FakET: Simulating Cryo-Electron Tomograms with Neural Style Transfer

1 code implementation4 Apr 2023 Pavol Harar, Lukas Herrmann, Philipp Grohs, David Haselbach

A key shortcoming of these supervised learning methods is their need for large training data sets, typically generated from particle models in conjunction with complex numerical forward models simulating the physics of transmission electron microscopes.

Redistributor: Transforming Empirical Data Distributions

1 code implementation25 Oct 2022 Pavol Harar, Dennis Elbrächter, Monika Dörfler, Kory D. Johnson

We present an algorithm and package, Redistributor, which forces a collection of scalar samples to follow a desired distribution.

Towards Robust Voice Pathology Detection

no code implementations13 Jul 2019 Pavol Harar, Zoltan Galaz, Jesus B. Alonso-Hernandez, Jiri Mekyska, Radim Burget, Zdenek Smekal

Automatic objective non-invasive detection of pathological voice based on computerized analysis of acoustic signals can play an important role in early diagnosis, progression tracking and even effective treatment of pathological voices.
