Title of paper "Causal Estimation of Tokenisation Bias" and schematic of how we define tokenisation bias, which is the causal effect we are interested in.

A string may get 17 times less probability if tokenised as two symbols (e.g., ⟨he, llo⟩) than as one (e.g., ⟨hello⟩)β€”by an LM trained from scratch in each situation! Our new ACL paper proposes an observational method to estimate this causal effect! Longer thread soon!

Being in a hot air balloon in Albuquerque really makes one ponder *how to efficiently pick the best translation candidate without running expensive evaluation metrics on all of them.*

See you tomorrow at 9:00 in Hall 3 #NAACL2025.

Griffin Scholars (very smart Ukrainian undergraduates from top unis) are looking for research internships in maths or CS.

(many of them can't return to Ukraine for the summer).

If you can host them (we may help with funding), please fill out this form:
