Category-guided multi-interest collaborative metric learning with representation uniformity constraints

Multi-interest collaborative metric learning has recently emerged as an effective approach to modeling the multifaceted interests of a user in recommender systems. However, two issues remain unexplored. (1) There is no explicit guidance for the matching of an item against multiple interest vectors of a user. (2) The desired property of item representations with respect to their categories is overlooked, resulting in that different categories of items are mixed up in the latent space. To overcome these issues, we devise a Category-guided Multi-interest Collaborative Metric Learning model (CMCML) with representation uniformity constraints. CMCML is designed as a novel category-guided Mixture-of-Experts (MoE) architecture, where the gating network leverages the item category to guide the matching of an item against multiple interest vectors of a user, encouraging items with the same category to approach the same interest vector. In addition, we design a user multi-interest uniformity loss and a category-aware item uniformity loss: The former aims to avoid representation degeneration by enlarging the difference among multiple interest vectors of the same user; the latter is tailored to push different categories of items apart in the latent space. Quantitative experiments on Ciao, Epinions and TaFeng demonstrate that our CMCML improves the value of NDCG@20 by 12.41%, 10.89% and 10.39% respectively, compared to other state-of-the-art collaborative metric learning methods. Further qualitative analyses reveal that our CMCML yields a better representation space where items from distinct categories are arranged in different regions with high density.

Graphical contrastive learning for multi-interest sequential recommendation

Multi-interest sequential recommendation aims to deliver accurate recommendations by modeling users’ sequential behaviors and multi-faceted interests. Contrastive learning (CL) possesses an inborn advantage in distinguishing users’ multiple interests. However, existing CL-based multi-interest sequential recommenders tend to overlook the issue of data sparsity which deteriorates model performance. Graph neural network (GNN), on the other hand, has been proven as an effective measure of tackling the data sparsity problem. However, incorporating GNN into CL requires a delicate design to simultaneously achieve distinctive interest representation learning and relieve data sparsity. To address the challenges, we propose a Graphical Contrastive Learning for Multi-Interest Sequential Recommendation (GCL4MI), which first extracts user interest and constructs interest-specific graph based on item clusters and then perform graphical contrastive learning to enhance the independence between multiple interests. Furthermore, we explore different extensible CL sampling strategies with the facilitation of GNN to learn distinct interests in a high-cohesion and low-coupling manner. Extensive experiments on three real-world datasets demonstrate that our proposed GCL4MI significantly outperforms state-of-the-arts, with average lifts of 7.0%, 7.1%, and 5.8% on recall, NDCG, and HR, respectively.

Self-supervised cognitive learning for multifaced interest in large-scale industrial recommender systems

Recommender systems play a vital role in e-commerce. Existing algorithms usually learn ranking scores from a user's historical sequence, but they generally pay little attentions to mining the user's precise and varied interests to jointly optimize multiple tasks. In this study, we argue that it is crucial to formulate different user interests based on self-supervised learning (SSL) enhanced data representation for multi-scene objectives. We propose self-supervised cognitive learning (SSCL), a novel framework that can simultaneously model a user's multifaceted interest representation and linked multitask information learning. SSCL exploits SSL to enhance the value of training data. In addition, multi-interest-aggregation and multi-interest-select units are introduced and a customized gate-control model is used to optimize multiple objectives. We evaluate our framework using three real-world datasets, and our results demonstrate its effectiveness and superior performance over the state-of-the-art techniques. Compared with the baselines in three datasets, the click-through rate increased by +7.58%, and the conversion rate increased by +6.04%.

