Amazon DSSTNE
Deep Scalable Sparse Tensor Network Engine, (DSSTNE), pronounced “Destiny,” is an Amazon-developed library for building Deep Learning (DL) machine learning (ML) models for recommendations. With DSSTNE, you can build recommendations systems that can model ten million unique products instead of hundreds of thousands, or NLU tasks with very large vocabularies. DSSTNE significantly outperforms current open source DL libraries on certain tasks where training data is sparse (where almost all the values are zero), common in recommendation problems.
