Ablation Studies

Ablation studies remove or replace individual components of a model or training pipeline to quantify each one's contribution, confirming that every part is necessary.

Where is it used?

The original Transformer paper ablated multi-head attention and positional encoding; LoRA ablated rank and target modules; DPO ablated beta and reference model presence.

How to build it

Train the full model and variants with one component removed (e.g., no residual, no LayerNorm), log validation loss in `wandb`, and report a table of metric deltas per ablation.
