Question: Normal equation method requires computing X, X^T, (X^TX)^(-1) and y to be able to compute theta. Suppose number of training examples m = 8 and

Normal equation method requires computing X, X^T, (X^TX)^(-1) and y to be able to compute \theta. Suppose number of training examples m = 8 and the number of features is 4 (excluding the all 1 feature). Write down the dimension of each of the following 5 matrices:X, X^T, (X^TX)^(-1), y, and \theta.Note: ^ denotes superscript since we are using plaintext to write the question
