MC Dropout (train with dropout, average K=16 softmax distributions at eval) does not improve BPB at 17M parameters. Tested dropout=0.30 (+0.005 BPB) and dropout=0.05 (+0.002 BPB). The deterministic single pass is strictly better — sub-networks lack diversity at this scale. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
