Hi,
Just to avoid (any possible) negative values in the output matrix.
Best,
from spdnet.
Thank you for your answer. Could you be more accurate regarding your motivation to choose this specific way to avoid negative values please (why use R
) ? For example, you could have just added abs(min(Q))
to the whole matrix if I'm not mistaken.
Sorry if this question stems from insufficient knowledge of applied maths.

I think the main reason was to make my outputs compatible with the original Matlab implementation. Maybe there is a difference in the implementation of the QR decomposition between Matlab and PyTorch.
Anyway, it was the only approach to reproduce the original paper's results. However, I think what you mentioned is also totally correct.

Okay, that answers my question. Thanks again !
