ReTrace: Rejected-Trajectory Conditioning for Speculative Decoding

Luxi Lin, Zhanpeng Zeng, Shuang Peng +2

Speculative decoding accelerates autoregressive language model inference by having a lightweight draft model propose multiple candidate tokens, which are then verified in parallel…

Empirical Bayes Conformal Prediction for Vision and Language Models

Jiapeng Zeng, Yogesh Prabhu, Zhanpeng Zeng +2

Conformal prediction (CP) gives distribution-free coverage for modern vision and language models, but it is often forced to make a ranking decision from a single unstable nonconfor…
