A New Method Towards Speech Files Local Features Investigation [article]

Rustam Latypov, Evgeni Stolov
2020 arXiv   pre-print
There are a few reasons for the recent increased interest in the study of local features of speech files. It is stated that many essential features of the speaker language used can appear in the form of the speech signal. The traditional instruments - short Fourier transform, wavelet transform, Hadamard transforms, autocorrelation, and the like can detect not all particular properties of the language. In this paper, we suggest a new approach to the exploration of such properties. The source

Examination of the distribution of the produced vectors provides a new method for a description of speech files local characteristics. Finally, the developed technique is applied to the problem of the automatic distinguishing of two known languages used in speech files. For this purpose, a simple neural net is consumed.

A new watermarking method to protect blockchain records comprising handwritten files [article]

Rustam Latypov, Evgeni Stolov
2019 arXiv   pre-print
A new type of watermarks for handwritten black-white documents is suggested. Insertion of the watermark in a document minimizes distortion of the latter. The method is intended for validation of handwritten records placed in blockchain database.

2019 arXiv   pre-print
In this paper, we propose a novel archival system called ARCHAIN, developed for the State archive-keeping committee of the Republic of Tatarstan (Russia). The blockchain is the primary part of the system, which stores transactions (facts of transfer of documents to the archive) in a protected form.

Speaker Diarization Based on Speech Signal Approximation by Step Function

Rustam Latypov, Evgeni Stolov
2021 Zenodo  
In this paper, we describe a new method for speaker clustering in an audio file. The main idea is to replace the speech signal with a step function having a limited number of levels. The research goal is to determine the signal characteristics obtained from the analysis of the step function produced. The step function is created by setting multiple levels that divide the signal range into non-overlapping strips. All the source signal values, which are inside a stip, are changed for the strips

We employ the obtained results to solve the problem of speaker diarization. The developed diarization algorithm requires little computer resources. The experiments show the suitability of the developed results to the conditions of the online diarization process.

Coloring Trees in Massively Parallel Computation [article]

Rustam Latypov, Jara Uitto
2021 arXiv   pre-print
We present O(log^2 log n) time 3-coloring, maximal independent set and maximal matching algorithms for trees in the Massively Parallel Computation (MPC) model. Our algorithms are deterministic, apply to arbitrary-degree trees and work in the low-space MPC model, where local memory is O(n^δ) for δ∈ (0,1) and global memory is O(m). Our main result is the 3-coloring algorithm, which contrasts the randomized, state-of-the-art 4-coloring algorithm of Ghaffari, Grunau and Jin [DISC'20]. The maximal

The key ingredient of our 3-coloring algorithm is an O(log^2 log n) time adaptation of the rake-and-compress tree decomposition used by Chang and Pettie [FOCS'17], and established by Miller and Reif. When restricting our attention to trees of constant degree, we bring the runtime down to O(loglog n).

Ternary jitter-based true random number generator

Rustam Latypov, Evgeni Stolov
2017 Journal of Physics, Conference Series  
In this paper a novel family of generators producing true uniform random numbers in ternary logic is presented. The generator consists of a number of identical ternary logic combinational units connected into a ring. All the units are provided to have a random delay time, and this time is supposed to be distributed in accordance with an exponential distribution. All delays are supposed to be independent events. The theory of the generator is based on Erlang equations. The generator can be used

For these purposes we propose module for preliminary homework checking, statistical module and feedback module that can be extended to the separate rating system. The variety of interfaces is supported by three components: desktop application, mobile application and web-based application. Although we concentrate on desktop and mobile forms as according to the statistical data they are more usable. The difference of European, American and Russian systems of education predetermine some aspects in the design approach. It allows to use the strongest advantages of every model in the solution and to share the multinational experience. The paper describes in details the highlighted moments.

A New Method for Slant Calculation in Off-Line Handwriting Analysis

Rustam Latypov, Evgeni Stolov
2018 2018 41st International Conference on Telecommunications and Signal Processing (TSP)  
In this paper, we propose a new method for estimating the slant of word in handwritten text. The method allows a researcher to analyze snippets of a picture containing a few words in different lines. The main goal of the research is to present a tool to observe small changes of slant in the text during work. Student check sheets were used as a database for the research. Some changes in slant depending on speed of writing are discovered.
