Model Introduction
=====================
We implement 91 recommendation models covering general recommendation, sequential recommendation,
context-aware recommendation and knowledge-based recommendation. A brief introduction to these models are as follows:
General Recommendation
--------------------------
In the class of general recommendation, the interaction of users and items(.inter file) is the only data
that can be used by model. Usually, the models are trained on implicit feedback data and evaluated under the
task of top-n recommendation. All the collaborative filter(CF) based models are classified in this class.

Context-aware Recommendation
-------------------------------
Context-aware recommendation can be seen as an extension of click-through rate prediction. All the model in this
class can be used for CTR prediction. Usually, the dataset is explicit and contains label field. Other feature fields
are also support for these models. And evaluation is always conducted in the way of binary classification.

Sequential Recommendation
---------------------------------
The task of sequential recommendation(next-item recommendation) is the same as general recommendation which sorts a list of items according
to preference. While the history interactions are organized in sequences and the model tends to characterize
the sequential data. The models of session-based recommendation are also included in this class.

Knowledge-based Recommendation
---------------------------------
Knowledge-based recommendation introduces an external knowledge graph to enhance general or sequential recommendation.
