Scaling Experiments in Self-Supervised Cross-Table Representation Learning

no code implementations29 Sep 2023 Maximilian Schambach, Dominique Paul, Johannes S. Otterbach

To analyze the scaling potential of deep tabular representation learning models, we introduce a novel Transformer-based architecture specifically tailored to tabular data and cross-table representation learning by utilizing table-specific tokenizers and a shared Transformer backbone.

Curve Your Enthusiasm: Concurvity Regularization in Differentiable Generalized Additive Models

1 code implementation NeurIPS 2023 Julien Siems, Konstantin Ditschuneit, Winfried Ripken, Alma Lindborg, Maximilian Schambach, Johannes S. Otterbach, Martin Genzel

Generalized Additive Models (GAMs) have recently experienced a resurgence in popularity due to their interpretability, which arises from expressing the target value as a sum of non-linear transformations of the features.

Towards Learning Self-Organized Criticality of Rydberg Atoms using Graph Neural Networks

no code implementations5 Jul 2022 Simon Ohler, Daniel Brady, Winfried Lötzsch, Michael Fleischhauer, Johannes S. Otterbach

Self-Organized Criticality (SOC) is a ubiquitous dynamical phenomenon believed to be responsible for the emergence of universal scale-invariant behavior in many, seemingly unrelated systems, such as forest fires, virus spreading or atomic excitation dynamics.

Learning the Solution Operator of Boundary Value Problems using Graph Neural Networks

1 code implementation28 Jun 2022 Winfried Lötzsch, Simon Ohler, Johannes S. Otterbach

Specifically, we test generalization to meshes with different shapes and superposition of solutions for a different number of inhomogeneities.

Auto-Compressing Subset Pruning for Semantic Image Segmentation

1 code implementation26 Jan 2022 Konstantin Ditschuneit, Johannes S. Otterbach

We show a crucial interplay between providing a high-capacity model at the beginning of training and the compression pressure forcing the model to compress concepts into retained channels.
