Mech Interp is a Verifiable Task.

LessWrongAnalysis or commentary·
AI brief

A LessWrong post argues that mechanistic interpretability can be framed as a verifiable task, describing an approach where hypothesized components of MLP layers are replaced with the algorithm they are thought to compute and checked against reconstruction loss.

Written by AI from LessWrong's published text.

“If we think parts of MLP0-MLP3 are computing [a sorting algorithm], we can replace those parts with [a sorting algorithm] and check reconstruction loss. [1] However, reconstruction loss is not enough.”
