Tensor Networks for Machine Learning Applications

Interdisciplinary Areas: Data/Information/Computation

Project Description

The main aim of the project is to study the tradeoffs between computational complexity, description complexity and statistical inference through the lens of tensor algebraic framework, exploiting low rank tensor representations. Tensor factorization and representations lead to polynomial complexity representations of an exponentially large data, which are modeled as multidimensional arrays of numbers indexed along several axes a.k.a. tensors. Recently, there has been a surge in
using tensor algebraic methods (utilizing the structure of tensor networks) that have proven to be quite useful in a variety of applications where the data is inherently or naturally multidimensional, as well as in several other applications such as deep learning and clustering where the problem can be embedded into a tensor algebraic setting. The project aims to consider both the fundamental limits and applications of tensor networks in a variety of settings, like scattering theory.
