Literature Review and Research Directions in Trustworthy AI for Medical Imaging
Abstract:
Artificial intelligence has become increasingly important in medical imaging applications such as image segmentation, classification, localization, and computer-assisted diagnosis. Although recent deep learning approaches have achieved high performance across multiple medical imaging tasks, several challenges still limit their reliability and broader clinical adoption. Current research highlights important issues related to explainability, robustness, annotation quality, model generalization, and trustworthiness in AI-assisted medical systems. This presentation summarizes the initial literature review conducted in the area of trustworthy AI for medical imaging. The review focused on understanding common deep learning workflows used in medical image analysis, including preprocessing, region of interest localization, segmentation, classification, and evaluation methodologies. Particular attention was given to explainable AI approaches, segmentation architectures such as U-Net and nnU-Net, transformer-based models, and hybrid deep learning frameworks applied in CT and CBCT imaging studies. The reviewed literature indicates that while many existing models report high quantitative performance using metrics such as Dice score, IoU, and classification accuracy, several open research problems remain insufficiently addressed. These include limited dataset availability, annotation inconsistency, lack of robustness across different imaging conditions, and limited validation of explainability methods for real clinical use. Based on these observations, the presentation outlines possible future research directions related to trustworthy and explainable AI systems in medical imaging, with a particular interest in model reliability, preprocessing workflows, segmentation robustness, and interpretable deep learning methods for clinical applications.  More information Youtube channel ]]> [FMFI] Prednášky a semináre [FMFI] Kalendár Damas.Gruska@fmph.uniba.sk Tue, 19 May 2026 12:42:00 +0200 https://www.fm.uniba.sk//en/news-detail/browse/16/back_to_page/aktuality-35/article/seminar-z-teorie-grafov-matus-matok-2152026/ Thursday 21.5.2026 at 9:50, Lecture room M 213 Matúš Matok:
Lonely edges in cubic graphs Abstract:
The notion of a perfect matching, i.e., a 1-regular spanning subgraph—a set of disjoint edges covering all vertices of a given graph—is a well studied subject in graph theory. Already in 1891, Petersen proved that each edge of a bridgeless cubic graph can be covered by a perfect matching. We say that an edge e is matching double covered if there exist two distinct perfect matchings containing e. Otherwise, e is said to be lonely. If all edges of a graph are matching double covered, so is the graph. A graph G is Klee if it is the complete graph on 4 vertices or it is obtained from another Klee graph by the operation of replacing a vertex with a triangle. This operation is denoted as G ↑ v for some vertex v ∈ V(G) of G. All Klee graphs are therefore 3-connected and planar. The classes of Klee graphs with more than three lonely edges have been characterized by Goedgebeur [1] et al. Wedefineanauxiliary structure called a decomposition tree which is a well-defined object with respect to a lonely edge e ∈ E(G) of a graph G. With the help of decomposition trees, we can argue about loneliness of e in G ↑ v for all vertices of G, giving us both positive and negative certificates of this status. This allows us to characterize all graphs with one or two lonely edges, hence completing the characterization of cubic graphs with lonely edges.  References:

Topological neutrinos and their cosmic consequences Abstract:
In this seminar, we present a novel way to reinterpret the neutrino. Our main focus is on the topological quantity associated with the electroweak anomaly. Integrating out the gauge and fermion fields, except or the neutrinos, we are left with an effective vertex similar to the 'tHooft vertex for quarks. Then, using the gap equation, we generate the neutrino condensate, which, in turn, determines the Majorana mass of neutrinos. The model's predictions are staggering: it provides a clear physical explanation for neutrino mass, mixing, and $CP$ violation and, on the cosmological scale, yields deviations from the established result. Moreover, the model provides a clear identity for neutrinos: they are Majorana particles, and their nature is enforced by the electroweak vacuum’s topology. These topological neutrinos have very specific cosmic consequences such as a first order topological phase transition, softening the initial quark gluon plasma in the early Universe this deviation from the standard equation of state, and more importantly we establish a connection between dark energy and the dineutrino condensate. The procedure is quite straightforward: we take the neutrino condensate and simply plug it into the Einstein Field Equations. Then we discover the relation between dark energy neutrino mass, which were already hypothesised, and instanton suppression, which we use to show that the three-flavour generation of the Universe is a topological necessity and provides a reason for the stability of it. ]]> [FMFI] Prednášky a semináre [FMFI] Kalendár Peter.Matak@fmph.uniba.sk Mon, 18 May 2026 21:35:00 +0200 http://www.fpharm.uniba.sk/en/about-the-faculty/current/ [FaF] Titulka - slider Thu, 20 Feb 2020 17:00:00 +0100
