TensorFlow implementation of a library for working with Tensor Train (TT) decomposition which is also known as Matrix Product State (MPS).

Documentation

The documentation is available via readthedocs.

Comparison with other libraries

There are about a dozen other libraries implementing Tensor Train decomposition. The main difference between t3f and other libraries is that t3f has extensive support for Riemannian optimization and that it uses TensorFlow as backend and thus supports GPUs, automatic differentiation, and batch processing. For a more detailed comparison with other libraries, see the corresponding page in the docs.
