Точная, быстрая и неинвазивная диагностика этих заболеваний имеет важное значение в промышленном производстве земляники. В настоящей статье исследуются возможности применения методов машинного обучения и гиперспектральной визуализации для обнаружения и дифференциации на листьях земляники симптомов, вызванных патогенными грибами Ramularia tulasnei Sacc., Marssonina potentillae Desm. и Dendrophoma obscurans Anders. Спектр отражения листьев регистрировали гиперспектральной камерой Photonfocus MV1-D2048x1088- HS05-96-G2-10 в лабораторных условиях методом линейного сканирования. Для дифференциации здоровых и пораженных областей листьев изучено пять методов машинного обучения: метод опорных векторов (SVM), метод К-ближайших соседей (KNN), линейный дискриминантный анализ (LDA), дискриминантный анализ частичных наименьших квадратов (PLS-DA) и случайный лес (RF). С целью уменьшения высокой размерности извлеченных спектральных данных и увеличения скорости их обработки было отобрано несколько подмножеств оптимальных длин волн, несущих наиболее важную спектральную информацию. Рассмотрены следующие методы сокращения размерности: метод анализа ROC-кривых, метод анализа производных, метод PLS-DA, метод ReliefF. Кроме того, 16 вегетационных индексов задействовано в качестве информативных признаков. Наибольшую точность классификации, 89.9 %, показал метод опорных векторов на полном спектре значений. При использовании вегетационных индексов и наборов оптимальных длин волн общая точность классификации всех методов снизилась незначительно по сравнению с классификацией на полном спектре значений. Результаты исследования подтверждают перспективность применения методов гиперспектральной визуализации в сочетании с методами машинного обучения для дифференциации грибных болезней земляники садовой.</p></abstract><trans-abstract xml:lang="en"><p>Leaf spot, leaf scorch and phomopsis leaf blight are the most common fungal diseases of strawberry in Western Siberia, which significantly reduce its yield and quality. Accurate, fast and non-invasive diagnosis of these diseases is important for strawberry production. This article explores the ability of hyperspectral imaging to detect and differentiate symptoms caused to strawberry leaves by pathogenic fungi Ramularia tulasnei Sacc., Marssonina potentillae Desm. and Dendrophoma obscurans Anders. The reflection spectrum of leaves was acquired with a Photonfocus MV1-D2048x1088-HS05-96-G2-10 hyperspectral camera under laboratory conditions using the line scanning method. Five machine learning methods were considered to differentiate between healthy and diseased leaf areas: Support Vector Machine (SVM), K-Nearest Neighbors (KNN), Linear Discriminant Analysis (LDA), Partial Least Squares Discriminant Analysis (PLS-DA), and Random Forest (RF). In order to reduce the high dimensionality of the extracted spectral data and to increase the speed of their processing, several subsets of optimal wavelengths were selected. The following dimensionality reduction methods were explored: ROC curve analysis method, derivative analysis method, PLS-DA method, and ReliefF method. In addition, 16 vegetation indices were used as features. The support vector machine method demonstrated the highest classification accuracy of 89.9 % on the full range spectral data. When using vegetation indices and optimal wavelengths, the overall classification accuracy of all methods decreased slightly compared to the classification on the full range spectral data. The results of the study confirm the potential of using hyperspectral imaging methods in combination with machine learning for differentiating fungal diseases of strawberries.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>гиперспектральные изображения</kwd><kwd>грибные болезни земляники</kwd><kwd>методы машинного обучения</kwd><kwd>сокращение размерности</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hyperspectral imaging</kwd><kwd>fungal diseases of strawberries</kwd><kwd>machine learning methods</kwd><kwd>dimensionality reduction</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">Benos L., Tagarakis A., Dolias G., Berruto R., Kateris D., Bochtis D.
