An ad recommendation system uses machine learning to choose which creative to show via an ad recommendation API, trained by feedback from customers. Testing uses automated scripts that simulate 2,000 and 10,000 simulated users with randomized genders and a 65% acceptance rate for target ads. Models sometimes flip between recommending dresses or pants because the learner chases raw popularity not demographic signal, so the implementation fails certain business scenarios and requires larger-scale, repeatable automated tests and plain‑sense acceptance criteria.
