Modeling of the Markiv random field for the purpose of its further optimization and application

Models of the Markov random field are investigated. The main improvements of the Markov random field model are investigated. If we consider Markov models of random fields with binary conditional distributions, which include stochastic evolution in time, which is based on the autoregression structure for a large-scale model, these models retain the flexibility of static Markov random field models to reproduce the representation of spatial dependence in a small-scale model. Bayesian estimation in this case is achieved through the use of a so-called algorithm that requires the generation of auxiliary random fields, but does not require the use of ideal samples. Markov random fields are a powerful tool in machine learning. It is often necessary to model such fields between dissimilar objects, which leads to the fact that the nodes in the graph belong to different types of data. To model inhomogeneous areas using graphical models, it is necessary to assign different types of distributions (binary, Gaussian, Poisson, exponent, exponential, etc.) to the model nodes. The concept of conditional random fields is considered in the article, their features, advantages and disadvantages are established. The application of binary data in Markov models of random fields is considered, which generates a class of models of binary Markov random fields. It is established that the discrete nature of Markov random fields allows a wider range of possible values of dependence, ie negative dependence. The model, loss function and distribution of the Markov random field function are investigated. Strengthening of Markov random fields is proposed. The pairwise exponential Markov random field is considered.