Molecular profiling of Greek native germplasm collection of Rosa canina L. for enhanced fruit extract production: a comprehensive approach utilizing neutral, gene, and exon-based markers

AbstractThe genus Rosa L. is globally distributed and Rosa canina L. is a distinguished member of multifaceted interest. Apart from the traditional uses of R. canina in folk medicine, food and cosmetic industries, or its ornamental applications, its rose hips are renowned for their functional bioactive components. Thus, identifying the genetic diversity within this species is crucial for any plant breeding project. This study employed three molecular markers namely inter simple sequence repeats; (ISSRs), start codon-targeted (SCoTs), and exon-based amplified polymorphisms; (EBAPs) to conduct the first comprehensive genetic analysis of 12 R. canina genotypes. DNA extraction, marker selection, and sequences’ amplification were performed following established protocols. The resulting genetic data were analyzed for polymorphism, diversity indices, and population structure using various statistical methods including principal component analysis (PCA), unweighted pair group method with arithmetic mean (UPGMA) clustering, and STRUCTURE analysis. The ISSR analysis revealed a high level of polymorphism (81.82%) and identified two major clusters in the UPGMA dendrogram. SCoT and EBAP markers also exhibited substantial polymorphism (74.56% and 82.11%, respectively) and formed three distinct clusters. PCA indicated a consistent pattern across markers suggesting reliable genetic grouping. STRUCTURE analysis supported the presence of three genetically uniform subpopulations (K = 3) within the studied R. canina germplasm collection. This study provided a comprehensive genetic characterization of the Greek native R. canina genebank collection. The observed genetic diversity and population structure offered valuable insights for future breeding programs targeting specific R. canina genetic clusters.

Personality, Interests, «Rules instead of Laws»: Standpoint of a Young Professor of Jurisprudence (To the 200th Anniversary of the Great Russian Educator K.D. Ushinsky)

The author analyzes K.D. Ushinsky’s views on personality, its numerous and multifaceted interests, cameralism and civil law from the little-known legal works written by K.D. Ushinsky in the first years after graduating from the Faculty of Law of Moscow University, namely three years of his serving as a professor of the Demidovsky Law Lyceum in Yaroslavl. In this regard, the general conditions of teaching at that higher educational institution and the range of disciplines taught, the few surviving sources of Ushinsky’s lecture activity of this period and his speech «On cameral education» at the solemn meeting of the Demidovsky Lyceum are briefly considered. Special attention is given to Ushinsky’s astute conclusion that convenient rules took the place of laws in German cameralistics of that time. This opinion is especially relevant today, because it shows that the desire of Western countries to start living not according to the norms of international law, but according to the rules established by them, did not arise today. The modern political, diplomatic, legal, and economic reality is literally oversaturated with facts of illegal sanctions, asset freezes, property seizures, and other illegal actions of the United States and a number of other Western countries against Russia and other independent states, as well as citizens of these states. Ushinsky’s analysis of German cameralism clearly shows that the use by Western countries of «rules convenient for them» instead of laws is by no means a modern «invention», but a constantly developing process, the foundation of which was laid by Western political and legal thought several centuries ago.

Name from the Past: Nikolai Khristianovich Vessel in the Service of Russian Education

State policy in the field of education, as a rule, is dictated by the demands of the time, any changes in this extremely important area are not immediately noticeable. The results of innovations carry a delayed action and, appearing gradually, sometimes lead to irreparable consequences. Structuring the education system should be one of the state’s priorities. Throughout history, the education system of our country has repeatedly undergone significant transformations, in this regard, it is interesting to turn to the historical experience in the educational sphere accumulated by previous generations. Today, the interest of researchers in the scientific and pedagogical heritage of Russian public figures has significantly increased. The name of Nikolai Khristianovich Vessel, long forgotten, belongs to that plethora of brilliant Russian teachers of the second half of the XIX century, whose works are in demand today. The purpose of the article is to introduce into scientific circulation new biographical data found on the pages of his unpublished and little-known works and to present N.Kh. Vessel not only as an expert in the field of pedagogy, but also as a person distinguished by broad multifaceted interests, in particular in the field of finance.

