Active Learning for Conditional Generative Compressed Sensing

Alexander DeLise, Nick Dexter

Generative compressed sensing uses the range of a pretrained generator as a nonlinear model for recovering structured signals from limited measurements. We study a conditional vers…

Optimal deep learning of holomorphic operators between Banach spaces

Ben Adcock, Nick Dexter, Sebastian Moraga

Operator learning problems arise in many key areas of scientific computing where Partial Differential Equations (PDEs) are used to model physical systems. In such scenarios, the op…

A unified framework for learning with nonlinear model classes from arbitrary linear samples

Ben Adcock, Juan M. Cardenas, Nick Dexter

We study the fundamental problem of learning an unknown object from data using a prescribed model class. We introduce a unified framework that accommodates objects in arbitrary Hil…

CS4ML: A general framework for active learning with arbitrary data based on Christoffel functions

Ben Adcock, Juan M. Cardenas, Nick Dexter

We introduce a general framework for active learning in regression problems. Our framework extends the standard setup by allowing for general types of data, rather than merely poin…
