Three-way recommender systems based on random forests
作者:
Highlights:
•
• We propose a framework integrating three-way decision and random forests.
• We introduce a new recommender action to consult the user for the choice.
• We build a random forest to predict the probability that a user likes an item.
• The three-way thresholds are optimal for both the training set and the testing set.
