Asteroids are the most numerous group of bodies in our Solar System. However, our observations are limited because of their size and distance. Occultations allow us to determine the shape and size of even the smaller ...

We study the extension of methods from classical survival analysis to competing risks. These methods can be used to analyse time-to-event data. Firstly, we establish notation, define fundamental concepts and present basic ...

This work discusses electromagnetic fields around Kerr black hole. We extend prior work by finding a new source term - a non-axial current loop. We analyze this solutions behaviour. We also discuss in detail the Meissner ...

The subject of the thesis is the estimation of the parameters of the Hull-White model. The formula for the time-dependent parameter θ is derived. The constant parameters α and σ are first calibrated on the prices of the ...

Stochastic optimization relies heavily on scenario generation, which has a large impact on the tractability of optimization methods and the quality of obtained solutions. Despite its importance, scenario generation for ...

Stochastic cooperative games - abstrakt (EN) Bc. David Ryz'ak May 2024 This thesis explores stochastic cooperative games, viewed here as cooperative games with a stochastic characteristic function, representing a generalization ...

Algebraic cryptanalysis is a standard set of techniques for analyzing and attacking practical symmetric cryptographic primitives. It involves representing the relationship between a pair of plaintext, ciphertext and the ...

We develop a method to train a document embedding model with an unlabeled dataset and low computational resources. Using teacher-student training, we distill SBERT's capacity to capture text structure and Paragraph Vector's ...

The aim of this thesis is to present some semiparametric methods used for estimating an unknown regression function. All approaches are based on a minimization of an ob- jective function, which is formulated as the sum of ...

Currently, Large Language Models are increasingly more successfully in open domain, being able to interact in a large number of tasks. But tasks and languages more sparsely represented in data the models where trained on ...

It can be shown that linear transformations of logarithm are the only utility functions whose optimal portfolios do not depend on numeraire. This thesis focuses on maximiza- tion of expected logarithmic utility of a general ...

We present a grammatical error correction system for correcting the Czech language. The system is based on the neural machine translation approach. We utilize the Trans- former architecture, which depends on a large amount ...

In deep learning, summarization models are traditionally trained using a maximum like- lihood objective with reference summaries. Another line of work explores self-supervised approaches that do not require and are not ...

In this thesis, the use of cross-validation methods in different areas of statistics is studied. Firstly, the application of leave-one-out cross- validation, CV(1), for bandwidth selection in kernel density estimation and ...
