Technical discussion: BPE padding and representation learning
kalomaze · x · 2026-08-19
A discussion suggests that padding to the maximum bit count of a BPE tokenizer could theoretically enable specific operations on a standard autoregressive model. The argument is that mappings like 8-to-4096 are algebraically overdetermined, and this overdetermination could be fundamentally better for learning representations compared to arbitrary token values.
