NOMAD is the alias for Non-locking, stOchastic Multi-machine framework for Asynchronous and Decentralized computation. This is a scalable distributed framework for various latent variable models. We have successfully applied NOMAD to two applications:

• Low-rank Matrix Factorization for Large-scale Recommender Systems
• Collapsed Gibbs Sampling for Large-scale Topic Modeling
