We compare two methods of classification: linear discriminant analysis and artificial feedforward neural networks. The comparison is carried out on the example of the task of classifying cyanobacteria in a series of self-fluorescence spectra of the individual cells. Methods of visualization and analysis of classification results, including new methods based on the entropy of classification results, have been demonstrated. The correlation between the results of linear discriminant analysis and classification of neural networks is determined. The key moments are shown, on the basis of which it is possible to reveal an incorrectly trained model of the neural network, and also a new method for analyzing the quality of the generalization is proposed. The methods of comparing the results of linear discriminant analysis and neural networks presented in the paper are applicable for comparing neural networks with other machine learning algorithms and statistical classifiers. The proposed method allows analyzing the le
