. The current trends in the field of credit scoring in the banking sector are considered. The role of online applications, regulation of creditworthiness assessment, the use of neural network models and recurrent neural networks in scoring, as well as the importance of transaction data for optimizing the credit process are shown. Methods for analyzing transaction data to evaluate potential borrowers are proposed. Legacy risks and data privacy issues are also considered in the context of the use of transaction information

The expediency of integral representation of the activity of the person making decisions in managing the portfolio of securities, the socioeconomic organization, in the framework of which he fulfills his functional duties, as well as information support, decisions made by him, in the form of a sociokiberphysical system is shown. It was established that the latter has a negative property - the psychological unpredictability of the decision maker, due to the influence of a difficult situation on the securities market, which can lead to the destruction of the portfolio, and, as a result, significant financial losses. In difficult conditions, in order to reduce the negative effect of this property, it was proposed to improve the information support of the decision maker in terms of taking into account the past positive experience of the actions of experts in such conditions. It has been shown that the implementation of such an approach requires the inclusion in the overall portfolio management process of solving intellectual private problems. A five-stage portfolio management model with integrated intelligent private tasks is offered. A follower of the solution of one of the important among them - the task of preserving and maintaining expert strategies for asset manipulation, based on the use of a neural network, is presented
