Interview Prompt
We track every training run for our ML models, and each run records the framework used and the accuracy it reached. For each model, find the framework spanning the most of its versions and report that model-framework pair with its average accuracy. Keep only the pairs whose average accuracy is among the three highest.
Summary
Every framework has a star model.
