I want to use embeddings learned by structured model in tree base algorithm.
(based on lesson 4 - Rossmann example)
I can extract the matrices by to_np(m.model.embs[ix].weight.data) but I also need a lookup table used by learner to correspond each item in a category to the raw in the corresponding matrix.
( I checked that the matrices are in the same order as categories in data frame.)
In other words I need to calculate the embedding layer activation on given data.
(could not find it on the forum)
