Why architecture matters here

Dropout failures come from wrong scale + inference bugs. Architecture matters because training + inference behavior differ.

The architecture: every piece explained

The top strip is variants. Standard dropout. Inverted dropout. Attention dropout. Residual dropout.

The middle row is depth variants. Layer drop. DropPath / stochastic depth. Inference mode. Modern LLMs.

The lower rows are ops. Numerics. Metrics. Ops — rate tuning + model choice.

End-to-end flow

End-to-end: small vision-transformer trained with 0.1 dropout + stochastic depth. Val loss drops. LLM at 70B trained without dropout because data volume regularizes. Inference disables dropout completely.
