Q. A dataset has 10 samples. If a test is from a single fold in a five cross fold validation, how many samples were used to train this model? Ans. 40. 5 x 10 = 50 total samples, 10 used for training and others for validation. Q. What are considerations to take while performing cross-fold validation? Ans. Temporal intermixing, maintaining the key statistics, the size of the avaliable dataset, and the number of folds to consider. Q. For what values of empirical prior are two classes balanced? Ans. Two classes are balanced if they have the same empirical prior, unbalanced otherwise. Q. Would using an aggregate performance metric like Macro F1 or Micro F1 be suitable to understand the overall performance in a test set? Ans. Yes.
