User-dependent cost functions #7
Description
Currently, all (two) implemented cost functions are independent of user-related information.
They result in the same recommendation for every person (since they are only dependent on the attributes of the respective Courseware section(s)).
It would be interesting to test whether it is also possible to implemented cost functions dependent on user information.
However, with the current setup, all cost values are stored in the database. User-dependent cost functions would probably require different database tables. Moreover, they would require the storage of a lot of cost values (possibly course x first section x second section x user many). This may be infeasible.
