Researchers have investigated the formation dynamics of modular task partitions within large language models during their early training stages. By training a Pythia-410M model and analyzing its internal organization at each step, they discovered that modularity is largely pre-determined by the architecture before significant learning occurs. The study also observed sharp increases in modularity, accompanied by skewed gradient distribution, which appear to be linked to the learning process within specific domains. AI
