Nettet1. mar. 2024 · One of the key hyperparameters to set in order to train a neural network is the learning rate for gradient descent. As a reminder, this parameter scales the magnitude of our weight updates in order to minimize the network's loss function. If your learning rate is set too low, training will progress very slowly as you are making very tiny ... Nettet27. mar. 2024 · learning_rate_init double, default=0.001 The initial learning rate used. It controls the step-size in updating the weights. Only used when solver=’sgd’ or ‘adam’. …
