I have a dataset containing some user streams data for particular videos like below:
1| 2021-02-01 | 3600 | Live
My goal is to build a recommender system for watch streams.
However, I would like to find the optimal watch_stream threshold (or other approaches) that would allow me to define if a user has indeed watched a video because he/she's interested.
In other words I'd like to fill the 1s in the user_item matrix based on these information I have.
Any good approaches to suggest me? or any resources I can look up?
