Most real use cases don’t expose their chosen metrics to the public, even when the prediction of the model is meant to be utilized publicly, such as Open AI’s ChatGPT. However, in machine learning competitions, companies with real use cases accompanied by data publish their chosen metric publicly to find the best model that can be built. In such a setting for...
