Nettet19. jul. 2024 · The learning rate α determines how rapidly we update the parameters. If the learning rate is too large, we may “overshoot” the optimal value. Similarly, if it is too small, we will need too many iterations to converge to the best values. That’s why it is crucial to use a well-tuned learning rate. So we’ll compare the learning curve of ... NettetIn Keras, you can set the learning rate as a parameter for the optimization method, the piece of code below is an example from Keras documentation: from keras import optimizers model = Sequential () model.add (Dense (64, kernel_initializer='uniform', input_shape= (10,))) model.add (Activation ('softmax')) sgd = optimizers.SGD (lr=0.01, …

Nettet12. jun. 2024 · Using a low learning rate can dramatically improve the perfomance of your gradient boosting model. Usually a learning rate in the range of 0.1 to 0.3 gives the best results. Keep in mind that a low learning rate can significantly drive up the training time, as your model will require more number of iterations to converge to a final loss value. NettetThe objectives of the cyclical learning rate (CLR) are two-fold: CLR gives an approach for setting the global learning rates for training neural networks that eliminate the need to perform tons of experiments to find the best values with no additional computation.
