$α$-$β$-Factorization and the Binary Case of Simon's Congruence

no code implementations25 Jun 2023 Pamela Fleischmann, Jonas Höfer, Annika Huch, Dirk Nowotka

In 1991 H\'ebrard introduced a factorization of words that turned out to be a powerful tool for the investigation of a word's scattered factors (also known as (scattered) subwords or subsequences).

On the Self Shuffle Language

no code implementations16 Feb 2022 Pamela Fleischmann, Tero Harju, Lukas Haschke, Jonas Höfer, Dirk Nowotka

The shuffle product \(u\shuffle v\) of two words \(u\) and \(v\) is the set of all words which can be obtained by interleaving \(u\) and \(v\).

m-Nearly k-Universal Words -- Investigating Simon Congruence

no code implementations16 Feb 2022 Pamela Fleischmann, Lukas Haschke, Annika Huch, Annika Mayrock, Dirk Nowotka

We present a full characterisation as well as the index of the congruence for $m=1$.

String Theories involving Regular Membership Predicates: From Practice to Theory and Back

no code implementations15 May 2021 Murphy Berzish, Joel D. Day, Vijay Ganesh, Mitja Kulczynski, Florin Manea, Federico Mora, Dirk Nowotka

Designing an algorithm for the (generally undecidable) satisfiability problem for systems of string constraints requires a thorough understanding of the structure of constraints present in the targeted cases.

Scattered Factor Universality -- The Power of the Remainder

no code implementations19 Apr 2021 Pamela Fleischmann, Sebastian Bernhard Germann, Dirk Nowotka

Scattered factor (circular) universality was firstly introduced by Barker et al. in 2020.

An Empirical Investigation of Randomized Defenses against Adversarial Attacks

1 code implementation12 Sep 2019 Yannik Potdevin, Dirk Nowotka, Vijay Ganesh

In this paper, we propose a scientific evaluation methodology aimed at assessing the quality, efficacy, robustness and efficiency of randomized defenses to protect DNNs against adversarial examples.
