The … WebGradient checking is a technique that's helped me save tons of time, and helped me find bugs in my implementations of back propagation many times. Let's see how you could …
WebInstructions: Here is pseudo-code that will help you implement the gradient check. For each i in num_parameters: To compute J_plus [i]: Set θ+θ+ to np.copy (parameters_values) Set θ+iθi+ to θ+i+εθi++ε Calculate J+iJi+ using to forward_propagation_n (x, y, vector_to_dictionary ( θ+θ+ )). To compute J_minus [i]: do the same thing with θ−θ− WebFirst, don't use grad check in training, only to debug. So what I mean is that, computing d theta approx i, for all the values of i, this is a very slow computation. So to implement gradient descent, you'd use backprop to …
