Экспериментальные УФ-спектры имидаклоприда различных концентраций в яблочном соке предварительно обработаны сглаживанием Савицкого-Голея. Затем переменные признаков выбраны с помощью алгоритмов итеративного сжатия пространства переменных (VISSA), алгоритмов итеративного сохранения информативных переменных (IRIV) и алгоритмов случайной лягушки (RF). Для обнаружения имидаклоприда в яблочном соке созданы модели прогнозирования опорной векторной регрессии с поддержкой роя частиц (PSO-SVR), основанные на переменных признаков и переменных полного спектра. Получено, что модель VISSA-PSO-SVR имеет оптимальную прогностическую эффективность, коэффициент детерминации набора прогнозов Rp2 = 0.99933, среднеквадратическая ошибка набора прогнозов RMSEP = 0.0894 мг/л.</p></abstract><trans-abstract xml:lang="en"><p>   The widespread use of pesticides poses many potential risks to food safety and human health. Thus, rapid and accurate detection methods for pesticide residues need to be established. In this study, ultraviolet (UV) spectroscopy coupled with support vector regression and variable selection methods was used to quantitatively detect the content of imidacloprid in apple juice. First, the UV spectra of different imidacloprid concentrations in apple juice were collected, and the acquired spectra were preprocessed by Savitzky-Golay smoothing. Then, the feature variables were selected by the variable iterative space shrinkage approach (VISSA), iteratively retains informative variables (IRIV), and random frog (RF) algorithms. Finally, particle swarm optimization support vector regression (PSO-SVR) prediction models based on the feature variables and the full-spectrum variables were established to detect imidacloprid in apple juice. The results showed that the VISSA-PSO-SVR model had the optimal predictive performance, the determination coefficient of the prediction set (Rp2) was 0.99933, and the root mean square error of the prediction set (RMSEP) was 0.0894 mg/L. The results from this study indicated that the combination of UV spectroscopy and the VISSA-PSO-SVR model could be used for the quantitative detection of imidacloprid in apple juice.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ультрафиолетовая спектроскопия</kwd><kwd>регрессия опорных векторов</kwd><kwd>методы отбора переменных</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ultraviolet spectroscopy</kwd><kwd>support vector regression</kwd><kwd>variable selection methods</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Эта работа была частично поддержана Китайским научным фондом постдокторантуры (№ 2022M711620)</funding-statement><funding-statement xml:lang="en">This work was partially supported by China Postdoctoral Science Foundation (No. 2022M711620)</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">T.
