Fractional Deep Neural Network via Constrained Optimization

no code implementations1 Apr 2020 Harbir Antil, Ratna Khatri, Rainald Löhner, Deepanshu Verma

This paper introduces a novel algorithmic framework for a deep neural network (DNN), which in a mathematically rigorous manner, allows us to incorporate history (or memory) into the network -- it ensures all layers are connected to one another.

Bilevel Optimization, Deep Learning and Fractional Laplacian Regularization with Applications in Tomography

no code implementations22 Jul 2019 Harbir Antil, Zichao, Di, Ratna Khatri

As an example, we consider tomographic reconstruction as a model problem and show an improvement in reconstruction quality, especially for limited data, via fractional Laplacian regularization.
