  on: SAE re­con­struc­tion er­rors are (em­piri­cally) pathological

  One explanation for pathological errors is feature suppression/​feature shrinkage (link). I’d be interested to see if errors are still pathological even if you use the methodology I proposed for finetuning to fix shrinkage. Your method of fixing the norm of the input is close but not quite the same.

  The original perplexity of the LLM was ~38 on the open web text slice I used. Thanks for the compliments!
