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 WebFrom the lesson Practical Aspects of Deep Learning Discover and experiment with a variety of different initialization methods, apply L2 regularization and dropout to avoid model overfitting, then apply gradient checking to identify errors in a fraud detection model.

WebGradient Checking is slow! Approximating the gradient with ∂ J ∂ θ ≈ J (θ + ε) − J (θ − ε) 2 ε is computationally costly. For this reason, we don't run gradient checking at every iteration during training. Just a few times to check if the gradient is correct. Gradient Checking, at least as we've presented it, doesn't work with ...
