Accelerating hyperbolic t-SNE

no code implementations23 Jan 2024 Martin Skrodzki, Hunter van Geffen, Nicolas F. Chaves-de-Plaza, Thomas Höllt, Elmar Eisemann, Klaus Hildebrandt

The need to understand the structure of hierarchical or high-dimensional data is present in a variety of fields.

Dimensionality Reduction

Tuning the perplexity for and computing sampling-based t-SNE embeddings

no code implementations29 Aug 2023 Martin Skrodzki, Nicolas Chaves-de-Plaza, Klaus Hildebrandt, Thomas Höllt, Elmar Eisemann

Further, we show how this approach speeds up the computation and increases the quality of the embeddings.

Parametrizing Product Shape Manifolds by Composite Networks

1 code implementation28 Feb 2023 Josua Sassen, Klaus Hildebrandt, Martin Rumpf, Benedikt Wirth

Parametrizations of data manifolds in shape spaces can be computed using the rich toolbox of Riemannian geometry.

Efficient Neural Network

ProtoFold Neighborhood Inspector

no code implementations17 Oct 2022 Nicolas F. Chaves-de-Plaza, Klaus Hildebrandt, Anna Vilanova

Post-translational modifications (PTMs) affecting a protein's residues (amino acids) can disturb its function, leading to illness.

DeltaConv: Anisotropic Operators for Geometric Deep Learning on Point Clouds

1 code implementation16 Nov 2021 Ruben Wiersma, Ahmad Nasikun, Elmar Eisemann, Klaus Hildebrandt

Learning from 3D point-cloud data has rapidly gained momentum, motivated by the success of deep learning on images and the increased availability of 3D~data.

3D Part Segmentation 3D Point Cloud Classification +2

Comparing Bayesian Models for Organ Contouring in Head and Neck Radiotherapy

1 code implementation1 Nov 2021 Prerak Mody, Nicolas Chaves-de-Plaza, Klaus Hildebrandt, Rene van Egmond, Huib de Ridder, Marius Staring

However, in a QA context, a model should also have high uncertainty in inaccurate regions and low uncertainty in accurate regions.

CNNs on Surfaces using Rotation-Equivariant Features

1 code implementation SIGGRAPH 2020 Ruben Wiersma, Elmar Eisemann, Klaus Hildebrandt

We propose a network architecture for surfaces that consists of vector-valued, rotation-equivariant features.
