Application of neural networks for recognition of conformational changes in protein structure by X-ray diffractograms of its single molecules on the example of bacteriorhodopsin photocycle

Free electron lasers are becoming increasingly powerful and affordable installations for determining the structure of proteins. Conformational rearrangements are characteristic of the vast majority of proteins, but the transience of transformations often does not allow obtaining crystals of sufficient size. The solution could be to obtain X-ray diffraction patterns from single molecules, but in this case it is not possible to determine their orientation, which makes it impossible to restore the structure by modern methods. The paper considers the applicability of a number of neural network architectures to the recognition of the conformational state of a protein based on diffraction data on single bacteriorhodopsin molecules.

Keywords: X-ray diffraction, neural networks, conformational states of protein, bacteriorhodopsin

Lugachev M.I., Skripkin K.G., Gimranov R.D. Artificial Intelligence Services in Modern Economy

In the contemporary economy, we see evidence of the “productivity paradox” — investments in new information technology do not increase labor productivity on the national economy level. We suppose that centralized online platforms dominating the modern digital economy are the key drivers of this paradox. Artificial Intelligence (AI) development strengthens their dominance due to the concentration of data necessary for AI algorithms learning. At the same time, the business models of online platforms were developed at the turn of the 1990s – 2000s and may not be optimal in the presence of other metaphors, primarily peer-to-peer networks. To limit the dominance of centralized online platforms, the government needs to change its policy towards them, including leading domestic operators. To reduce platform operators’ monopoly power, we propose dividing operators into companies that support collecting and processing data on platforms and business operators that use this data to provide end-user services.

Keywords: productivity paradox, centralized online platform, business model, peer-to-peer platform

Shokurov A. V. Embedded vision: from objective to hardware implementation

It’s one thing to solve a problem mathematically and develop an appropriate method, but it’s quite another to port it to hardware components. Even seemingly simple tasks require careful thought software architecture hardware implementation. It is necessary to understand the device of RAM and internal memory, including hardware mechanisms for direct copying of data from various subsystems, and the functioning of individual subsystems (controllers) of a large system (system on a chip), as well as their interaction. It is necessary to understand the structure of RAM and internal memory, including hardware mechanisms of direct data copying from various subsystems, and functioning of individual subsystems (controllers) of a large system (system on a chip), as well as their interaction. In particular, take into account that calculations can be performed not only on the processor, but, for example, on some controller. So, there are tensor calculations, and there are even more specialized digital image processing based. Even the effective output of graphic information requires attention from the developer, otherwise artifacts (data distortion) may occur during their visualization. For the performance of methods, not only is the mathematical factor important, but also the hardware implementation support of seperate algorithm elements. The latter is reflected in modern computing systems and embedded processors architectures.

Keywords: hardware implementation, processor, random access memory, controller.

Gasanov E.E., Suyunbekova M.B. On a new algorithm for reaching consensus for stablecoins

Cryptocurrencies, the price of which is tied to physical assets, are called stablecoins. This paper shows that for stablecoins, the use of a Proof-Of-Work consensus-building algorithm is impractical, because someone will have to pay for the hard work done to reach a consensus, and the amount of money in the system will decrease. This paper proposes a new consensus-building algorithm based on the lottery principle that can be used for stablecoins and for digital currencies of central banks.

Keywords: Cryptocurrencies, digital currencies of central banks, consensus building algorithms.

Fast multiplication algorithms for both large numbers and large square matrices are considered here. When multiplying numbers, a group algebra is introduced, and the Fourier transform is expressed as a representation of the elements of the group algebra in another basis associated with characters. Next, bigroup algebra is introduced as an extension of group algebra operators using characters acting as diagonal matrices in the standard basis of group algebra. The analogue of multiplication of large numbers by the Fourier transform extends to group algebra, i.e. to the algebra of matrices.

