Signal Is Harder To Learn Than Bias: Debiasing with Focal Loss

1 code implementation31 May 2023 Moritz Vandenhirtz, Laura Manduchi, Ričards Marcinkevičs, Julia E. Vogt

We propose Signal is Harder (SiH), a variational-autoencoder-based method that simultaneously trains a biased and unbiased classifier using a novel, disentangling reweighting scheme inspired by the focal loss.

Anomaly Detection in Echocardiograms with Dynamic Variational Trajectory Models

1 code implementation30 Jun 2022 Alain Ryser, Laura Manduchi, Fabian Laumer, Holger Michel, Sven Wellmann, Julia E. Vogt

The introduced method takes advantage of the periodic nature of the heart cycle to learn three variants of a variational latent trajectory model (TVAE).

Learning Group Importance using the Differentiable Hypergeometric Distribution

1 code implementation3 Mar 2022 Thomas M. Sutter, Laura Manduchi, Alain Ryser, Julia E. Vogt

We introduce reparameterizable gradients to learn the importance between groups and highlight the advantage of explicitly learning the size of subsets in two typical applications: weakly-supervised learning and clustering.

Deep Conditional Gaussian Mixture Model for Constrained Clustering

1 code implementation NeurIPS 2021 Laura Manduchi, Kieran Chin-Cheong, Holger Michel, Sven Wellmann, Julia E. Vogt

Constrained clustering has gained significant attention in the field of machine learning as it can leverage prior information on a growing amount of only partially labeled data.

A Probabilistic Approach to Constrained Deep Clustering

no code implementations1 Jan 2021 Laura Manduchi, Kieran Chin-Cheong, Holger Michel, Sven Wellmann, Julia E Vogt

Clustering with constraints has gained significant attention in the field of semi-supervised machine learning as it can leverage partial prior information on a growing amount of unlabelled data.

DPSOM: Deep Probabilistic Clustering with Self-Organizing Maps

2 code implementations3 Oct 2019 Laura Manduchi, Matthias Hüser, Julia Vogt, Gunnar Rätsch, Vincent Fortuin

We show that DPSOM achieves superior clustering performance compared to current deep clustering methods on MNIST/Fashion-MNIST, while maintaining the favourable visualization properties of SOMs.

Variational pSOM: Deep Probabilistic Clustering with Self-Organizing Maps

no code implementations25 Sep 2019 Laura Manduchi, Matthias Hüser, Gunnar Rätsch, Vincent Fortuin

There are very performant deep clustering models on the one hand and interpretable representation learning techniques, often relying on latent topological structures such as self-organizing maps, on the other hand.
