Latent SDEs on Homogeneous Spaces

1 code implementation NeurIPS 2023 Sebastian Zeng, Florian Graf, Roland Kwitt

We consider the problem of variational Bayesian inference in a latent variable model where a (possibly complex) observed stochastic process is governed by the solution of a latent stochastic differential equation (SDE).

On Measuring Excess Capacity in Neural Networks

1 code implementation16 Feb 2022 Florian Graf, Sebastian Zeng, Bastian Rieck, Marc Niethammer, Roland Kwitt

We study the excess capacity of deep networks in the context of supervised classification.

Dissecting Supervised Contrastive Learning

1 code implementation17 Feb 2021 Florian Graf, Christoph D. Hofer, Marc Niethammer, Roland Kwitt

Minimizing cross-entropy over the softmax scores of a linear map composed with a high-capacity encoder is arguably the most popular choice for training neural networks on supervised learning tasks.

Topologically Densified Distributions

1 code implementation ICML 2020 Christoph D. Hofer, Florian Graf, Marc Niethammer, Roland Kwitt

We study regularization in the context of small sample-size learning with over-parameterized neural networks.

Graph Filtration Learning

1 code implementation ICML 2020 Christoph D. Hofer, Florian Graf, Bastian Rieck, Marc Niethammer, Roland Kwitt

We propose an approach to learning with graph-structured data in the problem domain of graph classification.
