Technical Discussion: Does Low-Rank Bottleneck Hinder Information Flow in Models?

LChoshen · x · 2026-08-18

The discussion addresses the low-rank bottleneck in model architecture and whether it prevents information flow between layers. The conversation suggests that reducing vocabulary size might reduce mismatch but not necessarily improve the amount of information propagated per step, questioning if it constitutes a real improvement. It also raises the point that high dimensionality itself should be a positive signal.
