Learning Objective-Specific Active Learning Strategies with Attentive Neural Processes

1 code implementation11 Sep 2023 Tim Bakker, Herke van Hoof, Max Welling

In this work, we propose a novel LAL method for classification that exploits symmetry and independence properties of the active learning problem with an Attentive Conditional Neural Process model.

E-Valuating Classifier Two-Sample Tests

no code implementations24 Oct 2022 Teodora Pandeva, Tim Bakker, Christian A. Naesseth, Patrick Forré

Compared to $p$-values-based tests, tests with E-values have finite sample guarantees for the type I error.

On learning adaptive acquisition policies for undersampled multi-coil MRI reconstruction

1 code implementation30 Mar 2022 Tim Bakker, Matthew Muckley, Adriana Romero-Soriano, Michal Drozdzal, Luis Pineda

Most current approaches to undersampled multi-coil MRI reconstruction focus on learning the reconstruction model for a fixed, equidistant acquisition trajectory.

Back to Basics: Deep Reinforcement Learning in Traffic Signal Control

1 code implementation15 Sep 2021 Sierk Kanis, Laurens Samson, Daan Bloembergen, Tim Bakker

In this paper we revisit some of the fundamental premises for a reinforcement learning (RL) approach to self-learning traffic lights.

Experimental design for MRI by greedy policy search

2 code implementations NeurIPS 2020 Tim Bakker, Herke van Hoof, Max Welling

In today's clinical practice, magnetic resonance imaging (MRI) is routinely accelerated through subsampling of the associated Fourier domain.
