Hello, sir.

I have run your code on my dataset. My metapath is UPDPU. (user- project-discipline). And I want to recommend co-workers to the applicant of project which belonging to the discipline. But I just got the matrix which row is user, column is project and data is the rating. The rating is meaningless.

I want get the target matrix which row is user, column is user and data is the similarities between users. How can i adjust the input to get that matrix?

Do you mean recommend a user for each user?

In my recommendation system, when a user want to apply a project, I will recommend many other users to him as co-workers. These users are similar with him.

I have another question:
I got the final prediction matrix (row-column : user-project). Could the user be expressed as follow expression?
U0 = α0P0 + α1P1 + ... + αnPn = ΣαiPi
If the expression is resonable, Could the prediction matrix 8000 (row-column : project-user) be represented as the transpose of above matrix (row-column : user-project)?
P0 = α0U0 + α1U1 + ... + αnUn = ΣαiUi
