Researchers have introduced ResiSpec, a new framework designed to enhance the efficiency of speculative decoding in large language models. Speculative decoding typically uses a draft model to predict future tokens, which are then verified by a larger model. However, multi-candidate approaches can suffer from 'residual drift,' where the rejection of early candidates causes the distribution of subsequent candidates to diverge, leading to inefficient resampling. ResiSpec addresses this by reformulating the proposal distribution during verification, keeping the residual target mass within the draft model's high-confidence areas. This method reportedly achieves up to a 1.92x speedup compared to existing multi-candidate techniques without sacrificing output accuracy. AI
