Meaning of fut_pred in details #35

Open Niixt opened 2 years ago

Niixt commented 2 years ago

The decode() function, in the highwayNet class, is the one returning the future trajectory predicted. Before returning the trajectory, fut_pred is modified by outputActivation() in utils.py. The return value of outputActivation() is a concatenation of muX, muY, sigX, sigY and rho. The comment above tells us this output layer comes from Graves, 2015 but I don't understand the meaning of these 5 variables.

Can you explain to me the meaning of these variables?

I think it's mu for mean, sig for standard deviation, and rho for the correlation. sig is actually the reciprocal of the real sig though, according to #23.
