significantly reduces computational depth without sacrificing quality. AI
IMPACT Reveals a method to potentially reduce computational costs in transformers by halting token processing once stable.
