Hierarchical clustering with maximum density paths and mixture models

1 code implementation19 Mar 2025 Martin Ritzert, Polina Turishcheva, Laura Hansel, Paul Wollenhaupt, Marissa Weis, Alexander Ecker

Hierarchical clustering is an effective and interpretable technique for analyzing structure in data, offering a nuanced understanding by revealing insights at multiple scales and resolutions.

FLASHμ: Fast Localizing And Sizing of Holographic Microparticles

no code implementations14 Mar 2025 Ayush Paliwal, Oliver Schlenczek, Birte Thiede, Manuel Santos Pereira, Katja Stieger, Eberhard Bodenschatz, Gholamhossein Bagheri, Alexander Ecker

Reconstructing the 3D location and size of microparticles from diffraction images - holograms - is a computationally expensive inverse problem that has traditionally been solved using physics-based reconstruction methods.

Reproducibility of predictive networks for mouse visual cortex

no code implementations18 Jun 2024 Polina Turishcheva, Max Burg, Fabian H. Sinz, Alexander Ecker

Such weight vectors, which can be thought as embeddings of neuronal function, have been proposed to define functional cell types via unsupervised clustering.

Probabilistic Neural Transfer Function Estimation with Bayesian System Identification

no code implementations11 Aug 2023 Nan Wu, Isabel Valera, Fabian Sinz, Alexander Ecker, Thomas Euler, Yongrong Qiu

While deep neural network models have demonstrated excellent power on neural prediction, they usually do not provide the uncertainty of the resulting neural representations and derived statistics, such as the stimuli driving neurons optimally, from in silico experiments.

Variational Inference

Assessing out-of-domain generalization for robust building damage detection

1 code implementation20 Nov 2020 Vitus Benson, Alexander Ecker

Such models operate in a multi-domain setting: every disaster is inherently different (new geolocation, unique circumstances), and models must be robust to a shift in distribution between disaster imagery available for training and the images of the new event.

Neurometric function analysis of population codes

no code implementations NeurIPS 2009 Philipp Berens, Sebastian Gerwinn, Alexander Ecker, Matthias Bethge

In this way, we provide a new rigorous framework for assessing the functional consequences of noise correlation structures for the representational accuracy of neural population codes that is in particular applicable to short-time population coding.
