On the Impact of Stable Ranks in Deep Nets

no code implementations5 Oct 2021 Bogdan Georgiev, Lukas Franken, Mayukh Mukherjee, Georgios Arvanitidis

A recent line of work has established intriguing connections between the generalization/compression properties of a deep neural network (DNN) model and the so-called layer weights' stable ranks.

Natural Questions

A prior-based approximate latent Riemannian metric

no code implementations9 Mar 2021 Georgios Arvanitidis, Bogdan Georgiev, Bernhard Schölkopf

In this work we propose a surrogate conformal Riemannian metric in the latent space of a generative model that is simple, efficient and robust.

Quantum Circuit Evolution on NISQ Devices

no code implementations23 Dec 2020 Lukas Franken, Bogdan Georgiev, Sascha Mücke, Moritz Wolter, Raoul Heese, Christian Bauckhage, Nico Piatkowski

The results provide intuition on how randomized search heuristics behave on actual quantum hardware and lay out a path for further refinement of evolutionary quantum gate circuits.

Generative Deep Learning Techniques for Password Generation

no code implementations10 Dec 2020 David Biesner, Kostadin Cvejoski, Bogdan Georgiev, Rafet Sifa, Erik Krupicka

Password guessing approaches via deep learning have recently been investigated with significant breakthroughs in their ability to generate novel, realistic password candidates.

Recurrent Point Review Models

1 code implementation10 Dec 2020 Kostadin Cvejoski, Ramses J. Sanchez, Bogdan Georgiev, Christian Bauckhage, Cesar Ojeda

Specifically, we use the dynamic representations of recurrent point process models, which encode the history of how business or service reviews are received in time, to generate instantaneous language models with improved prediction capabilities.
