Использованы четыре алгоритма выбора спектральных переменных: CARS, RF, GA и VIP, для определения характерных полос, устойчивых к помехам воды, при комбинировании с методом частичных наименьших квадратов (PLS) для построения модели надежного количественного определения Hb. Применимость и достоверность модели подтверждены с использованием трех прогнозных наборов P1, P2, P3 с различным водным фоном (метод составления и состав оставались прежними, последовательно увеличивалось лишь содержание воды). Показано, что с помощью алгоритмов RF, GA и VIP можно исключать характерные длины волн Hb с низкой чувствительностью к изменениям количества воды и успешно корректировать влияние воды, однако из-за большого количества характеристических переменных исключается и большое количество избыточных переменных, в том числе переменных, относящихся к помехам воды, что в конечном итоге делает модель несовершенной. Алгоритм CARS показывает лучшие результаты, а RMSEP трех прогнозных наборов составляет 0.016, 0.017 и 0.038, что ближе к RMSECV калибровочного набора. Следовательно, NIRS в сочетании с выбором переменных может уменьшить влияние воды на надежность модели и повысить точность прогнозирования модели методом выбора эффективных интервалов волновых чисел, а CARS может быть одним из идеальных алгоритмов для решения таких задач.</p></abstract><trans-abstract xml:lang="en"><p>The background differences in water content of different samples have a very strong influence on the robustness of near-infrared spectroscopy (NIRS). For this reason, this study simulated typical biological water matrix samples with formulated hemoglobin (Hb), glucose (Glc), and distilled water, and attempted to use four different intelligent spectral variable selection algorithms (Competitive Adaptive Re-weighted Sampling (CARS), Randomized Frog Hopping Algorithm (RF), Genetic Algorithm (GA), and Variable Projection Importance Algorithm (VIP)) to perform the Hb water interference-resistant feature band preferences, while combining partial least squares (PLS) in parallel to build a robust quantitative model of Hb. In addition, the applicability and validity of the model were validated using three prediction sets P1, P2, P3 with different water backgrounds (the formulation method and composition were kept the same, and only the water content increased sequentially). The results showed that RF, GA, and VIP could effectively screen out the characteristic wavelengths of Hb with low sensitivity to water changes and successfully correct the water effect, but due to the large number of characteristic variables they screened out and the existence of a large number of redundant and water interference variables, this ultimately made the model’s robustness less than ideal. The CARS algorithm performed the best, and the RMSEP of the three prediction sets were 0.016, 0.017, and 0.038, which is closer to the RMSECV of the calibration set. Therefore, NIRS combined with the variable selection can reduce the effect of water on model robustness and improve the prediction accuracy of the model by the method of selecting effective wave number intervals, and CARS may be one of the ideal algorithms to solve such problems.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>спектроскопия ближнего инфракрасного диапазона</kwd><kwd>гемоглобин</kwd><kwd>алгоритм выбора переменных</kwd><kwd>водоустойчивая модель</kwd></kwd-group><kwd-group xml:lang="en"><kwd>near-infrared spectroscopy</kwd><kwd>hemoglobin</kwd><kwd>variable selection algorithm</kwd><kwd>water robust model</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The authors gratefully acknowledge the support of the National Natural Science Foundation of China (No. 42075135) and the President's Fund Project of Hefei Institute of Materials Science, CAS (No. YYJJ2022QN09).</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">D.
