Statistical learning from complex data for better understanding and decision making in neurobiology and medicine
Abstract: 
In domains of medicine and neuroscience, there is an increasing number of complex datasets. They have potential to answer questions that have not been answered yet. However, the growth of the new datasets needs to be matched with growth of appropriate flexible statistical learning methods. One of the frameworks that is appropriate is a so-called model-based statistical learning methodology. The key idea is to build a complex model, that captures the complexity of the data, and then do use this model for learning: to do inference about disease or biology or to do a prediction. Here, we first bring four typical complex data scenarios to illustrate the rich spectrum of problems that complex data can bring. The first scenario is from neuroscience, were we studied spiking behaviour of hippocampal neurons of monkey which was learning a location-scene association task. These high-frequency data (every 1ms) were studied to understand how the neuron was involved in the monkey’s learning. In the second scenario we use data from general practices, linked with hospital records, to find out if there is an increased risk of oesophageal cancer in those who take bisphosphonates to prevent or slow down osteoporosis. In the third scenario, we use longitudinally collected data from epilepsy patients, from several visits, and we aimed to predict as early as possible, which patient is in remission. In the last illustrating scenario, high dimensional spatial data: the images of retina. Our aim was to find out how to learn about risk factors of retinal diseases, as well as how to detect diseases. We will show how we used statistical models to formulate the problem of data complexity, and how we then used the models for statistical learning: to test statistical hypotheses or to detect disease. In the hippocampus neuron, we developed and implemented algorithm that learns from the fitted model, we showed how we learned about neurons’ role in monkey’s behaviour, we then extended our work to develop novel signal-to-noise ratio for neurons. We will show how we approached the problem of confounding and how found new risk factor for oesophageal cancer. We will share experience of how we developed dynamic procedure for monitoring of epilepsy patients, and how we made it safe. Finally, we will discuss our work on statistical spatial models of retina, how this leads to higher power of hypothesis testing, and to high accuracy of disease detection, comparable to machine learning methods. We will also show how the illustrating examples led to further research and how these seemingly different scenarios are interlinked. We also discuss future avenues for research to harness complex datasets.  Bio

Self-organization in multi-lane traffic model
Abstract: 
Self-organization is a property of many systems in biology, sociology, economics or telecommunications. Conflicts within the system are resolved by moving to other territories, networks and channels. We study self-organization in a model stochastic system of individuals moving on a circular track. The model is a modification of a system studied by Goldsztein (2017, 2020) but it cannot be treated by the same method as it changes the number of states from finite to infinity. We prove the certainty of self-organization in the system. Quite unexpectedly, the model leads to generalizations and connections with other problems. This is a joint work with Kamila Friedrichova, Jan Glut (Bc. students).

