The article discusses the problems of complex use of medications (polypragmasia) from the point of view of computational pharmaceutics and ensuring the completeness and accuracy of results caused by the diversity of sets of interactions used in machine learning.

The goal is to test the hypothesis that the use of deep learning technologies can allow the desired function to be extracted from a set of interaction results, which in turn can improve the accuracy of forecasting.

The research results in a solution based on the combined use of a convolutional neural network and an evolutionary algorithm. The architecture of the neural network and its operation are described. A mathematical model is presented, and data sets are formed for training and testing the neural network. Training is performed, and a comparative analysis of known algorithms is carried out in various forecasting modes.

The practical significance of the study is that the combined use of a convolutional neural network and a particle swarm algorithm will improve accuracy, sensitivity, selectivity, and reliability compared to known methods on similar datasets.
