Visual Perception for Humanoid Robots
Abstract:
The ability of humanoid robots to perceive, interpret, and interact with complex dynamic environments is dependent on the development of robust and intelligent visual perception systems. The presentation offers a survey of the visual perception technologies for humanoid robotics. We begin with classical techniques such as Visual Simultaneous Localization and Mapping (V-SLAM), which provide foundational capabilities for environment mapping and pose estimation. The discussion then progresses through modern advancements including self-supervised 3D representation learning, voxel-based spatial modeling, and vision-based reinforcement learning (VRL), all of which enhance the robot’s understanding of its 3D surroundings and its decision-making autonomy. A key distinction between visual perception in humanoid robots and conventional computer vision lies in the embodied, real-time, and action-oriented nature. While standard computer vision systems focus primarily on static tasks such as recognition and classification from fixed sensors, humanoid vision is integrated within a closed-loop sensorimotor architecture. It must function in real-time, fuse data from multiple modalities (e.g. stereo/RGB-D, IMUs, LiDAR), and support continuous state estimation, manipulation, locomotion, and social interaction. The perception system is not merely observational but is tightly coupled with motor control and environmental feedback, demanding higher levels of robustness, 3D spatial understanding, and adaptability. We tackle innovations in deep learning architectures, multi-view sensor fusion, and intrinsically motivated learning strategies. These advancements allow humanoid platforms to perform more reliably in complex tasks such as object manipulation, whole-body control, navigation, and human-robot interaction (HRI). Furthermore, we examine techniques for improving sample efficiency, sim-to-real transfer, and generalization — the key challenges in deploying learned models from simulation to the real world.

International DNA Day Connects Secondary Schools and Universities

pr@uniba.sk — Tue, 13 May 2025 10:19:00 +0200

The event was held on the occasion of International DNA Day, commemorated annually on 25 April. It was organised by the Department of Genetics of the Faculty of Natural Sciences in cooperation with the Institute of Molecular Biomedicine of the Faculty of Medicine of Comenius University Bratislava. FNS hosted a multi-hour programme featuring engaging lectures, interactive workshops and stalls, a discussion club, and competitions in its premises - all centred around the theme of DNA. The event offered an excellent opportunity for secondary school students to expand their knowledge in genetics, molecular biology, and biomedicine. The keynote speaker, Professor Petr Svoboda from the Institute of Molecular Genetics of the Czech Academy of Sciences in Prague, delivered a lecture in the faculty's auditorium, introducing the fascinating world of microRNA and its role in gene expression regulation and DNA protection. The programme also included interactive workshops designed for secondary school students, giving them a chance to conduct hands-on experiments and gain a deeper understanding of modern genetics. They learned about model organisms in genetic research, about how DNA is cleaved and how it is analysed using electrophoresis, followed the scientific process from hypothesis to publication, experienced a demonstration of rapid "mobile" sequencing methods, observed a simulation of cell division and chromosomal errors, and explored the analysis of the human skeleton and its significance in evolution and anthropology. Participants were also able to visit research facilities of the Faculty of Natural Sciences and the Faculty of Medicine, as well as the Slovak Academy of Sciences and the Slovak University of Agriculture, all of which presented their work through posters and interactive booths. A discussion club ran in parallel, offering conversations with PhD students about research, academic studies, and scientific careers. Secondary school student Marína Kiliánová from Bratislava was one of the participants. She will take her final exams in two years and is interested in biology, although she has not yet decided whether she will pursue it at university. "An event like this can really help with making a decision, because you get the chance to go in depth - that is something for which there is no time at school. We also get to try out fully equipped laboratories, which secondary schools don't have," said Marína. Biology teachers also had the opportunity to take part in a workshop titled From DNA Analysis to Treatment, led by Dr Monika Baronová from the John Amos Comenius Lutheran Grammar School in Košice. The course, co-organised with the European Molecular Biology Laboratory in Heidelberg, Germany, aimed to explain the role of DNA analysis in personalised medicine. A total of 23 participants received educational materials including four classroom activities and one extracurricular activity. "We hold DNA Day to bring science closer to young people in a way that is interactive, comprehensible and inspiring. We are very pleased to see growing interest among secondary school students, but the support of their teachers is just as important to us. It is they who can spark an interest in science while students are still at school. That's why we aim to design a programme tailored to their needs as well - we offer new teaching materials, ideas for school activities, and links to current research. Science education is key to our future, and events like DNA Day help build bridges between schools, the university, and the world of science," said a member of the team of organisers Professor Andrea Ševčovičová. The event was initiated by geneticist Vladimír Ferák, and the first DNA Day took place in 2004 to mark the 65th anniversary of the discovery of the DNA structure. It was held in collaboration with a group of enthusiasts led by Peter Celec from the Faculty of Medicine and Andrea Ševčovičová from FNS. This year marked the sixth edition of the event.

