Cold-Start Prediction Task

A Cold-Start Prediction Task is an entity prediction task with little entity information (especially predictor information).

• Context:
  • It can (typically) range from being an Item Cold-Start Prediction Task to being a User Cold-Start Prediction Task.
  • …
• Example(s):

  • QUOTE: One difficult, though common, problem for a recommender system is the cold-start problem, where recommendations are required for items that no one (in our data set) has yet rated.1 Pure collaborative filtering cannot help in a cold-start setting, since no user preference information is available to form any basis for recommendations.
