A combined approach to part-of-speech homonymy resolution

The Russian language has an inflective structure and does not have a strict word order, which generates processing problems such as part-of-speech homonymy. The paper addresses this issue. The existing approaches to resolving the morphological homonymy problem can be divided into the following groups: rule-based approaches, statistical approaches, machine learning...

Forecasting the transport network development based on statistical analysis in the MIX-PROSTOR system

We are considering the problem of the analysis of transport network development in the MIX-PROSTOR system. The “what-if” analysis allows for setting some variations of the network parameters and calculating their consequences. In a sense, we are trying to solve the inverse problem: what ranges of network parameter modification leads...

Analysis of noise stability of strip-transformation

In the paper, variations of the strip-method are investigated. Namely, we considered variants based on using different matrices: Hadamard, Haar, Frobenius, S-matrices, etc. These variants of the strip-method were implemented. The main purpose is to study the quality of restoration of one-dimensional signals (images are not considered) for various matrices...

Graph quotients: a topological approach to graphs

This paper develops general concepts useful for extracting knowledge embedded in large graphs or datasets that have pair-wise relationships, such as relations of cause-effect type. Almost no underlying assumptions are made, other than that the data can be presented in terms of pair-wise relationships between objects/events. This assumption is used...