Aidagulov R.R. Bigroup algebras and Potter’s theorem

Cluster analysis has a very wide range of applications; its methods are used in medicine, chemistry, archeology, marketing, geology and other disciplines. Clustering consists of grouping similar objects together, and this task is one of the fundamental tasks in the field of data mining. Usually, clustering is understood as a partition of a given set of points of a certain metric space into subsets in such a way that close points fall into one group, and distant points fall into different ones. In this paper, we offer a local averaging method for calculating the distribution density of data as points in a metric space. Choosing further sections of the set of points at a certain level of density, we get a partition into clusters. The proposed method offers a stable partitioning into clusters and is free from a number of disadvantages inherent in known clustering methods.

Keywords: cluster, algorithm, density, averaging method.

Gorny B.E., Zudin A.V., Ryjov A.P. Measurement of alcohol well-being in regions based on statistical information

To reduce the risks associated with alcohol abuse, it is extremely important to assess alcohol consumption levels. At the same time, it is not enough to know indicators that assess only the volume of retail sales, which does not take into account unrecorded alcohol consumption. The development of an integral indicator of the index, based on available statistical data, will make it possible to level the risks of expert assessment and increase the efficiency of spending budget funds in the field of healthcare. The report provides a description of the available expert and factual information, the structure of the index, an approach to its assessment by means of the theory of fuzzy sets is proposed. The features of the implementation of the index calculation in the Matlab environment are considered, examples are given. The related direct and inverse problems are formulated and discussed, the solution of which will optimize the efficiency of the healthcare system in this parameter at the regional and federal levels. The alcohol well-being index is one of the important parameters of the health care system, on the one hand, and a typical index of socio-economic processes, on the other, therefore, the approaches described in the report can be applied to construct a wide set of such indices.

Keywords: preventive medicine, alcohol well-being, process evaluation and monitoring.

Beskova I.A. Semantics of Belief Contexts in the Natural Language Analysis

The idea of the presentation addresses to possibility of logical- semantic tools applying in the natural language analysis. Epistemic contexts have been chosen as the most productive for such analysis, since they impose high requirements on systems trying to represent their dynamics. In particular, the truth relation between the sub- operative expression and the complex sentence containing it is not obvious: though the sub-operative expression is false, the complex expression may be true, and vice versa. Another non-obvious point: it is impossible to perform substitution in such contexts based on the values’ identity; a coincidence in meaning (synonymy) is required. In this regard, a kind of intuitively transparent scheme of belief contexts semantics’ understanding based on the concept of ideal worlds is proposed.

Keywords: epistemic contexts, semantics, natural language, denotation, meaning.

Bogomolova A.D. Cluster network approach to natural language analysis and its applications

The method combines the capabilities of machine learning and human cognitive abilities which is an efficient way to analyze large amounts of data. The method is suitable for a variety of purposes and in this article there are some examples of its applications.

Keywords: Cluster approach, natural language analysis, patent analysis, tokenization, network

Angelina Bolshina The Creation of Pseudo-Annotated Data for Word Sense Disambiguation using Ensembles of Models

Nowadays, supervised word sense disambiguation (WSD) algorithms attain the best results on the main benchmarks. However, large sense- tagged training sets are required for their training. This requirement hinders the development of the word sense disambiguation systems for many low-resource languages, including Russian. To address the issue of the knowledge acquisition bottleneck in Russian, in this work we investigate the method for automatic text labelling that is based on the ensemble of weakly supervised WSD models. Our experiments demonstrated that the models retrained on the new pseudo-annotated data outperform the initial models.

Keywords: Word sense disambiguation; Russian dataset; ELMo; BERT.

Kalabikhina I.E., Loukachevitch N.V., Banin E.P., Alibaeva K.V. Automated Analysis of Family Values of VKontakte Users

The paper examines opinions of VKontakte network users about having births. A dataset annotated with opinions on three classes of positions towards six childbirth-related topics. Experiments on automatic classification of opinions have been carried out. The best results were obtained using neural network model BERT in the formulation of NLI (Natural language Inference). It was revealed that the phenomenon of conscious childlessness is actively represented in the network, while having many children remains a poorly widespread model of behavior. Within the framework of a pro-natalist policy, it is important to support a positive public opinion about parenting, to develop family-life balance for parents.

