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.

RANRAC: Robust Neural Scene Representations via Random Ray Consensus

no code implementations15 Dec 2023 Benno Buschmann, Andreea Dogaru, Elmar Eisemann, Michael Weinmann, Bernhard Egger

We demonstrate the compatibility and potential of our solution for both photo-realistic robust multi-view reconstruction from real-world images based on neural radiance fields and for single-shot reconstruction based on light-field networks.

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.

Template-free Articulated Neural Point Clouds for Reposable View Synthesis

1 code implementation NeurIPS 2023 Lukas Uzolas, Elmar Eisemann, Petr Kellnhofer

We demonstrate the versatility of our representation on a variety of articulated objects from common datasets and obtain reposable 3D reconstructions without the need of object-specific skeletal templates.

Incorporating Texture Information into Dimensionality Reduction for High-Dimensional Images

1 code implementation18 Feb 2022 Alexander Vieth, Anna Vilanova, Boudewijn Lelieveldt, Elmar Eisemann, Thomas Höllt

In this paper, we present a method for incorporating spatial neighborhood information into distance-based dimensionality reduction methods, such as t-Distributed Stochastic Neighbor Embedding (t-SNE).

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.

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.

How to Manipulate CNNs to Make Them Lie: the GradCAM Case

no code implementations25 Jul 2019 Tom Viering, Ziqi Wang, Marco Loog, Elmar Eisemann

This illustrates that GradCAM cannot explain the decision of every CNN and provides a proof of concept showing that it is possible to obfuscate the inner workings of a CNN.

GPGPU Linear Complexity t-SNE Optimization

1 code implementation28 May 2018 Nicola Pezzotti, Julian Thijssen, Alexander Mordvintsev, Thomas Hollt, Baldur van Lew, Boudewijn P. F. Lelieveldt, Elmar Eisemann, Anna Vilanova

The t-distributed Stochastic Neighbor Embedding (tSNE) algorithm has become in recent years one of the most used and insightful techniques for the exploratory data analysis of high-dimensional data.

Approximated and User Steerable tSNE for Progressive Visual Analytics

no code implementations5 Dec 2015 Nicola Pezzotti, Boudewijn P. F. Lelieveldt, Laurens van der Maaten, Thomas Höllt, Elmar Eisemann, Anna Vilanova

Progressive Visual Analytics aims at improving the interactivity in existing analytics techniques by means of visualization as well as interaction with intermediate results.
