Hi,

I want to get the vector (e.g., tf-idf) of a text , refine this vector, and then replace the original vector with the refined one. Is it ok by RM?

TextInput is able to provide a file containing the frequency information. Of course, we could calculate the tf-idf based on this file by ourselves, and get a new vector of tf-idf. Then, how to replace the original vector with this new vector?

Sincerely yours
gfyang

    I think I have solved it.

    A text vector is just an example in the ExampleSet, and changing the values in an example will change the corresponding text vector.

    Hi,
    the text input operators will store the text vectors in an exampleset as example. So after they finished everything is just a normal example and you might do whatever you want to to on it...