Індивідуальні та соціальні константи ідентичності: філософсько правове моделювання їх взаємодії

The article outlines meaningful priorities that reveal the essence of identity, in particular, individual and social constants of identity are highlighted by means of philosophical and legal modeling of their interaction. It has been proven that the concept of identity has the potential of one of the most powerful concepts in today's globalized society. The phenomenon of identity is a unique prism through which the main spheres of human existence are understood, analyzed and interpreted. The actualization of identity as a social problem can be traced at all levels: household, state, political, religious, gender, etc. The author found out that the concept of identity is neither an obvious nor a homogeneous construct, which has an undeniable meaning and value in various socio-cultural contexts. The constant and multifaceted interest in the phenomenon of identity gives reason to assert the incompleteness and openness of the discourse on identity as a category of philosophical and legal science. Therefore, today there is an urgent need to determine the prospects of further research in this direction, primarily through the study of two aspects: first, the methods of defining and evaluating the phenomenon of identity in small and large social groups in the conditions of a growing level of legal and social polarization and mistrust of various social institutions (state, legal, social) and the implementation of socially important decisions, that is, the transfer of rhetoric about identity from the individual-psychological level to the social-cultural and national level; secondly, the development of approaches to distinguishing "real" identity, its authentic dimension from "situational" identities in the conditions of opportunism of atomized societies, an example of which is currently Ukraine.

Личные библиотеки А. Шёнберга и А. Берга как источник изучения творческой биографии

Composers’ personal libraries began to be the objects of research relatively recently, only about a hundred years ago. Meanwhile, it presents a valuable source for research of composers’ artistic biographies, which bears the imprint of the personalities both of the owner of the book collection and of his or her entire generation. The library makes it possible to evaluate the tastes and the predilections of the composer in question, helps reconstruct his or her artistic ideas, at times contains various types of marginalia, which in modern source studies have acquired the status of texts. The fate of Arnold Schönberg’s library and that of his student Alban Berg unfolded differently from each other. Schönberg was not a bibliophile, his personal library served him as a working tool and reflected his multifaceted interests in various fields of knowledge. Despite his numerous relocations, his library retained its integrity. Schönberg himself compiled a partial inventory of it, arranging the books in accordance with his hierarchy of values. The systematic study of his book collection began at the Arnold Schönberg Institute in Los Angeles and was continued at the Arnold Schönberg Center after his archive was moved to Vienna. Of particular value in the Schönberg library are his polemical marginalia, in which he conducts imaginary discussions with contemporaries: Hans Pfitzner, Ferruccio Busoni, Heinrich Schenker and others. They complement the corpus of Schönberg’s published and unpublished music theory texts. Berg’s library is up to the present day located in the composer’s Vienna apartment. Researchers received access to his books at a relatively late date, after the death of Berg’s widow Helena in 1976. The systematization and cataloging of the Berg Library has not been finished up to the present time. Berg came from an antiquarian family, he inherited his bibliophilia from his father. Already from a young age, he perceived his personal library a means of cognition of himself and the world, as evidenced by the large-scale collection of quotations Von der Selbsterkenntnis [About Self-Cognition] compiled by him. Berg, like Schönberg, had a habit of polemizing with opponents in the form of marginalia (such is his polemics with Wilhelm Krug in his book Neue Musik). Of great interest to researchers are Berg’s work copies of Georg Büchner’s dramatic play Wozzeck by, as well as Frank Wedekind’s dilogy of plays Erdgesit [The Spirit of the Earth] and Die Büchse der Pandora [Pandora’s box] which were used by Berg during his work on the librettos for each of his two operas. They make it possible to reconstruct the composer’s creative process and contain valuable instructions regarding the dramaturgy and compositional form, the protagonists’ characteristic features, as well as the formal structures of separate sections of the operas. The ongoing process of digitization of Schönberg’s and Berg’s archives makes it possible for us to hope that researchers on all the continents will be granted access to personal libraries of these two composers, as well as those of other composers.

