TL;DR. An experiment that removes one component of a system at a time to measure its individual contribution.

Technical Definition

An experiment that removes one component of a system at a time to measure its individual contribution.

How it works

'We added X, Y, and Z and the score went up' is not enough — an ablation removes each in turn to show which actually matter. Standard practice in ML papers and a powerful debugging tool for production systems.

Related Concepts

• Experiment Tracking — Systematically recording the inputs, code, parameters, and outputs of every ML experiment.
• Benchmark — A standardized dataset and evaluation protocol used to compare models.
• Reproducibility — The ability for others to re-run an experiment and obtain the same results.
