The subject of research in the article is the software implementation of a neural image classifier. The work examines emotions as a special type of mental processes that express a person’s experience of his attitude to the surrounding world and himself. They can be expressed in different ways: facial expressions, posture, motor reactions, voice. However, the human face has the greatest expressiveness. Technologies for recognizing companies to improve customer service use human emotions make decisions about interviewing candidates and optimize the emotional impact of advertising. Therefore, the purpose of the work is to find and optimize the most satisfactory in terms of accuracy algorithm for classifying human emotions based on facial images. The following tasks are solved: review and analysis of the current state of the problem of "recognition of emotions"; consideration of classification methods; choosing the best method for the given task; development of a software implementation for the classification of emotions; conducting an analysis of the work of the classifier, formulating conclusions about the work performed, based on the received data. An image classification method based on a densely connected convolutional neural network is also used. Results: the results of this work showed that the method of image classification, based on a densely connected convolutional neural network, is well suited for solving the problems of emotion recognition, because it has a fairly high accuracy. The quality of the classifier was evaluated according to the following metrics: accuracy; confusion matrix; precision, recall, f1-score; ROC curve and AUC values. The accuracy value is relatively high – 63%, provided that the data set has unbalanced classes. AUC is also high at 89%. Conclusions. It can be concluded that the obtained model with weights has high indicators of recognition of human emotions, and can be successfully used for its purpose in the future.
