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.