Origami expanders Abstract:
We construct the first measure-preserving affine actions with spectral gap on surfaces of arbitrary genus g > 1. We achieve this by finding geometric representatives of multi-twists on origami surfaces. As a major application, we construct new expanders that are coarsely distinct from the classical expanders obtained via the Laplacian as Cayley graphs of finite quotients of a group. Our methods also show that the Margulis expander, and hence the Gabber-Galil expander, is coarsely distinct from the Selberg expander. A joint work with Dawid Kielak (Oxford), Tim de Laat (Kiel), Damian Sawicki (Leuven).

Metric approximations of infinite groups
Abstract:
We discuss various still open questions on approximations of finitely generated groups, focusing on finite-dimensional approximations such as residual finiteness and soficity. We survey our results on the existence and stability of metric approximations. We suggest a few conjectures, e.g. on Gromov hyperbolic groups and their infinite monster limits. The setting is rather general and the involved concepts are transversal to various areas of mathematics. Based on joint works with Liviu Păunescu (Bucharest).

Medical International Day in the Spirit of Cultural Diversity and Solidarity

The event was held under the patronage of Vice-Rector Associate Professor Jozef Tancer and our Dean, Professor Juraj Payer, and was organized by international students from the @SCOIS Club under leadership of Afonso Carracha, student representatives from ŠČAS, and the Study Department, all under the guidance of Vice-Dean Professor Ľudmila Podracká. Special thanks also go to the Institute of Medical Education and Simulations at the Faculty of Medicine and several other theoretical departments that contributed to the organization of the event. The program included a variety of educational activities, such as lectures on AMBOSS, artificial intelligence and its application in medicine or everyday life, and on combining research with clinical practice. Participants also attended a workshop on mental health, as well as practical demonstrations from various medical fields. They had the opportunity to try out laparoscopic techniques, sonography, basic nursing procedures, first aid, and patient’s care. The atmosphere was further enriched by generous snacks and the ever-popular goulash, which helped create a warm and friendly mood throughout the event. We thank everyone who contributed to organizing this event. Medical International Day has become not only a celebration of international spirit but also a place where medicine and humanity come together. We believe this is the beginning of a new tradition, and that Medical International Day, connecting Slovak and international students from around the world, will become an annual event at the Faculty of Medicine.

Data Security Quantification Abstract:
In an era characterized by increasing cyber threats and a growing reliance on digital infrastructure, the imperative to quantify data security has emerged as a critical challenge. This literature review explores the necessity of data security quantification, emphasizing its role in decision-making and optimizing resource allocation. The review synthesizes various methodological models proposed in recent research to address this challenge. Probabilistic and Statistical Modeling Approaches leverage probability distributions and statistical inference. Game Theoretic Approaches model adversarial interactions between attackers and defenders, framing security as a strategic equilibrium. Stochastic Processes and Transition Approaches employ Markov chains to analyze system behavior under uncertainty, capturing temporal and state-dependent risks. Machine Learning and Data-Driven Approaches utilize pattern recognition, anomaly detection, and predictive analytics. Finally, Integrated and Hybrid Approaches combine multiple methodologies to address the limitations of individual techniques, offering frameworks that balance theoretical understanding with practical adaptability. By evaluating the limitations and applicability of these approaches across contexts such as cloud environments, IoT ecosystems, and critical infrastructure, it concludes by identifying gaps in current research, particularly in addressing emerging threats and ensuring robustness in systems.
