Researchers have identified that the transition from memorization to generalization in Transformer models, a phenomenon known as grokking, is not due to a module switch but rather a spectral recoding of existing distributed circuits. Their study, using "Transition Games," found that utility gains are distributed, with specific modes in block-0 attention and block-1 MLP playing significant roles. Contrary to a common prediction, the MLP did not solely memorize while attention generalized; instead, the grokking process involved a more complex spectral recoding. AI
