  • πŸ“ŒKind of List
    top{types} : not weighted anything
    non_weighted
    {types}{weekday}_top_list : weekday weighted, not time weighted
    {types}
    {weekday}_top_list ; weekday & time weighted
  • πŸ“Œwhat I did in the best score
    : changed list 'top{types}'
    to list '{types}
    {weedkay}_top_list' (which time & weekday weighted)
  • πŸ“Œwhen the list 'top{types}' used?
    : When althoug after applying the covisitaion matrix,
    there are not enough(less than 20) aids for the result.
    Then, bring elements from list 'top
    {types}' to make len(result) to 20
  • πŸ“ŒProblems
    I only chaged the list 'top_{types}'
    So, weekday weighted only used when (after applying the covisitation matrix)
    there are not enough aids in the result. But there aren't too much aid like this.
  • πŸ“ŒQuestions
    Is there any meaningful changes when edit the result list(made by covisitation matirx)
    = Is 'Weekday & time Weight' has more affect than 'co-visitation Matrix' ?
  • πŸ“ŒAnanlysis
    -when apply the time weighted to the weekday weighted, there are about 3 items are different.
    -'non weighted' and 'time&weekday weighted' has same aids about 7~10