The Paper summarises the latest, most significant medical advances in Slovak and international research of testicular tumours. Our team of Slovak medical specialists and researchers is world-renowned and regularly cooperates in international expert groups, presenting their discoveries in journals and at conferences. Our experts from the Faculty of Medicine of Comenius University significantly contributed to the knowledge of biomarkers for a more accurate prognosis of this disease. They mapped the effects of the immune system on the disease, and discovered that chemotherapy resistance is caused by malfunctions in DNA repair in the tumour and tumour stem cells. The findings helped to better identify patients with a very good or a very poor prognosis and led to several original clinical trials involving innovative drugs. Our researchers also contributed to the detection of several types of delayed effects of treatment in cured patients and are beginning to reveal the mechanisms of such toxicity at the molecular level. It turns out that disruption of the intestinal microbiome during treatment, among other reasons, can play an important role, stimulating further studies in the future. Doctors and researchers have been systematically treating testicular tumours since the mid-1960s. The most important step towards the cure of testicular cancer was the discovery of the antitumour effect of cisplatin and the subsequent use of cisplatin in combination with other chemotherapy drugs in those patients whose prognosis was ‘incurable’. Treatment regimens using cisplatin have successfully caught on worldwide. „Today's form of successful testicular cancer treatment is based on the improvement of chemotherapy treatment methods and the improvement of surgical techniques for the removal of residual metastases in the complex anatomical environment of the abdominal cavity, lungs, liver, brain or bones,“ explains Michal Chovanec from the 2nd. oncology clinic of the Medical Faculty and NOÚ. Equally important are innovative diagnostic methods using imaging, such as computer tomography or magnetic resonance, as well as the discovery of new molecular markers. These help to improve our understanding of the biological nature of this disease and to search for innovative drugs for the small group of patients who do not respond well to salvage chemotherapy and are dying of the disease. The British Medical Journal, where the study was published, is a world leader in medicine, and one of the oldest journals in this field. „It is a tremendous honour for me to provide my research perspective on today's testicular oncology. I believe that initiatives like this one can publicise and deepen our passion for medicine and for the discovery of better and safer treatments for our patients, not only those with testicular cancer,“ says lead author Michal Chovanec from CU. ]]> [RUK] Titulka - úzke novinky [RUK] Tlačové správy [RUK] Tlačové správy EN pr@uniba.sk Thu, 23 Mar 2023 09:27:00 +0100 https://uniba.sk/ AID OF COMENIUS UNIVERSITY IN BRATISLAVA AND ITS FACULTY OF LAW FOR UKRAINIAN STUDENTS AND ACADEMICS Comenius University in Bratislava for Ukrainian students: - has established a special e-mail address as a single contact point: ukrajina@uniba.sk - allocated 200 places at dormitories and waives accommodation fees from Ukrainian students -provides special scholarships (Ukrainian students of Faculty of Law CU can address the head of the Study Department, Mrs Helga Kovačičová) - will also provide the possibility of accommodation for family members (it is necessary to contact the single contact point and state the identification data of relatives of which the student wishes to accommodate) - provides services of psychological counselling   - will take into account student´s reduced participation in/absence from seminars Faculty of Law CU: - has established a special e-mail address as a single point of contact: info@flaw.uniba.sk - communicates or attempts to communicate with Ukrainian students of the faculty, including those who are physically present in Ukraine - if the faculty  manages to contact the Ukrainian students in Ukraine and they want to move to Slovakia, the faculty will arrange for them the transport from the state border by the faculty's company car and provide accommodation for them - the faculty will take into account the difficult conditions for the study of Ukrainian students (for example, when checking participation in teaching) - Ukrainian students will be waived the control phase of their studies this semester if they are unable to fulfil their study obligations properly; they are not advised to interrupt their studies in order not to lose their student status - aspects of support to refugees from Ukraine (e.g. legal aid in finding a job in Slovakia, etc.) will be incorporated into the Student Legal Counselling Centre, the capacity of which will be increased by additional students (additional enrolment will be enabled) - the faculty is ready to admit students of Ukrainian law faculties who are on the run from the war and would like to study law in Slovakia, the faculty will request the university to waive fees associated with the admission procedure for such applicants - Ukrainian students who will enrol in study programmes in English will be awarded a scholarship consisting of a waiver of tuition fees - 50 scholarships will be awarded in the study programme Law and 50 scholarships in the study programme Management and Law (subject to the approval of the Faculty of Management, which provides subjects in the part of Management) - the capacities of clinical subjects of the faculty will be increased, within which students can help Ukrainian refugees (for example, legal counselling regarding employment opportunities in Slovakia, etc.), or new Ukrainian students (student mentoring, assistance with introduction to law and legal Slovak); the faculty will specifically address current Ukrainian students - the faculty supports the friendship and assistance of Slovak students in relation to Ukrainian students and asks its students to take care of  Ukrainian students, e.g. as “study buddies”, and help them - the faculty will promote the amendment on the Education Support Fund so that it can also provide loans to Ukrainian students, the initiative will also be submitted directly to the director of the fund, Dr Kučmáš - the faculty will contact the partner Faculty of Law in Uzhhorod with an offer of assistance and will try to provide the required assistance within the possibilities of the faculty]]> [PraF] EN Titulka - úzke novinky Wed, 02 Mar 2022 15:50:00 +0100 https://uniba.sk/ The event takes place on 21 September 2023 (Thursday) in the afternoon.

Active Learning in Large Language Models Abstract:
In recent years the popularity of creating large language models has been incredibly rising. Most modern LLMs based on Transformers architecture offer great accuracy in many different text-based tasks but are often limited in some areas. For many low or mid-resource languages (such as Slovak), one of the biggest limitations is the amount of annotated data needed for fine-tuning such big model. Our work aims to highlight this problem with a BERT-line of models and suggest a promising method of reducing data for low-resource languages based on the recent developments in the area of Active learning thanks to the novel concept of Epistemic neural networks.]]> [FMFI] Prednášky a semináre [FMFI] Kalendár Damas.Gruska@fmph.uniba.sk Thu, 16 Mar 2023 11:00:00 +0100 https://uniba.sk/ As part of FMCU's cooperation with practice, we invite you to a guest lecture by IBM on the topic:...

Processing of light curves of satellites and space debris for the purpose of their identification

Abstract:
With the increase in space traffic in recent years, precise monitoring of space debris is necessary. Observations in form of light curves provide us with information about an object’s physical properties including shape, size, surface materials and rotation. Publicly available databases contain a huge amount of gathered light curves that can be used to train machine learning models. Pieces of space debris can fall down to the Earth in a process called reentry, therefore 3D reconstruction of this event can bring more understanding of the physical processes. ]]> [FMFI] Prednášky a semináre [FMFI] Kalendár Damas.Gruska@fmph.uniba.sk Wed, 15 Mar 2023 16:05:00 +0100
