LoDIP: Low light phase retrieval with deep image prior

no code implementations27 Feb 2024 Raunak Manekar, Elisa Negrini, Minh Pham, Daniel Jacobs, Jaideep Srivastava

Phase retrieval (PR) is a fundamental challenge in scientific imaging, enabling nanoscale techniques like coherent diffractive imaging (CDI).

Applications of ML-Based Surrogates in Bayesian Approaches to Inverse Problems

no code implementations18 Oct 2023 Pelin Ersin, Emma Hayes, Peter Matthews, Paramjyoti Mohapatra, Elisa Negrini, Karl Schulz

One particular area of scientific interest is the setting of inverse problems, where one knows the forward dynamics of a system are described by a partial differential equation and the task is to infer properties of the system given (potentially noisy) observations of these dynamics.

Applications of No-Collision Transportation Maps in Manifold Learning

1 code implementation1 Apr 2023 Elisa Negrini, Levon Nurbekyan

In this work, we investigate applications of no-collision transportation maps introduced in [Nurbekyan et.

A Neural Network Ensemble Approach to System Identification

no code implementations15 Oct 2021 Elisa Negrini, Giovanna Citti, Luca Capogna

Given samples of solutions $x(t)$ to an unknown dynamical system $\dot{x}(t)=f(t, x(t))$, we approximate the function $f$ using an ensemble of neural networks.

System Identification Through Lipschitz Regularized Deep Neural Networks

1 code implementation7 Sep 2020 Elisa Negrini, Giovanna Citti, Luca Capogna

In this paper we use neural networks to learn governing equations from data.
