For the following problem, select all answers that are correct. Under certain conditions, minimizing mean-squared error for linear regression is equivalent to maximizing the log-likelihood of a probabilistic model. As a reminder, the mean-squared error is defined as E (Yn – aw)². The probabilistic model assumes that 1. Lmse (w) = 2N Yn xw + En, where En is a "noise variable" that describes the prediction error. What conditions are necessary for the equivalence? A) The noise parameter E, should follow a normal distribution. B) The parameter N follows an Einstein distribution C) The conditional probability p (yn |æn, w) should follow a Poisson distribution. D) The conditional probability p(yn |æn, w) should follow a Gaussian distribution. O A D B.
