Monitoring machine learning models is an essential part of the development process, but it can be easy to overlook specific vital considerations. A checklist helps keep track of everything you need to consider when monitoring your models and can help ensure that your models perform at their best.
Data leakage in machine learning refers to including information in the training data that would not be available at the time of prediction. This can lead to overfitting and poor generalisation because the model has been trained on data that would not be available at runtime.
