Keras quantization training Nov 07, 2018 · Note that I’ve used a 2D convolutional layer with stride 2 instead of a stride 1 layer followed by a pooling layer. Upsampling is done through the keras UpSampling layer. The bottleneck vector is of size 13 x 13 x 32 = 5.408 in this case. So about a factor 20 larger than the fully connected case. The results are, as expected, a tad better: Keras 2.2.5 was the last release of Keras implementing the 2.2.* API. It was the last release to only support TensorFlow 1 (as well as Theano and CNTK). The current release is Keras 2.3.0, which makes significant API changes and add support for TensorFlow 2.0. The 2.3.0 release will be the last major release of multi-backend Keras.
