- QUOTE: ... In this model, the attention mechanism is used to implement local activation of the user interest. The TEM (Tree-Enhanced Embedding) model [35] uses a neural attention layer to allocate distribution weights to features of users and items to provide an explainable recommendation. ACF (Attentive Collaborative Filtering) [36] proposes both itemlevel and component-level attention mechanism to learn the implicit feedback in the multimedia recommendation. ...

- QUOTE: ... we propose a novel solution named Tree-enhanced Embedding Method (TEM), which combines embedding-based methods with decision tree-based approaches. First, we build a gradient boosting decision trees (GBDT) on the side information of users and items to derive effective cross features. We then feed the cross features into an embedding- based model, which is a carefully designed neural attention network that reweights the cross features according to the current prediction. Owing to the explicit cross features extracted by GBDTs and the easy-to-interpret attention network, the overall prediction process is fully transparent and self-explainable. Particularly, to generate reasons for a recommendation, we just need to select the most predictive cross features based on their attention scores. ...
