Tackling the computer overuse as a cause of chronic musculoskeletal disorders with the concept of a tangible personal persuasive avatar
(Wydawnictwo Politechniki Łódzkiej, 2015) Kosiński, Tomasz; Grzelak, Piotr; Kucharski, Przemysław; Romanowski, Andrzej; Chaniecki, Zbigniew
[...] The presented work, introducing a prototype of interactive avatars persuasive system into employees' natural workplaces, provided an opportunity of insight into human behavior at work and the possible problems to the company's productivity. The results of evaluation stage confirmed the impact that such a real avatar has on the user and revealed system improvement areas. It is intended to adjust robot's operations and sound persuasion stage. The evaluation phase is to be reviewed within the interdisciplinary team in order to provide the most accurate assessment methods. It was proven that human behavior can be changed in an unobtrusive way, without the need of announcing the official regulations, effectively.[...]
Towards Detection of Unknown Polymorphic Patterns Using Prior Knowledge
(Wydawnictwo Politechniki Łódzkiej, 2023) Kucharski, Przemysław; Ślot, Krzysztof
The presented paper proposes a novel approach for detecting unknown polymorphic patterns in sequences composed of random symbols and of known polymorphic patterns. We propose to represent rules that drive pattern generation as regular expressions. To detect unknown patterns, we first incorporate knowledge on known rules into a Convolutional Autoencoder (CAE), then we train the CAE with additional objective to prevent weights from learning the already known patterns. Analysis of training results provides statistically significant information on presence or absence of polymorphic patterns that were not previously known.
