Uncovering Mechanistic Interpretability in Machine Learning
There is a mystery around how machine learning models like neural networks, once unable to perform addition, suddenly start grasping it. Even with improved accuracy, the mechanism behind this leap is not clear. The phenomenon of models becoming better at tasks before reaching the right answer hints at a continuous underlying process. The concept of a preexisting circuit that gains strength or a weak circuit that improves is puzzling researchers. The quest for mechanistic interpretability seeks to unravel whether certain abilities of models will remain hidden even with increased scale.
