The article is devoted to the study of the rhythm of verse and prose by N.A. Nekrasov using quantitative methods. In this work, the poet's poems written in iambic tetrameter are considered, their correspondence to the trends in the verse of the 1840s-1880s is analyzed. Prose analysis is carried out by constructing and comparing a ...

Relevance and diversity are critical objectives in modern information retrieval (IR), particularly in recommender systems. Achieving a balance between relevance (exploitation) and diversity (exploration) optimizes user satisfaction and business goals such as catalog coverage and novelty. While existing post-processing reranking methods address this trade-off, they usually rely on greedy strategies, leading to suboptimal outcomes for ...

Time to Split: Exploring Data Splitting Strategies for Offline Evaluation of Sequential Recommenders
Gusak D., Volodkevich A., Klenitskiy A. et al., , in: RecSys '25: Proceedings of the Nineteenth ACM Conference on Recommender Systems.: ACM, 2025. P. 874–883.
Modern sequential recommender systems, ranging from lightweight transformer-based variants to large language models, have become increasingly prominent in academia and industry due to their strong performance in the next-item prediction task. Yet common evaluation protocols for sequential recommendations remain insufficiently developed: they often fail to reflect the corresponding recommendation task accurately, or are not aligned ...

In this work, we present a fast and effective Linear approach for updating recommendations in a scalable graph-based recommender system UltraGCN. Solving this task is extremely important to maintain the relevance of the recommendations under the conditions of a large amount of new data and changing user preferences. To address this issue, we adapt the ...

Recent studies have demonstrated the potential of hyperbolic geometry for capturing complex patterns from interaction data in recommender systems. In this work, we introduce a novel hyperbolic recommendation model that uses geometrical insights to improve representation learning and increase computational stability at the same time. We reformulate the notion of hyperbolic distances to unlock additional ...

This article explores the metrics of poems written by the poet Antonina A. Kymytval. The meter of the verse, written in Chukchi, has not been explored before. I collected a corpus of 40 texts and glossed them manually. After that, I analyzed the number of syllables in a line and the placement of word boundaries, stress, and syllables ...

We present a new movie and TV show recommendation dataset collected from the real users of MTS Kion video-on-demand platform. In contrast to other popular movie recommendation datasets, such as MovieLens or Netflix, our dataset is based on the implicit interactions registered at the watching time, rather than on explicit ratings. We also provide rich ...

Simulators for recommender systems are widely used for recommender systems performance evaluation and feedback loop effects analysis. Existing simulators often propose inflexible pipelines, are focused on narrow research tasks, or are not adapted to work with industrial large data volumes. To address these challenges, we developed the Sim4Rec simulation framework. The Sim4Rec models key aspects ...

Over the last several decades, recommender systems have become an integral part of both our daily lives and the research frontier at machine learning. In this survey, we explore various approaches to developing simulators for recommendation systems, especially for modeling the user response function. We consider simple probabilistic models, approaches based on generative adversarial networks, ...

Sequential recommender systems are an important and demanded area of research. Such systems aim to use the order of interactions in a user’s history to predict future interactions. The premise is that the order of interactions and sequential patterns play an essential role. Therefore, it is crucial to use datasets that exhibit a sequential structure ...

Knowledge-aware recommender systems incorporate side information to improve recommendation performance. The authors of new algorithms are usually focused on developing new ideas behind the proposed methods and comparing their models with existing knowledge-aware recommender models. Meanwhile, some commonly used state-of-the-art general top-n recommender models are ignored as potential baselines. In this study, we compare previously ...

В статье исследуется метрический репертуар Игоря Чиннова (1909–1996), одного из наиболее виртуозных русских поэтов второй половины XX века. Приводится общая количественная характеристика используемых Чинновым метров (и других формальных параметров стиха) и анализируется их распределение по разным периодам творчества поэта. Также показано, что выделяемые в его творчестве три периода (условно, поэтика «парижской ноты», поэтика барокко и поэтика ...

Recommender systems have become increasingly popular for providing personalized recommendations to users. Recent studies have shown that transformer-based approaches can enhance the performance of these systems. However, these models usually consider the sequence of past user interactions and do not take into account the time of prediction. In this paper, we address this issue by ...
