"How get term-document matrix for SVD?"
When I use the ProcessDocument module it creates a document-term matrix. I need to create a term-document matrix to feed to SVD. I.e.,
doc1 doc2 doc3
term1
term2
term2
I placed WordListtoDocument after it and fed the output to SVD, but the output from WordListtoDocument doesn't have the correct format - SVD generates an error.
This is representative of how I set up the ProcessDoc(word) ->(word) WordListtoDoc (example set) -> (example set)SVD modules.
ProcessDoc(example set) ->(example set) Transpose(example set) -> (example set)SVD
How should I set this up?
TIA