Keywords: stance detection, classification, BERT, VKontakte, reproductive values, pro-natalist policy.

Katser I.D., Kozitsin V.O. Machine Learning Based Oil Pipeline Diagnostics

The magnetic flux leakage (MFL) method is the most common approach for non-destructive testing of oil and gas pipelines. As a result of MFL detection, magnetograms are obtained, often analyzed by semi-automated methods, which leads to a decrease in accuracy and an increase in analysis time. The paper proposes a new CNN architecture for automatic image classification based on magnetograms for oil pipeline diagnostics. As a result of testing the developed algorithms on a deferred sample, the high accuracy and efficiency of the developed solution were proved.

Kozitsin V.O., Katser I.D. An open-source framework for anomaly detection and forecasting of technical systems

Modern technical systems such as power plants are equipped with diagnostic systems. But these systems are imperfect, and accidents still happen. Accidents can lead not only to economic losses but also to socially frightening consequences, such as human-made catastrophes. Another one, that seems to be a typical, problem for Nuclear Power Plant is the excessive duplication of safety systems, which increases the cost of the NPP itself. The solution could be an advanced diagnostic system. Diagnostics as science can be divided into the main three parts: the first one is the monitoring of technical conditions; the second one is finding the root cause of anomalies; the third one is the forecasting of the future state of a technical system. The developed framework can be used to solve all these diagnostics tasks.

Kiselev M.V. Spiking neural network unsupervised learning algorithm SCoBUL and its application to extracting informative features from DVS camera signal

A principally new type of video cameras, the so-called DVS (dynamic vision sensors), became commercially available recently. They are capable of enhancing dramatically speed and energy consumption parameters of video signal processing procedures because they send asynchronous stream of spikes indicating brightness change of individual pixels instead of scanned raster data of the whole camera view field. However, this new kind of output signal requires novel algorithms for its processing. Such an algorithm called SCoBUL (spike correlation based unsupervised learning) is described in the present work. SCoBUL uses a one-layer spiking neural network with lateral inhibition for extracting informative features from spike trains in unsupervised learning regime. SCoBUL‘s most important feature is a generalization of STDP (spike timing dependent plasticity) rule optimized especially for this task.

Lazutkin A.A., Shuvaev S.A. DOGHOUSE: a new assay to probe spatiotemporal dynamics of brain-wide activity

To analyze the data generated with whole-brain staining and imaging approaches, several assays have been proposed registering brain samples to atlases and detecting stained cells in individual brain regions. However, the algorithms for quantifying labeled cells in the brain and grounding these counts to the brain’s functional anatomy are still in the early stages of development. To bridge this gap, we introduce DOGHOUSE, an end-to-end assay for probing spatiotemporal dynamics of brain-wide activity. The assay consists of two components. CORGI, a software package for registering whole- brain sample data in space and time, overcomes the differences between dissimilar perinatal brains. DALMATIAN, a software package for cell detection in whole-brain sample data, separates densely packed dividing cells. The staining protocol has been validated for the staining specificity whilst the software packages have shown competitive performance meeting or exceeding the state-of-the-art on diverse datasets. Our assay automates a variety of tasks including group comparison and monitoring brain development dynamics. All methods are available for download via open access.

We investigated the collective activity of the CA1 place field neurons of the mouse hippocampus during free exploration task. Using methods of nonlinear dimensionality reduction, we showed that the activity of a population of several hundred cells can be reduced to two collective variables that determine the position of the animal on the explored environment. Our results support the distributed coding hypothesis and can be used to analyze the collective activity of neurons in other brain regions.

Keywords: place neurons, dimension reduction, distributed coding.

Calcium activity of the retrosplenial cortex neurons during object and place recognition in mice Rogozhnikova O.S., Ivashkina O.I., Toropova K.A., Solotenkov M.A., Fedotov I.V., Zheltikov A.M., Anokhin K.V.

