Compute the cost between the true values y and the predicted values y across n = 4 observations under 12 loss: 10.05 11.217 0.91 0.65 y = y = 10.34 12.70 9.77 10.81 Hint: Recall that the loss function is only dealing with a single observation and cost looks at all observations. Jez (0 ) = 2.904 x 0%
