Swish activation function keras8/18/2023 ![]() The simplicity of Swish and its similarity to ReLU make itĮasy for practitioners to replace ReLUs with Swish units in any neural network. For example, simply replacing ReLUs with Swish units improves top-1Ĭlassification accuracy on ImageNet by 0.9\% for Mobile NASNet-A and 0.6\% for As such, a careful choice of activation function must be made for each deep learning neural network project. The choice of activation function in the output layer will define the type of predictions the model can make. To work better than ReLU on deeper models across a number of challengingĭatasets. The choice of activation function in the hidden layer will control how well the network model learns the training dataset. Our experiments show that the best discovered activationįunction, $f(x) = x \cdot \text(\beta x)$, which we name Swish, tends The searches by conducting an empirical evaluation with the best discoveredĪctivation function. Using a combination of exhaustive and reinforcement learning-based search, weĭiscover multiple novel activation functions. 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. To leverage automatic search techniques to discover new activation functions. Activation functions are a key part of neural network design. Have managed to replace it due to inconsistent gains. Currently, the most successfulĪnd widely-used activation function is the Rectified Linear Unit (ReLU).Īlthough various hand-designed alternatives to ReLU have been proposed, none On the training dynamics and task performance.
