Power Analysis

A mathematical determination that an observed experimental result is likely caused by a specific factor rather than random chance.

A statistical range that estimates where a true value is likely to lie with a specified level of confidence based on sampled data.

The practice of keeping variables, conditions, and procedures consistent across experiments so that observed differences in outcomes can be attributed to the factors being tested.

An experimentation method that compares two variants under similar conditions to determine which performs better against predefined metrics.

An experimentation method that tests multiple variables and their combinations simultaneously to measure their effects on an AI system or product.

The process of recording and managing information about AI experiments, including datasets, models, hyperparameters, code versions, metrics, and outcomes to enable reproducibility and comparison.
