Harnessing Orthogonality to Train Low-Rank Neural Networks

no code implementations16 Jan 2024 Daniel Coquelin, Katharina Flügel, Marie Weiel, Nicholas Kiefer, Charlotte Debus, Achim Streit, Markus Götz

This study explores the learning dynamics of neural networks by analyzing the singular value decomposition (SVD) of their weights throughout training.

Feed-Forward Optimization With Delayed Feedback for Neural Networks

1 code implementation26 Apr 2023 Katharina Flügel, Daniel Coquelin, Marie Weiel, Charlotte Debus, Achim Streit, Markus Götz

Backpropagation has long been criticized for being biologically implausible, relying on concepts that are not viable in natural learning processes.

Biologically-plausible Training Computational Efficiency

Massively Parallel Genetic Optimization through Asynchronous Propagation of Populations

1 code implementation20 Jan 2023 Oskar Taubert, Marie Weiel, Daniel Coquelin, Anis Farshian, Charlotte Debus, Alexander Schug, Achim Streit, Markus Götz

We present Propulate, an evolutionary optimization algorithm and software package for global optimization and in particular hyperparameter search.

Learning Tree Structures from Leaves For Particle Decay Reconstruction

1 code implementation31 Aug 2022 James Kahn, Ilias Tsaklidis, Oskar Taubert, Lea Reuter, Giulio Dujany, Tobias Boeckh, Arthur Thaller, Pablo Goldenzweig, Florian Bernlochner, Achim Streit, Markus Götz

In the case of high-energy particle physics, a particle decay forms a hierarchical tree structure of which only the final products can be observed experimentally, and the large combinatorial space of possible trees makes an analytic solution intractable.

HyDe: The First Open-Source, Python-Based, GPU-Accelerated Hyperspectral Denoising Package

1 code implementation14 Apr 2022 Daniel Coquelin, Behnood Rasti, Markus Götz, Pedram Ghamisi, Richard Gloaguen, Achim Streit

Furthermore, we present a method for training DNNs for denoising HSIs which are not spatially related to the training dataset, i. e., training on ground-level HSIs for denoising HSIs with other perspectives including airborne, drone-borne, and space-borne.

HeAT -- a Distributed and GPU-accelerated Tensor Framework for Data Analytics

1 code implementation27 Jul 2020 Markus Götz, Daniel Coquelin, Charlotte Debus, Kai Krajsek, Claudia Comito, Philipp Knechtges, Björn Hagemeier, Michael Tarnawa, Simon Hanselmann, Martin Siggel, Achim Basermann, Achim Streit

With HeAT, it is possible for a NumPy user to take full advantage of their available resources, significantly lowering the barrier to distributed data analysis.
