Welcome to torchTT ================== Tensor-Train decomposition in `pytorch` Tensor-Train decomposition package written only in Python on top of `pytorch`. Supports GPU acceleration and automatic differentiation. It also contains routines for solving linear systems in the TT format and performing adaptive cross approximation (the AMEN solver/cross interpolation is inspired form the `MATLAB TT-Toolbox `_). Some routines are implemented in C++ for an increased execution speed.
