Recent Advances in Computer Graphics Vegetation Modeling Abstract:
Trees are among the most visually appealing and complex structures in Nature. They have immeasurable effects on humans as they are an essential part of the atmosphere, but they also have substantial positive value on our well-being. Computer science has attempted to capture and decipher the shape and development of trees for over forty years, with one of the goals being to build tree digital twins – a computer representation that responds to its environment, is simulation-ready, and can be used to answer "what-if" scenarios. This presentation will showcase several recent advances enabled by the deep neural representation of mathematical models of trees, including their development. We will show how tree representations can be learned from data, particularly vegetation capture using LiDAR or single images. We will discuss how L-systems can be learned by the transformer and how a novel deep representation can encapsulate the tree's environmental and growth parameters by learning them from simulated data.  We will also present several recent methods that combine physics to illustrate the dynamics of plant growth and its interaction with the environment.

A Comparative Assessment of the Trustworthiness of Post-Hoc Explanation Approaches for Black Box Models
Abstract:
As AI advances, the need for interpretable machine learning models increases, especially in critical fields like healthcare, cybersecurity, finance, and criminal justice. While black-box models often offer strong predictive performance, their lack of transparency has led to the development of post-hoc explanation methods to clarify decision-making. A key issue, however, is the fidelity of these explanations—how accurately they reflect the model’s behavior. This study introduces a fidelity-focused evaluation framework and evaluates three popular explainers—LIME, SHAP, and Anchor—across various datasets and classifier types (Random Forest, XGBoost, MLP, and SVM). Our analysis shows that while fidelity is moderate generally (not impressive), the effectiveness of explanation methods depends on the model and dataset, with SHAP and Anchor often outperforming LIME. These findings improve our understanding of explanation reliability and offer practical insights for selecting methods to boost interpretability in real-world scenarios.  More information ]]> [FMFI] Prednášky a semináre [FMFI] Kalendár Damas.Gruska@fmph.uniba.sk Wed, 02 Apr 2025 22:34:00 +0200 https://uniba.sk/ Bratislava, 2 April 2025 – Over the past six months, Comenius University Bratislava (CU) has... IEFT Spring Fairs in Turkey. The events took place in three Turkish cities (Izmir, Ankara, and Istanbul) and attracted around 15,000 visitors. This year, 160 universities and educational institutions from 30 countries took part - with CU participating for the very first time. The teams from the International Relations Office and the External Relations Office presented CU's English-language study programmes. Prospective students were particularly interested in programmes in business, natural sciences, and medicine. From 18 to 21 March 2025, we participated in the SRT Eastern Europe Fair in Bulgaria, Romania, and Greece. The events held in Sofia, Bucharest, and Athens attracted around 1,500 students from private secondary schools, many of whom expressed strong interest in studying abroad. The more intimate atmosphere of these fairs allowed for personal conversations with visitors, giving us the opportunity to better present the study options available at CU. The most sought-after programmes were Management and Law, Applied Informatics, Cognitive Science, and social science disciplines such as Psychology and International Relations. International cooperation and knowledge exchange, including global citizenship, were the main themes of the prestigious APAIE 2025 conference held in New Delhi, India (APAIE stands for Asia-Pacific Association for International Education), one of the leading global events in the field of higher education. This year's edition took place from 24 to 28 March 2025. Slovakia was represented by a delegation from the Ministry of Education, accompanied by representatives from 14 public universities, including CU. The final event of the month was the Saló de l'Ensenyament in Barcelona, Spain, which took place from 26 to 30 March 2025 at the Montjuïc exhibition grounds. This event in the Catalan capital saw a record turnout of more than 107,000 visitors. CU's stand attracted particular interest from students considering study programmes in Management, Social Sciences, and Medicine in English. Visitors appreciated the information about Bratislava as a safe and attractive city for students, as well as the vibrant extracurricular life CU offers. We are confident that these intense months of international outreach of CU will bear fruit, and that we will see more students from across the world - including Turkey, Bulgaria, Romania, Greece, Spain, and India - at our September enrolment. CU's participation in the international fairs and at the conference was financially supported by the Recovery and Resilience Plan of the Slovak Republic under the call "Support for projects promoting Slovak higher education institutions abroad."

The event brought together experts from the field of law and cybersecurity to discuss the prevention of cyber-attacks, the handling of incidents and their legal implications. Current threats and preventive measures The opening part of the seminar was presented by Tomáš Hettych from the Cyber Security Competence and Certification Centre (KCCKB) and Jaroslav Ďurovka, Director of the National Cyber Security Centre of the National Security Authority (NBÚ). In their presentations, they focused on current cyber threats and preventive measures that organisations can take to increase their resilience. Milan Pikula, Director of SK-CERT, presented the current statistics of ransomware attacks and pointed to the growing trend of sophisticated cyber threats that threaten not only companies but also the public sector. Criminal liability in cyber attacks The issue of legal liability for cyber incidents was also an important part of the discussion. Prof. JUDr. Jozef Čentéš, DrSc., and JUDr. Michal Rampášek analysed the legal aspects of cybercrime and stressed the importance of effective criminal prosecution of the perpetrators of these attacks. Collaboration as the key to better cybersecurity The seminar stressed the importance of cooperation between academic community, state institutions and practitioners in addressing cyber security challenges. Participants acknowledged the need to raise awareness of cyber threats and to strengthen the legislative framework to address them more effectively. The event showed that cybersecurity is a dynamic area that requires constant dialogue between practitioners and legislative drafters. The Faculty of Law of CU once again demonstrated its role as a platform for the discussion of current social and legal challenges. ]]> [PraF] Titulka - úzke novinky - z uniba.sk [PraF] EN Titulka - úzke novinky Wed, 02 Apr 2025 10:26:00 +0200 https://uniba.sk/ Tuesday 8.4.2025 at 14:00, Lecture room F2/125 Mgr.

Entanglement in Tensor Networks
Abstract:
Tensor Networks are special classes of variational quantum states typically applied to study strongly correlated many-body systems. They were developed to calculate ground and excited states of higher-dimensional systems originating in the one-dimensional matrix product states (equivalent to the density matrix renormalization group). We aim to explain their mathematical background rooted in maximizing quantum entanglement. We show the main principles in the simplest examples. Due to a so-called quantum-classical correspondence (imaginary time evolution), we analyze two identical representations of the Tensor Networks: 1) the vertex representation (commonly used in the quantum states) and 2) the weight representation (well-known from classical statistical mechanics). We explain two-dimensional classical spin models exhibiting equivalent partition functions. Although the equivalency of all observables and correlations for both representations, entanglement entropy is always lower for the vertex representation of the Tensor Networks for finite and infinite systems, irrespective of the spin-lattice model, the number of spin degrees of freedom, and the underlying lattice geometry. We consider various types of tensor networks to investigate why the discrepancy persists within all phase-transition types generated in a wide range of spin Hamiltonians. ]]> [FMFI] Prednášky a semináre [FMFI] Kalendár Peter.Matak@fmph.uniba.sk Tue, 01 Apr 2025 14:29:00 +0200
