slimTrain -- A Stochastic Approximation Method for Training Separable Deep Neural Networks

1 code implementation28 Sep 2021 Elizabeth Newman, Julianne Chung, Matthias Chung, Lars Ruthotto

In the absence of theoretical guidelines or prior experience on similar tasks, this requires solving many training problems, which can be time-consuming and demanding on computational resources.

Train Like a (Var)Pro: Efficient Training of Neural Networks with Variable Projection

1 code implementation26 Jul 2020 Elizabeth Newman, Lars Ruthotto, Joseph Hart, Bart van Bloemen Waanders

To solve the optimization problem more efficiently, we propose the use of variable projection (VarPro), a method originally designed for separable nonlinear least-squares problems.

Non-negative Tensor Patch Dictionary Approaches for Image Compression and Deblurring Applications

no code implementations25 Sep 2019 Elizabeth Newman, Misha E. Kilmer

Building on that work, in this paper, we use of non-negative tensor patch-based dictionaries trained on other data, such as facial image data, for the purposes of either compression or image deblurring.

Stable Tensor Neural Networks for Rapid Deep Learning

no code implementations15 Nov 2018 Elizabeth Newman, Lior Horesh, Haim Avron, Misha Kilmer

To exemplify the elegant, matrix-mimetic algebraic structure of our $t$-NNs, we expand on recent work (Haber and Ruthotto, 2017) which interprets deep neural networks as discretizations of non-linear differential equations and introduces stable neural networks which promote superior generalization.

Image classification using local tensor singular value decompositions

no code implementations29 Jun 2017 Elizabeth Newman, Misha Kilmer, Lior Horesh

From linear classifiers to neural networks, image classification has been a widely explored topic in mathematics, and many algorithms have proven to be effective classifiers.
