Suppose we wanted to find the best model complexity to use for polynomial regression for degrees p using cross- validation. Suppose that we have a training dataset with 100 examples in it, and we want to search over the possible degrees = n/2 for the number of chunks in cross-validation (where n is [0, 1, 2, 4, 8, 16, 32]. We decide to use k the number of examples in the training set). What is the total number of predictors we will need to train to find the optimal model complexity. Enter your answer as a number.
