Description

I tried out using seeded topic modelling, using pre-embedded documents:

model = KeyNMF(10, top_n=15, encoder=trf, vectorizer=CountVectorizer(stop_words=stop_words, min_df=50, max_df=0.85), seed_phrase='bog teater literatur')
model.fit(cleaned_corpus, embeddings=embeddings_matrix)

However, this gave me the same results as when I left out the seed_phrase:

model = KeyNMF(10, top_n=15, encoder=trf, vectorizer=CountVectorizer(stop_words=stop_words, min_df=50, max_df=0.85))
model.fit(cleaned_corpus, embeddings=embeddings_matrix)

Is it possible that the seed_phrase gets overwritten as soon as embeddings is defined?

EDIT: when I leave out embeddings=embeddings_matrix, I do get a different result. (But I want to load my pre-embedded documents.)

Research direction

Start by reproducing the two KeyNMF calls in the issue, comparing seeded and unseeded runs both with and without the precomputed embeddings argument. Trace how KeyNMF handles seed_phrase when embeddings are supplied; done means seed_phrase changes the result on the pre-embedded path without breaking unseeded behavior.
