Encoder - Neural Network Compression

This tutorial has a full implementation https://machinelearningmastery.com/autoencoder-for-regression/

There is also one for classification: https://machinelearningmastery.com/autoencoder-for-classification/

I think this text has important information regarding the representation in the autoencoder, why compression may explain better results in ML models: https://neptune.ai/blog/representation-learning-with-autoencoder