The retrosplenial cortex (RSC) plays a key role in the processes of spatial navigation and coding of spatial information. However, the participation of the RSC in encoding information about objects has been studied little. In this work, we used fiber-optic photometry to record RSC calcium activity in novel object and novel place recognition tasks. We have shown that at the moment of animal contact with the object, there is a decrease in the calcium activity of the RSC, regardless of the behavioral task. At the same time, the performance of another form of exploration behavior — rearing, was not accompanied by a similar decrease in the activity of the RSC. Thus, we have shown a specific change in the activity of RSC during the object exploration in mice.

Keywords: retrosplenial cortex, object recognition, calcium imaging, exploratory behavior.

Teplyuk A.V. Neuromorphic machine vision systems

Neuromorphic computer vision systems, also called event cameras, are sensors whose basic principle of operation was borrowed from the physiological principle of how human vision works. They differ from traditional cameras in that instead of taking pictures at fixed intervals, they asynchronously detects changes in the brightness of each point in the observed space. At the output, these sensors generate a stream of data packets, where each packet corresponds to a brightness change event, and the packet itself contains information about time the event occurs, pixel coordinates and the nature of the brightness change (increase or decrease). The article describes principles of event cameras operations. Provides an overview of main advantages of event cameras, as well as the most promising areas for using this technology in various fields of human activity.

Keywords: Event cameras, machine vision, neuromorphic systems, computer vision, asynchronous sensors, high dynamic range, robots.

B. Thalheim Artificial Intelligence Enhanced By Modelling

One of the biggest hypes in current research is Artificial Intelligence. Similar to the AI 1.0, 2.0, and 3.0 hypes, the claim is that AI will help to solve all problems everywhere and anytime, will replace almost all human activities by greater machinery, will be far more intelligent than humans, will be far more reliable than humans, and will be the basis for greater wealth. We briefly investigate whether it is possible and figure out that these and other promises are not realistic. A silver bullet is, however, modelling since it is more concerned with human intelligence.

Keywords: artificial intelligence, human intelligence, modelling, AI models.

Bryzgalina E.V. Philosophical analysis of restrictions of using artificial intelligence systems in education

The report demonstrates that the development of AI systems is associated with personalization and individualization of educational process through the formation of individual educational programs, an individual schedule of the educational process, taking into account individual experience, style of thinking, level of knowledge, for maximum psychological comfort of the child. Proponents of the use of AI in education highlight a number of possible advantages of AI technologies for a child: novelty, possible increase in involvement and motivation; the ability to set individual tasks, depending on the characteristics, which helps child to feel special. Education should address the dilemma of individual autonomy and public good, as AI raises the tension between privacy, respect for human dignity and autonomy, and understanding education as a public good. A very acute problem is the confidentiality of information, the definition of modes and levels of accessibility to the information with which the AI works, and the recommendations that it gives. Dattification in education runs the risk of becoming a factor of stigma and discrimination. AI systems can serve to enhance social normalization, that is, the result of using AI can be exactly the opposite than personification. The problem of responsibility in the application of AI and the problem of creating "trustworthy AI"have not been solved for education. The ethics of the child’s interaction with artificial intelligence needs to be developed, the psychological effects of the child’s interaction with the AI system are not clear.

Keywords: philosophy of education, artificial intelligence, essence of education, ethics of artificial intelligence.

Vinokurov F.N., Panov K.A. The Great Equalizer. Can a voice assistant moderate group interaction?

In recent years a new field of study has appeared in social psychology. It concerns voice assistants that contribute to major changes in our society during its relatively brief existence. They are being increasingly used in situations that require multi-user interaction: in families, classrooms and, more importantly, in task- oriented workgroups. This study analyzes a process of group interaction moderation by a voice assistant. The algorithmic repetition of the voice assistant’s lines, noticeable to the group members, reduces involvement in the interaction process. Due to technical limitations the members of the group organize collective activities to build interaction with the voice assistant. This allows to increase the perceived cohesion in the early stages of group development. This study analyzes a process of group interaction moderation by a voice assistant. The algorithmic repetition of the voice assistant skill, noticeable to the group members, reduces involvement in the interaction process. However, due to technical limitations members of the group organize their joint activities to better interact with the voice assistant. This allows to increase the perceived cohesion in the early stages of group development.

