Weight normalization layer for TensorFlow

Project description


Weight Normalization layer wrapper for TensorFlow-Keras API.

Inspired by Sean Morgan implementation, but:

  • No data initialization (only eager mode was implemented in original pull request).
  • Code refactoring
  • More tests
  • CIFAR10 example from original paper reimplemented


Unfortunately I couldn't reproduce parer results on CIFAR10 with batch size 100. As you can see there is no much difference in accuracy.

But with much smaller batch size model with weight normalization is much better then regular one.

How to use

import tensorflow as tf
from tfwn import WeightNorm

dense_wn = WeightNorm(tf.keras.layers.Dense(3))
out = dense_wn(input)
