Or with separate equations for each layer:






● dout = 1

● dout = k > 1 k

● k

● Input: one-hot word vectors 1 x |V|
● Each input one-hot vector is fully

connected to an embedding layer
(word projection) by an embedding
matrix E for word embeddings of
dimension d, so E is d x |V| (one
embedding row per word)

● When conditioning on 3 past words,
the projection layer will be 1 x 3d

● Note that back propagation of Loss
will update E, which is shared
across words
