> I'd like to do clustering our natural language data.
> The first, I used the 'seq2sparse' command to vectorize our data.
> I got sparsed vectors and a dictionary.
> And we could do k-means and got suitable clusters.
> It was OK.
> The next, I'd like to add some data to previous calculated clusters.
> So I want to get additional vectors from new additional data based on previous dictionary.
> Probably I think,
> It is impossible to get really accurate vectors by using only additional data.
> However,I'd like to reduce processing time so It's OK if I get the vector that is useful for decision tree.
> Please give me advice !
> Regard,
