NASLOV: Comparative Analysis of VR and Traditional Simulators in Anti-Aircraft Training
-----------------------------------------------------------------------------------------------------------------------
POVZETEK:
The study aims to measure attitude processes when using simulators and subjective experiences after use by comparing a VR-based immersive simulator and a classic non-immersive simulator. The target groups are the conscripts in the Parola Armored Brigade of the Finnish Defense Forces, who will receive training in using an anti-aircraft machine gun with the help of virtual reality. Both simulators highlighted commendable traits, such as prompt responsiveness to user actions and awareness of control devices. The VR simulator's propensity to induce more pronounced simulator sickness symptoms occurred similarly in both simulators, suggesting common physiological responses across different simulator types. Interestingly, participants in the VR simulator found it easier to control events and manipulate objects, leading to better engagement than in real-life scenarios. These findings illuminate the advantages and limitations of VR training with augmented cues, offering valuable insights for refinement and future research endeavors.

------------------------------------------------------------
POVZETEK:
Veliki jezikovni modeli (LLM) so revolucionarizirali obdelavo naravnega jezika z izkoriščanjem obsežnih podatkovnih nizov in arhitektur globokega učenja za generiranjem besedila, odgovarjanjem na vprašanja in izvajanjem kompleksnega sklepanja. Ta seminar raziskuje osnovne mehanizme LLM, vključno z njihovo arhitekturo in metodami usposabljanja, pri čemer izpostavlja naraščajoče število primerov njihove uporabe na različnih področjih. Konkretno se obravnavajo aplikacije LLM v medicini za pomoč pri diagnozi in generiranju medicinske literature, v robotiki za izboljšanje interakcije med človekom in robotom ter v kodiranju za avtomatizacijo razvoja programske opreme. Poudarjeni so tudi izzivi, povezani z ocenjevanjem modelov, vključno z obsegom znanja in razširljivostjo, ter potencialne prihodnje smeri za izboljšanje zmogljivosti LLM.

NASLOV: Interactive and Robust Mesh Booleans
------------------------------------------------------------------
POVZETEK:
Boolean operations are among the most used paradigms to create and edit digital shapes. Despite being conceptually simple, the computation of mesh Booleans is notoriously challenging. The main issues come from numerical approximations that make the detection and processing of intersection points inconsistent and unreliable, exposing implementations based on floating-point arithmetic to many kinds of failure. Numerical methods based on rational numbers or exact geometric predicates have the needed robustness guarantees that are achieved at the cost of increased computation times that, as of today, have always restricted the use of robust mesh Booleans to offline applications. In this seminar, I will briefly summarize the results obtained in three recent articles on the topic, which have enabled us to develop an algorithm for Boolean operations with robustness guarantees, capable of operating at interactive frame rates on meshes with up to 200K triangles.

NASLOV: Finding the number of inequivalent arithmetic expressions on n variables
-----------------------------------------------------------------------------------------------------------------
POVZETEK:
Given n distinct formal variables, in how many ways can we use them to construct different arithmetic expressions? An expression tree is a rooted tree whose internal nodes correspond to some operations to be performed, while its leaves are formal variables. Here, we deal with the expression trees such that the only allowed operations are the four standard arithmetic operations (addition, subtraction, multiplication and division) together with, optionally, additive inversion. We consider two expressions to be equivalent if their expression trees yield the same formal expression. To begin, we provide certain theoretical results concerning the equivalence of arithmetic expressions. Afterwards, we disclose a Θ(n^2) algorithm that computes the number of inequivalent arithmetic expressions on n distinct variables. The algorithm covers both the case when the unary operation of additive inversion is allowed and when it is not.
(This is a joint work with Ivan Stošić and Žarko Ranđelović.)

NASLOV: A Data-Driven Approach for the Analysis of Ridership Fluctuations in Transit Systems
--------------------------------------------------------------------------------------------------------------------------------
POVZETEK:
This seminar explores a data-driven approach to analyzing ridership fluctuations in public transportation systems, especially during pandemics. It focuses on identifying critical components within urban transit systems, by employing agent-based simulations and graph analytics techniques. Key findings reveal specific transit stops and routes that are highly sensitive to changes in demand, often serving as bottlenecks or high-risk areas for the spread of infectious diseases.
