Last mentioned In machine learning research, an ablation study removes or changes a specific component, input feature or training technique while keeping other conditions fixed, then compares the results. It shows which parts of a system actually affect its performance or behavior.
The term comes from biology and medicine, where ablation means the removal of tissue, and echoes neuroscience experiments that remove part of the brain to learn what it does.
