This paper the experimental research of dynamic characteristics self-similar scales of measurement financial time lines and quality check statistical, econometrics and intellectual methods of their analysis and forecasting is described. Research was carried out on 25 various financial time lines, including on lines of the prices of actions of the Russian and foreign companies, the prices for gold, oil, indexes of the MMVB, S&P, exchange rates, etc. The Analysis of these lines has confirmed presence of the common laws in change of structure of lines depending on scale.

Moments when a time series changes its behavior are called change points. Occurrence of change point implies that the state of the system is altered and its timely detection might help to prevent unwanted consequences. In this paper, we present two change-point detection approaches based on neural networks and online learning. These algorithms demonstrate linear ...

This study investigates combinatorial substitution schemes with various constraints on cycle sizes: lower bounds, upper bounds, and two-sided bounds. For the proposed schemes, we solve several enumerative combinatorics problems: determining the number of possible outcomes, constructing direct numbered enumerations, solving numbering problems (establishing bijective correspondences between indices and types of outcomes), deriving probability distributions over ...

Fault detection and diagnosis (FDD) is a critical challenge in industrial processes aimed at minimizing risks such as safety hazards, costly downtime, and suboptimal production. Traditional supervised FDD methods offer great performance while heavily relying on large volumes of labeled data, whereas unsupervised methods do not depend on labeled data, though are inferior in performance ...

Instability of the boundaries between past, present and future has been hotly debated in historical theory since at least K. Popper's “The Poverty of Historicism”. A new twist in this debate is linked to R. Koselleck's concepts of the "horizon of expectations" and F. Hartog's presentism, as well as to the debate about trauma and ...
