Проанализировано пять брендов удобрений (NPK 16-16-8, NP(S) 12-40(10), NPK(S) 4-30-15(16), NPK(S) 0-20-20(5), МАФ (NP) 12-52). Сбор данных осуществляли с использованием визуального оптического и рентгенофлуоресцентного методов контроля. Описан способ выделения характеристических свойств промышленно производимых минеральных удобрений с построением матрицы «объекты-признаки». Приведены оценки качества определения физико-химических параметров удобрений (содержания N, P, К и общего содержания S, типа крупности запрессованных частиц и наличия предварительной сушки). Показана процедура нахождения оптимальных параметров каждого из исследованных алгоритмов классификации. Работа алгоритмов оценена с использованием Ф-меры (гармоническое среднее точности и полноты классификации). Обучение алгоритмов классификации и оценку качества их работы проводили по стратегии кросс-валидации на 10 наборах данных (фолдах) с отложенной выборкой (30 % от общего объема данных). Итоговое значение метрики качества рассчитывали как среднее по всем классам. Описано использование процедуры проекции на две главные компоненты для информативного представления исследуемых объектов на плоскости. В результате предложен комбинированный метод анализа для автоматизированного и информативного исследования производимой продукции.</p></abstract><trans-abstract xml:lang="en"><p>A comparison of different classification algorithms for dynamic description of the quality of industrially produced mineral fertilizers is presented. Five brands of fertilizers (NPK 16-16-8, NP(S) 12-40 (10), NPK(S) 4-30-15 (16), NPK(S) 0-20-20 (5), MAP (NP) 12-52) were analyzed using optical and X-ray fluorescence methods of control. A method of identifying the characteristic features of industrially produced mineral fertilizers using constructed “objects-characteristics” data array is described. Estimates of the quality of determination of physicochemical parameters of fertilizers (the content of N, P, К and total content of S, types of the particle size of the press-fitted granules and the pre-drying conditions) are given. The procedure of choosing optimal parameters for each considered classification algorithm is shown. The algorithms were estimated using the F-measure (harmonic mean of “precision” and “recall” of classifier). The training of the classification algorithms and assessment of the quality of their “work” were carried out according to the cross-validation strategy on 10 data sets (folds) with a delayed test (30% of the total data volume). The total value of the quality metric was calculated as the average for all classes. The use of the principal component analysis for informative representation of the studied objects on the plane is described. Finally, a combined method of analysis for automated and informative study of industrial products was proposed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>многомерная классификация</kwd><kwd>проекция на главные компоненты</kwd><kwd>качество работы алгоритмов</kwd><kwd>энергодисперсионный рентгенофлуоресцентный анализ</kwd><kwd>визуальный оптический контроль поверхности</kwd></kwd-group><kwd-group xml:lang="en"><kwd>multidimensional classification</kwd><kwd>principal component analysis</kwd><kwd>quality of algorithm</kwd><kwd>energy dispersive X-ray fluorescence analysis</kwd><kwd>visual optical control of the surface</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">Remes A., Saloheimo К., Jamsa-Jounela S.
