BPE is a greedy method to find a tokeniser which maximises compression! Why don't we try to find properly optimal tokenisers instead? Well, it seems this is a pretty difficult—in fact, NP-complete—problem!🤯 New paper + @philipwitti.bsky.social @gregorbachmann.bsky.social :) arxiv.org/abs/2412.15210

Tokenisation is NP-Complete

In this work, we prove the NP-completeness of two variants of tokenisation, defined as the problem of compressing a dataset to at most $δ$ symbols by either finding a vocabulary directly (direct token...
