Factorization Machines (FM) are introduced which are a new model class that combines the advantages of Support Vector Machines (SVM) with factorization models and can mimic these models just by specifying the input data (i.e. the feature vectors).

This work proposes to apply Factorization Machines (FMs) to model contextual information and to provide context-aware rating predictions and shows empirically that this approach outperforms Multiverse Recommendation in prediction quality and runtime.
Learning Attribute-to-Feature Mappings for Cold-Start Recommendations
- Zeno Gantner, Lucas Drumond, C. Freudenthaler, Steffen Rendle, L. Schmidt-Thieme
- Computer ScienceIEEE International Conference on Data Mining
- 13 December 2010
This work uses the mapping concept to construct an attribute-aware matrix factorization model for item recommendation from implicit, positive-only feedback, and shows that this approach provides good predictive accuracy, while the prediction time only grows by a constant factor.
MyMediaLite: a free recommender system library

- Computer ScienceACM Conference on Recommender Systems
- 23 October 2011
The library addresses two common scenarios in collaborative filtering: rating prediction and item prediction from positive-only implicit feedback, and contains methods for real-time updates and loading/storing of already trained recommender models.
