Abstract:
|
Large-scale tensor regression problems are arising in more and more applications in science. Statistical models such as multi-response regression, vector auto-regressive problems and many others can be formulated as tensor regression models. When the dimension of the tensor is large, low-dimensional structure such as sparsity or low-rank need to be imposed. In this talk, I present a framework that yields general upper bounds using convex methods and lower bounds for high-dimensional tensor problems assuming the underlying tensor has low-dimensional structure based on matriculation. Our results yield optimal bounds in a number of settings in which the covariates may be dependent (e.g. auto-regressive models).