Keywords: Human–computer interaction, Voice assistant, Group interaction.

Keywords: neural networks, complex systems modeling, computational neuroscience.

Ryjov A.P. Problems of Hybrid Intelligence Systems Development

The report describes the concept of human-computer intelligent systems (hybrid intelligence systems), the main problems of their development, provides examples of such systems for organizations at the international, federal, and corporate levels. The focus is on the analytical capabilities of such systems. Formulations of direct and inverse problems are given. It is shown that, in contrast to standard OLAP analytics (analysis of the past) and from data mining analytics (forecasting the future), such systems allow constructing the future. In particular, understand what and how should be changed in the analyzed system to achieve the maximum effect within a given budget and / or how to achieve a given effect with a minimum budget. Such features of hybrid intelligence systems make it possible to use them in a wide class of problems of managing socio-economic processes and socio-technical systems.

Sadovskaya E.D., Vinokurov F.N. Future with AI: careless or workless

This paper discusses the results of the exploratory stage (the first of three) of the study of social social perceptions of young people about Artificial Intelligence (AI). Our work is based on Moskovisi’s theory of social perceptions[11]. Interviews (N = 14) and observations (N = 14) were conducted, and free associations were collected on the topic of AI (N = 127). The purpose of this step is to map the common meanings associated with AI. The most prominent were the topics described below. 1) Ideas about the future with AI: the scenarios of a catastrophe with unemployment and free, creative and carefree future for humans coexist at the same time. 2) Reflections on the “non-humanity” of AI 3) The division of the areas of application of the use of AI into acceptable and unacceptable. The next steps of this study will be the analysis of the media to identify new topics, confirmation and analysis of the positioning of these topics.

Keywords: Artificial Intelligence, Human-AI interaction, Social representations.

Kokorev R.A., Lavrentieva O.N., Surkova I.B., Tolstel M.S., Trushina V.S Artificial intelligence in finance: for or against human

Progress in the creation of artificial intelligence (hereinafter - AI) is reflected both in the evolution of its definitions and in the increasing interest in its use by financial market participants around the world and regulators. From the perspective of users of financial services, one can identify certain opportunities and challenges accompanying the introduction of AI in this sphere. Despite warnings about such risks, including from representatives of the business community, large companies promote as "best practices"in the use of data recommendations that are very controversial from the point of view of the consumer. The "human"factor is of particular importance, as is a more thorough study of human behavior and decision-making that cannot be directly rationalized, including in financial consumer services, for which AI is becoming an increasingly widespread technology.

Keywords: artificial intelligence, consumer financial services, decision making.

Morosanova A. A. Economic analysis of the digital ecosystems’ participants behavior

Modern digital technologies, in particular artificial intelligence, are the basis for the existence of digital ecosystems that operate in a variety of areas and, consequently, markets. The presented study concerns the analysis of the behavior of ecosystem participants, which is supported by mathematical modeling. The findings from the analysis for various market structures indicate multiple effects, not only direct and indirect network effects, but also “feedback loops” that need to be taken into account when making business and management decisions.

Keywords: digital ecosystems, competition policy, monopolies, platforms, artificial intelligence.

Shalack V.I. Minimal logic for technology analysis

Technologies are algorithms, the result of which is the result of a sequence of external physical processes initiated by an active agent. We define the language and semantics of technologies. Also the minimal logic of technologies is axiomatized. One of the possible areas of application of the proposed language is evolutionary programming for adaptive optimization of existing technologies and the search for new ones.

Keywords: technologies, logic of technologies, natural algorithms, evolutionary programming.
