The author shared research insights, noting that Maximum Likelihood Estimation (MLE) actually suppresses the rich cultural knowledge embedded in model parameters. They also pointed out that the challenge of Mechanistic Interpretability (Mech interp) lies in how to intervene and manipulate model behavior during inference without degrading its original capabilities. This hypothesis was verified by observing how feature interventions alter the responses to the same prompt.
