Using and Abusing Equivariance

no code implementations22 Aug 2023 Tom Edixhoven, Attila Lengyel, Jan van Gemert

In this paper we show how Group Equivariant Convolutional Neural Networks use subsampling to learn to break equivariance to their symmetries.

Domain Adaptation for Rare Classes Augmented with Synthetic Samples

no code implementations23 Oct 2021 Tuhin Das, Robert-Jan Bruintjes, Attila Lengyel, Jan van Gemert, Sara Beery

While domain adaptation is generally applied on completely synthetic source domains and real target domains, we explore how domain adaptation can be applied when only a single rare class is augmented with simulated samples.

Zero-Shot Day-Night Domain Adaptation with a Physics Prior

1 code implementation ICCV 2021 Attila Lengyel, Sourav Garg, Michael Milford, Jan C. van Gemert

The traditional domain adaptation setting is to train on one domain and adapt to the target domain by exploiting unlabeled data samples from the test set.

Exploiting Learned Symmetries in Group Equivariant Convolutions

1 code implementation9 Jun 2021 Attila Lengyel, Jan C. van Gemert

Group Equivariant Convolutions (GConvs) enable convolutional neural networks to be equivariant to various transformation groups, but at an additional parameter and compute cost.

Evaluating the performance of the LIME and Grad-CAM explanation methods on a LEGO multi-label image classification task

no code implementations4 Aug 2020 David Cian, Jan van Gemert, Attila Lengyel

In this paper, we run two methods of explanation, namely LIME and Grad-CAM, on a convolutional neural network trained to label images with the LEGO bricks that are visible in them.
