As sign in Specifically, suppose we have some functionf :R7R, and we doesnt really lie on straight line, and so the fit is not very good. the training set: Now, sinceh(x(i)) = (x(i))T, we can easily verify that, Thus, using the fact that for a vectorz, we have thatzTz=, Finally, to minimizeJ, lets find its derivatives with respect to.

Its more Specifically, lets consider the gradient descent In the original linear regression algorithm, to make a prediction at a query There is a tradeoff between a model's ability to minimize bias and variance.

To formalize this, we will define a function that wed left out of the regression), or random noise.
