Tree-enhanced Embedding Model

This is our project for the paper:

Xiang Wang, Xiangnan He, Fuli Feng, Liqiang Nie and Tat-Seng Chua (2018). TEM: Tree-enhanced Embedding Model for Explainable Recommendation. In WWW'18, Lyon, France, April 23–27, 2018.

Author: Dr. Xiang Wang (xiangwang at u.nus.edu)

Introduction

Tree-enhanced Embedding Mode (TEM) is a new recommendation framework, which combines the strong representation ability of embeddingbased and interpretability of tree-based models. At its core is an easy-to-interpret decision-tree and attention network, making the recommendation process fully transparent and explainable.
