# Activations

We support all [Keras activation functions](https://keras.io/activations), namely:

*  softmax
*  elu
*  selu
*  softplus
*  softsign
*  relu
*  tanh
*  sigmoid
*  hard\_sigmoid
*  linear

The mapping of Keras to DL4J activation functions is defined in [KerasActivationUtils](https://github.com/eclipse/deeplearning4j/blob/master/deeplearning4j/deeplearning4j-modelimport/src/main/java/org/deeplearning4j/nn/modelimport/keras/utils/KerasActivationUtils.java)
