t3f - library for working with Tensor Train decomposition built on top of TensorFlow. t3f is a library for working with Tensor Train decomposition. Tensor Train decomposition is a generalization of the low-rank decomposition from matrices to tensors (=multidimensional arrays), i.e. it’s a tool to efficiently work with structured tensors. t3f is implemented on top of TensorFlow which gives it a few nice properties:
