Technical discussion: Does low rank bottleneck prevent information flow?
yoavartzi · x · 2026-08-18
A technical debate on the low rank bottleneck in model architectures. One view argues reducing vocabulary mitigates mismatch but doesn't increase info; the other counters that while algebraically about gradient loss, reducing vocab size allows gradients to propagate better through more steps without the bottleneck.
