    Hybrid random fields
    (2024) Zhydok, Fedir; Chornei, Ruslan
    Hybrid Random Fields is a class of graphical probabilistic models and it combines Bayesian Networks and Markov Random Fields models. Due to certain assumptions and properties of Hybrid Random Fields, it can simplify the calculation of joint distribution for a certain set of random variables and conditional probability densities for each of the random variables.

    Hybrid Random Fields
    (2024) Zhydok, Fedir; Chornei, Ruslan
    In this thesis, the capabilities of developed realization of Hybrid Random Fields is explored in terms of classification and regression tasks. The graphical model is compared to classical machine learning approaches in these tasks in terms of time and model quality. Furthermore, different structure learning approaches for Hybrid Random Fields are compared too in order to establish whether time-efficient K2 approach produces structures as well as hill-climbing algorithm with exhaustive search.
