Differentiable Random Partition Models

1 code implementation NeurIPS 2023 Thomas M. Sutter, Alain Ryser, Joram Liebeskind, Julia E. Vogt

Partitioning a set of elements into an unknown number of mutually exclusive subsets is essential in many machine learning problems.

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).

Anomaly Detection

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.
