Each recommender is modeled as a computational graph that consists of a structured ensemble of reusable modules connected through a set of well-defined interfaces. OpenRec is built to ease the process of extending and adapting state-of-the-art neural recommenders to heterogeneous recommendation scenarios, where different users', items', and contextual data sources need to be incorporated. **For the structure and the design philosophy of OpenRec, please refer to the following paper published in WSDM'18:** [Longqi Yang](https://ylongqi.com/), Eugene Bagdasaryan, Joshua Gruenstein, Cheng-Kang Hsieh, and [Deborah Estrin](http://destrin.smalldata.io/). 2018. [OpenRec: A Modular Framework for Extensible and Adaptable Recommendation Algorithms.](https://ylongqi.com/paper/YangBGHE18.pdf) In Proceedings of WSDM’18, February 5–9, 2018, Marina Del Rey, CA, USA. <img src="https://github.com/christinatsan/openrec-demo/blob/gh-pages/ccimage.png?raw=true" width="50"> **2020-02-17** OpenRec now uses Tensorflow 2.0 by default. Supports for Tensorflow 1.x are deprecated (all prior APIs have been moved to `openrec.tf1`). Currently supported recommendation algorithms include: * BPR (`openrec.tf2.recommenders.BPR`): Bayesian Personalized Ranking (Rendle et al., 2009) * WRMF (`openrec.tf2.recommenders.WRMF`): Weighted Regularized Matrix Factorization (Hu et al., 2008) * UCML (`openrec.tf2.recommenders.UCML`): Collaborative Metric Learning with uniformly sampled triplets (Hsieh et al., 2017) * GMF (`openrec.tf2.recommenders.GMF`): Generalized Matrix Factorization, a.k.a., Neural Collaborative Filtering (He et al., 2017) * DLRM (`openrec.tf2.recommenders.DLRM`): Deep Learning Recommendation Model, developed by Facebook (Naumov et al., 2019) **2019-07-12** OpenRec is being migrated to [Tensorflow 2.0](https://www.tensorflow.org/beta). Major changes to expect: - All OpenRec modules will be compatible with [tf.keras.layers.Layer](https://www.tensorflow.org/versions/r2.0/api_docs/python/tf/keras/layers/Layer), so that they can be used seamlessly with any Tensorflow 2.0 code base. - All OpenRec models will be compatible with [tf.keras.Model](https://www.tensorflow.org/versions/r2.0/api_docs/python/tf/keras/Model). - All input data pipelines will be compatible with [tf.data.Dataset](https://www.tensorflow.org/versions/r2.0/api_docs/python/tf/data/Dataset) but are made much more friendly for recommendation models. - Minimizing boilerplate while keeping the modularity and adaptability of OpenRec. To get things started, we introduce OpenRec (Tensorflow 2.0) implementations of [deep learning recommendation model (DLRM)](https://github.com/facebookresearch/dlrm). Check out `tf2_examples/dlrm_criteo.py`. To experiment with these new features, do `pip3 install .` inside the repo and then `import openrec.tf2`. You need to have Tensorflow 2.0 installed (Follow the instructions [here](https://www.tensorflow.org/beta)). More examples, tutorials and documents will be available soon. Check out `tf2_examples/`. **2018-08-31** Introducing new modular interfaces for OpenRec. Major changes: - A new paradigm for defining, extending, and building recommenders. - Remove boilerplate class structure of recommenders. - Introduce a macro-based recommender construction paradigm. - Disentangle module construction and connection. - Support module construction directly using Tensorflow and Keras APIs. - A more efficient and customizable pipeline for recommender training and evaluation. - A new Dataset class for complex data input. - A customizable ModelTrainer handling complex training/evaluation scenarios. - Caching mechanism to speed up eva
