Weight decay controls distinct learning regimes in grokking transformers on modular arithmetic, tracked by new cheap attention-based diagnostics with empirical critical value and exponent fits.
Three of five cohorts now fall in the empirical 95% CI; the across-cohort mean shifts toλbound c = 0.0185±0.0074(range[0 .012, 0.028]), with the mean itself inside the empirical CI
