Разработана система маршрутизации клиентов на основе их эмоционального состояния и возраста в системах обслуживания населения. Для разработки моделей предложен метод Squeeze-and-Excitation (SE), который отличается от существующих методов тем, что позволяет улучшить эффективность глубокой сверточной нейронной сети архитектуры, повышая информационный поток между слоями и усиливая важные признаки. SE метод основан на сжатии и возбуждении информации на каждом этапе свертки, что позволяет получить вектор оценок важности по каналам и использовать его для перевзвешивания каналов карты признаков. В работе показано, что SE метод позволил улучшить качество классификации и сократить время обучения модели. Метод. Для проведения маршрутизации клиентов в зависимости от их эмоционального состояния и возраста разработана математическая модель эмоциональной целевой маршрутизации на основе интерполяционного многочлена Ньютона. Интерполяционная функция в предложенной модели выполняет расчет времени ожидания клиентов в соответствии с их эмоциональным состоянием. Разработаны три модели бинарной классификации эмоций и возрастов: две модели для распознавания эмоционального состояния клиента и одна — для распознавания возраста. В первой и третьей моделях представлена глубокая сверточная нейронная сеть с использованием нового подхода SE на основе механизма внимания. Во второй модели применен метод опорных векторов. Основные результаты. Для тестирования модели после ее обучения применен метод evaluate, позволяющий оценить качество модели на новых данных, которые не были использованы при ее обучении. Это осуществлено для проверки, насколько точно модель может предсказывать значения целевой переменной на новых данных. Метод evaluate использует метрики оценки качества модели, такие как точность (accuracy), полнота (recall), F1-мера (F1-score). Выполнено сравнение эффективности методов на наборах данных FER-2013 и Adience, а также результатах, полученных в настоящей работе, с результатами, описанными в научных работах, опубликованных в базе данных Scopus. Согласно полученным экспериментальным данным, первая и вторая разработанные модели достигли точности валидации 72 % и 66 % соответственно, а их размеры составили 0,69 МБ и 369 МБ. В то же время модель распознавания возраста достигла точности 88 % при размере 1,68 МБ. Математическая модель эмоциональной целевой маршрутизации разработана для минимизирования конфликтов в системах обслуживания населения. Разработанная система может автоматически направлять клиентов по маршрутам в зависимости от их эмоционального состояния (наличия злости) и возраста к соответствующему оператору. Таким образом, клиенты старше 60 лет или с уровнем злости 60–80 % направляются к старшему оператору, который имеет опыт общения, с пожилыми клиентами или клиентами в возбужденном эмоциональном состоянии, а клиенты с уровнем злости 80–100 % направляются к психологу. Обсуждение. Результаты исследования могут быть применены в системах обслуживания населения для распознавания возраста и признаков злости клиентов. Разработанная система может быть применена, в различных областях, где есть контакт с большим количеством людей (например, банки, супермаркеты, системы контроля доступа в аэропортах, полицейские участки, метро и колл-центры).</p></abstract><trans-abstract xml:lang="en"><p>In this paper, we have developed a system for assigning customers to the routes based on their emotional state and age in Public Service Systems (PSSs). The Squeeze-and-Excitation (SE) method was used to develop the models, it improves the efficiency of the Deep Convolutional Neural Networks (DCNN) architecture by increasing the information flow between layers and enhancing important features. The method is based on compressing and exciting information at each convolution stage, which allows obtaining a vector of channel importance scores and using it to reweight the channels of the feature map. The study showed that this method allowed improving the quality of classification and reducing the model training time. The model of emotional target routing was developed based on the Newton interpolation polynomial to route customers based on their emotional state and age. The interpolation function in this model calculates the waiting time for customers according to their emotional state. Three models of binary classification of emotions and ages were developed, namely, two models for recognizing the emotional state of the customer, and one model for recognizing their age. The first and third models utilize DCNN from scratch using the new SE approach based on the attention mechanism. The second model uses the Support Vector Machine (SVM) method. The evaluate method was used to test the model after training, which allows evaluating the quality of the model on new data that was not used during training. This is done to check how accurately the model can predict the values of the target variable on new data. The evaluate method utilizes quality evaluation metrics such as accuracy, recall, and F1-score to assess the performance of the model. According to the experimental data obtained, the first and the second developed models achieved the validation accuracy of 72 % and 66 %, respectively, on the FER-2013 and Adience datasets. Their sizes were 0.69 MB and 369 MB, respectively. At the same time, the age recognition model achieved the accuracy of 88 % with the size of 1.68 MB. The mathematical model of emotional target routing (TERSS) was developed to minimize conflicts in public service systems. The developed system can automatically route customers based on their emotional state (presence of anger) and age to the appropriate operator. Thus, customers over 60 years old or with the anger level of 60–80 % are directed to a senior operator who knows how to communicate with elderly or emotionally excited customers, while customers with the anger level of 80–100 % are directed to a psychologist. This research can be applied in PSSs to detect the features of customers’ age and anger. Moreover, it can be applied in various areas where there is a contact with a large number of people, such as banks, supermarkets, airports access control systems, police stations, subways, and call centers.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>выражение лица</kwd><kwd>эмоция</kwd><kwd>возраст</kwd><kwd>классификация</kwd><kwd>DCNN</kwd><kwd>PSS</kwd></kwd-group><kwd-group xml:lang="en"><kwd>facial expression</kwd><kwd>emotion</kwd><kwd>age</kwd><kwd>classification</kwd><kwd>DCNN</kwd><kwd>PSS</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">Adigwe P., Okoro E.
