Each of the plots below show one of the 16 dimensions of the character embeddings in the
lm_1b model (see this post for more context).
These are 1-dimensional plots. The x position of a character corresponds to the value of that character’s embedding in the given dimension. y position is not meaningful - characters are just jittered along that axis to avoid overlap.
The salmon markers are special meta characters with the following semantics:
- <S> and </S> mark the beginning and end of a sentence
- <W> and </W> mark the beginning and end of a word
<PAD> is used to right-pad words to the same length (50)
