WebNov 26, 2024 · In Tensorflow-Keras, a training loop can be run by turning on the gradient tape, and then make the neural network model produce an output, which afterwards we can obtain the gradient by automatic differentiation from the gradient tape. Subsequently we can update the parameters (weights and biases) according to the gradient descent … WebMar 8, 2024 · Typically you'll use this to calculate the gradient of a model's error or loss with respect to its weights. x = tf.Variable(1.0) def f(x): y = x**2 + 2*x - 5 return y f(x) At x = 1.0, y = f (x) = (1**2 + 2*1 - 5) = -2. The derivative of y is y' = f' (x) = (2*x + 2) = 4.
