WebBecause regularization causes J(θ) to no longer be convex, gradient descent may not always converge to the global minimum (when λ > 0, and when using an appropriate learning rate α). Regularized logistic regression and regularized linear regression are both convex, and thus gradient descent will still converge to the global minimum. True
