Standalone Mixture-of-Experts (MoE) layer

MoE layers provide a flexible way to scale deep models to train on larger datasets. The aim of this example should be to show how replace the regular layers (such as Dense, Conv2D) with compatible MoE layers.

Guide to report the efficiency of a Keras model

It's often important to report the efficiency of a model. But what factors should be included when reporting the efficiency of a deep learning model? The Efficiency Misnomer paper discusses this thoroughly and provides guidelines for practitioners on how to properly report model efficiency.

The objectives of this guide will include the following:

• What factors to consider when reporting model efficiency?
• How to calculate certain metrics like FLOPS, number of examples a model can process per second (both in training and inference mode), etc?
