Swish activation function keras8/14/2023 ![]() So far I can't feel the power of the swish activation function. So, if the input itself is useless and the algorithm can’t make sense of the input, then the output is consequently useless as well. Activation functions basically determine the output of a function based on the input. It seems that swish is not powerful as I expect, and swish need about 20% extra time to train.Īlso compare with their training history, relu seem got better training curve. Activation functions are the algorithms that the neurones use to sort out useful data from useless data. If swish really better than relu? swish confusion matrix fit( x_train, y_train, batch_size = 100, epochs = 100, validation_data =( x_test, y_test) activation: Activation function, such as tf.nn.relu, or string name of built-in activation function, such as 'relu'. add( Dense( units = 1, activation = 'sigmoid', kernel_initializer = 'uniform'))Ĭlassifier. Applies an activation function to an output. add( Dense( units = 5, activation = swish, kernel_initializer = 'uniform'))Ĭlassifier. add( Dense( units = 10, activation = swish, kernel_initializer = 'uniform'))Ĭlassifier. How to Choose an Activation Function for Deep Learning Photo by Peter Dowley, some rights reserved. The activation function for output layers depends on the type of prediction problem. The modern default activation function for hidden layers is the ReLU function. add( Dense( units = 25, activation = swish, kernel_initializer = 'uniform'))Ĭlassifier. Activation functions are a key part of neural network design. ![]() add( Dense( units = 50, activation = swish, kernel_initializer = 'uniform'))Ĭlassifier. add( Dense( units = 10, activation = swish, kernel_initializer = 'uniform', input_dim = 10))Ĭlassifier. utils import class_weight from keras import backend as K def swish( x): layers import Dense, Activation from keras import optimizers from sklearn. ![]()
