# LiLiCorr: Lightweight Likelihood Correlation of Parallel Drafts for Speculative Decoding

Matan Rusanovsky, Yoav Miron, Roy Uziel, Omer Belhasin, Hao Guo, Ran Zilberstein, Maor Ashkenazi, Michael Elad. arXiv 2026 (2026).

Scores adjacent compatibility among top-K parallel draft candidates and selects a draft through a cheap greedy walk.

Uses the candidate–edge–path pattern with local training and inference tailored to speculative prefix acceptance.
