how the feature "time elapsed since previous session" and "number of tracks in previous session" used?

[animesh-wynk]

hi!

for simplicity, lets call the feature "time elapsed since previous session" f1
and "number of tracks in previous session" f2

doubts related to f1:

1. is f1 in hours or minutes or is it in some other unit?
2. how are you normalising this feature?

doubts related to f12:

1. it is mentioned in the paper that in your dataset, avg number of songs in user sessions is 10, and that you have only considered the first 10 songs in a session to compute the session embedding. then how is the f2 calculated? is it the actual number of songs in the previous song?
2. how is this feature normalised?

thanks a lot in advance : )

Hi @animesh-wynk, unfortunately I don't remember these implementation details. The code is the authoritative resource for these questions, hopefully you should be able to find the answers to there in the code.
