True or False a. Very flexible models have low bias and high variance. b. Assume 2 is the parameter that controls the regularization term for w in the regression problem. The larger the A is, the more complex the model (using w) will be. In S-fold cross-validation, if S = N where N is the number of samples in training dataset, then it is с. also called "leave-one-out". d. In high-dimensional space, the majority of the data distribute in a thin shell of the hyper-sphere. In noiseless coding problems, "entropy" is a lower bound on the number of bits needed to transmit a е.
