How to Assess Students Knowledge in the Age of AI
A researcher at HSE University has proposed a flowchart to help lecturers decide how to assess students who use artificial intelligence. It shows where the use of AI should be restricted and where it can be incorporated into the learning process. The article has been published in IT Professional.

‘Balkan Hospitality Opens Doors: Studying Dialects on the Verge of Extinction
You cannot study spoken dialects from books. Instead, you need to go to a village, seek out its elders, and earn the trust of local residents before you can record hours of spontaneous stories. This is how Natalia Muravleva, Associate Professor at the Faculty of Humanities, conducts her research. Her internship in Serbia continued her long-standing study of dialects spoken by Macedonian settlers. In this interview, she discusses how diaspora cultural centres help researchers reach informants, why native speakers need to be interviewed only in their own language (otherwise, as she puts it, they may 'break'), and how a single field season helped her finalise her monograph. She also shares warm memories of autumn in Belgrade and of colleagues with whom grammar can be discussed in three languages at once.

Scientists Train Neural Network to Generate Process Plans from 3D Models
Researchers at the HSE FCS AI and Digital Science Institute have developed CAD2TechSpec, a framework that converts 3D models of mechanical parts into machining process plans—step-by-step instructions for machine tools. The solution aims to reduce the time required for the design and preparation of technical process documentation in mechanical engineering, aircraft manufacturing, and other high-tech industries. The study findings have been published in PeerJ Computer Science.

Turning Krimp into a Triclustering Technique on Sets of Attribute-Condition Pairs that Compress

P. 558–569.
Ignatov D. I., Yurov M.

Mining ternary relations or triadic Boolean tensors is one of the recent trends in knowledge discovery that allows one to take into account various modalities of input object-attribute data. For example, in movie databases like IMBD, an analyst may find not only movies grouped by specific genres but see their common keywords. In the so-called folksonomies, users can be grouped according to their shared resources and used tags. In gene expression analysis, genes can be grouped along with samples of tissues and time intervals providing comprehensible patterns. However, pattern explosion effects even with one more dimension are seriously aggravated. In this paper, we continue our previous study on searching for a smaller collection of “optimal” patterns in triadic data with respect to a set of quality criteria such as patterns’ cardinality, density, diversity, coverage, etc. We show how a simple data preprocessing has enabled us to use the frequent itemset mining algorithm Krimp based on MDL-principle for triclustering purposes.

Mixed Integer Programming for Searching Maximum Quasi-Bicliques

This paper is related to the problem of finding the maximal quasi-bicliques in a bipartite graph (bigraph). A quasi-biclique in the bigraph is its “almost” complete subgraph. The relaxation of completeness can be understood variously; here, we assume that the subgraph is a \(\gamma \)-quasi-biclique if it lacks a certain number of edges to form ...

Multimodal Clustering for Community Detection
Ignatov D. I., Semenov A., Комиссарова Д. В. et al., , in: Formal Concept Analysis of Social Networks.: Springer, 2017. Ch. 4 P. 59–96.
Multimodal clustering is an unsupervised technique for mining interesting patterns in n-ary relations or n-mode networks. Among different types of such generalised patterns one can find biclusters and formal concepts (maximal bicliques) for two-mode case, triclusters and triconcepts for three-mode case, closed n-sets for n-mode case, etc. Object-attribute biclustering (OA-biclustering) for mining large binary datatables (formal contexts or two-mode ...

Putting OAC-triclustering on MapReduce

In our previous work an efficient one-pass online algorithm for triclustering of binary data (triadic formal contexts) was proposed. This algorithm is a modified version of the basic algorithm for OAC-triclustering approach; it has linear time and memory complexities. In this paper we parallelise it via map-reduce framework in order to make it suitable for big datasets. The results of ...

Triadic Formal Concept Analysis and triclustering: searching for optimal patterns
Ignatov D. I., Gnatyshak D. V., Sergei O. Kuznetsov et al., Machine Learning 2015 Vol. 101 No. 1 P. 271–302
This paper presents several definitions of “optimal patterns” in triadic data and results of experimental comparison of five triclustering algorithms on real-world and synthetic datasets. The evaluation is carried over such criteria as resource efficiency, noise tolerance and quality scores involving cardinality, density, coverage, and diversity of the patterns. An ideal triadic pattern is a totally dense ...

Однопроходный алгоритм трикластеризации
Гнатышак Д. В., Научно-техническая информация. Серия 2: Информационные процессы и системы 2015 № 2 С. 16–30
В связи с продолжающимся ростом популярности области больших данных все более активно ставится вопрос о создании эффективных алгоритмов с низкой временной сложностью и возможностью параллелизации. Целью данной работы было создание эффективного однопроходного алгоритма трикластеризации бинарных данных, пригодного для использования в области больших данных. В результате был получен однопроходный линейный онлайн-алгоритм OAC-трикластеризации (трикластеризации объект-признак-условие). Помимо того, ...

В работе представлен оригинальный метод трикластеризации, который использовался для поиска «плотных» троек вида (посетители, тэги, ресурсы) при анализе данных сервиса социальных закладок Bibsonomy. Предложенный метод является универсальным для анализа любых тримодальных данных, описываемых тернарными отношениями, и служит вычислительно эффективной альтернативой поиску трипонятий (в смысле анализа формальных понятий) и построению айсбергов трирешёток. ...

В работе предложен новый подход к трикластеризации трехмерных бинарных данных. Трикластер определен в терминах триадического анализа формальных понятий (Triadic Formal Concept Analysis) как плотное тримножество тернарного отношения Y между объектами, признаками и условиями. Такое определение является ослаблением определения трипонятия и дает возможность найти все трикластеры и трипонятия, содержащиеся в трикластерах больших наборов данных. Данный подход ...

A novel approach to triclustering of a three-way binary data is proposed. Tricluster is defined in terms of Triadic Formal Concept Analysis as a dense triset of a binary relation Y , describing relationship between objects, attributes and conditions.
