Tаckle оnly if yоu hаve time - This is а harder questiоn and I am giving it intentionally lower point count (only 2 points) - all ingredients to answer were presented during lecture but you need to connect the dots (the full-fledged argument was not presented explicitly in the lecture). Based on the lectures and assigned readings/videos, explain why k-fold cross-validation is a more robust method for deciding the optimal number of trees (an example of a hyperparameter) in a random forest compared to just executing a single random partitioning of the data into a training and test set, and looking at the OOB (out-of-bag) error plot based on that split. Answer in no more than 5 sentences. *** Hint: Think about, on one hand, how k-fold cross-validation works and, on the other hand, how we compute OOB error and create the plot of that OOB error relative to the number of trees in the forest.
