Представлено новое семейство нейросетевых моделей дискретных временных рядов, позволяющих аппроксимировать любой тип стохастической зависимости состояний временного ряда от его предыстории. Установлены условия эргодичности и отношение эквивалентности для этих моделей. Построены состоятельные статистические оценки параметров моделей и алгоритмы компьютерного анализа данных с использованием нейросетевых моделей: алгоритмы оценивания параметров, прогнозирования и распознавания образов.</p></abstract><trans-abstract xml:lang="en"><p>This article is devoted to constructing neural network-based models for discrete-valued time series and their use in computer data analysis. A new family of binomial time series based on neural networks is presented, which makes it possible to approximate the arbitrary-type stochastic dependence in time series. Ergodicity conditions and an equivalence relation for these models are determined. Consistent statistical estimators for model parameters and algorithms for computer data analysis (including forecasting and pattern recognition) are developed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>дискретный временной ряд</kwd><kwd>цепь Маркова</kwd><kwd>нейросетевая модель</kwd><kwd>оценки параметров</kwd><kwd>анализ данных</kwd></kwd-group><kwd-group xml:lang="en"><kwd>discrete-valued time series</kwd><kwd>Markov chain</kwd><kwd>neural networks-based model</kwd><kwd>estimators</kwd><kwd>data analysis</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Kellenher, J.
