section 3.2 states that



Inspired by continuous bag of words language models [14],
we learn high dimensional embeddings for each video in a
fixed vocabulary and feed these embeddings into a feedforward neural network.


  1. They don't say how they created the embeddings (I guess something like https://towardsdatascience.com/using-word2vec-for-music-recommendations-bb9649ac2484)


  2. I can't tell if the embeddings they created (for vidoes) is trainable in their candidate generation step or ranking step?

How about these video embeddings on the above image? (Ranking Step)
