[D] Confusions about Entity/Categorical embeddings

Hello r/Machine Learning,

I have a couple of questions regarding entity/categircal embeddings that I hope we could clear out:

1) Can Entity/Categorical embeddings be used for an output layer (for multi-class classification task)?

2) Can I use entity/categorical embeddings if I a variable can store several categories (for example I have three classes {A, B, C} and an object can be {A and B})? Is there a python implementation for it?

3) Is Keras Embedding layer is actually performing entity embedding? The documentation doesn’t seem to be clear in this regard

Thank you 🙂
