Ludwig von Mises’s Praxeology as the Foundation of Christian Economic Personalism
Studies in Logic, Grammar and Rhetoric, 2019 What can an economist and agnostic tell a theologian about man? In contrast to mainstream economics, which today dominate all universities in the world, Ludwig von Mises (+1973) is interested in real man in action, not a fictitious homo oeconomicus.

Recommendation Algorithm Using SVD and Weight Point Rank (SVD-WPR)
Big Data and Cognitive Computing, 2022 One of the most prevalent recommendation systems is ranking-oriented collaborative filtering which employs ranking aggregation. The collaborative filtering study recently applied the ranking aggregation that considers the weight point of items to achieve a more accurate recommended ranking.

Principal component analysis and its generalizations for any type of sequence (PCA-Seq)
Вавиловский журнал генетики и селекции, 2020 In the 1940s, Karhunen and Loève proposed a method for processing a one-dimensional numeric time series by converting it into multidimensional by shifts. In fact, a one-dimensional number series was decomposed into several orthogonal time series.
