Self-Normalizing Networks

Tutorials and implementations for "Self-normalizing networks"(SNNs) as suggested by Klambauer et al. (arXiv pre-print).

Versions

• Python 3.5 and Tensorflow 1.1

Note for Tensorflow 1.4 users

Tensorflow 1.4 already has the function "tf.nn.selu" and "tf.contrib.nn.alpha_dropout" that implement the SELU activation function and the suggested dropout version.

Tutorials

• Multilayer Perceptron (notebook)
• Convolutional Neural Network on MNIST (notebook)
• Convolutional Neural Network on CIFAR10 (notebook)

KERAS CNN scripts:

• KERAS: Convolutional Neural Network on MNIST (python script)
• KERAS: Convolutional Neural Network on CIFAR10 (python script)

Design novel SELU functions

• How to obtain the SELU parameters alpha and lambda for arbitrary fixed points (notebook)