Recommending Profiles To Social Event Participation In Online Social Network Service Applications Using Deep Learning Techniques

Nowadays, organizing online Social events is growing especially in current pandemic situation due to corona. Thus social network services helps to organize the event oriented online social gathering. The events discussed on social networks can be associated with topics, locations, and time periods. Various literatures have employed clustering mechanism to group the profiles of the user of social networking applications. More research has been carried out in event based online network services as existing models leads to scalability and sparsity problems. Event-based online social networks are used to maintain interest-based groups with high relevancy rate, recommendation quality and predictive accuracy. In order to achieve the above goal, in this paper, we propose a novel framework named as Deep Influence Predict (DIP) which explores the features of Recurrent Neural Network in order identify the target or potential users through different patterns and behaviours of the profile on the social networking service applications. It learns multiple levels of representations and abstractions of the latent data through individual participation record. Further, it extracts the extrinsic and intrinsic properties of the profiles on their social connections and social effects. Specifically, it identifies the distinguishing social groups with different topics and categories as multifaceted interest in iterative process. Finally decision of recommendation for the event is integrated on outcomes of user behaviour model through personnel impact, social relation and equilibrium. Evaluation of the proposed model through various case studies has been implemented using hadoop architecture and validated across various measures such as accuracy on precision, Recall and f measure along scalability and Execution time.

MulSimNet: A multi-branch sub-interest matching network for personalized recommendation

Personalized recommendation serves as an indispensable functionality in many online services, where the key is to model the user’s preference based on past user-item interactions. Many well-known models learn a latent vector for each user and each item. Nevertheless, a single latent vector might not be able to well represent a user’s multifaceted interests revealed by the wide variety of items consumed by him/her. In this paper, we present a flexible framework named Multi-branch Sub-interest matching Network (MulSimNet) for personalized recommendation. Each user is explicitly represented by multiple sub-interest vectors as well as a general interest vector, and an item is matched against these vectors through different branches, where each branch is realized by appropriate neural networks. The compatibility scores output by multiple sub-interest matching branches are first aggregated via the max operator, which is then fused with the output of the general interest matching branch to estimate the user’s affinity with the item. A comprehensive set of experiments on benchmark datasets demonstrate the effectiveness of the proposed framework in fully capturing the user’s multifaceted interests and yielding better top-N recommendations.

L’architetto integrale and Gustavo Giovannoni’s role in education and cultural dissemination

ABSTRACT The engineer Gustavo Giovannoni made a decisive contribution to the development of a new professional figure: l’architetto integrale, best described as the all encompassing architect. Under this broad indicative title he envisioned a variety of operational skills that combine the roles of architect, urban planner, historian and restorer. In the context of these multifaceted interests, the essay investigates the centrality of scientific dissemination for Giovannoni. For the sake of accuracy, the term cultural dissemination should be used, as it better conveys the idea of a 360-degree educational project designed for both learned audiences (with a solid scientific background) and non-specialists generally interested in Italian architectural culture, planning history and landscape. Giovannoni’s careful targeting of different audiences is discernable in periodicals and other media chosen to transmit his ideas, from scientific journals to newspapers and national radio programmes. The present essay seeks to investigate the relationship Giovannoni had with the media and his participation in the amateur activities of various cultural and sporting associations, directed towards increasing awareness of Italy’s historical cities and the territory’s natural beauty.

Life for onomastics: A scientific portrait of Iryna Mykhailivna Zhelіezniak

The article characterizes the scientific achievements of the famous Ukrainian linguist I. M. Zheliezniak (April 25, 1932 — June 24, 2020) in various areas of national onomastics — anthroponymics, oikonymics, hydronymics, microtoponymics. The focus is on the multifaceted interests of the scientist: structural and semantic features of Old Slavic composite names, the origin of Ukrainian surnames, the etymology of Ukrainian and non-Slavic potamonyms, oiko nyms, oronyms, the formation of the Kyiv microtoponymicon, Ukrainian-non-Slavic (Ukrainian-South Slavic) hydronyms parallels, the problem of Slavic ethnogenesis through the prism of pro per names. The works of Iryna Mykhailivna, important for domestic onomastics, from various onomastics branches are described. Her organizational activities are outlined, in particular, as the head (1985—2002) of the first group of onomastics within the dialectology and onomastics sector of the Potebnia Institute of Linguistics of the Academy of Sciences of the Ukrainian SSR, and later the Department of Onomastics within the Institute of the Ukrainian Language of the National Academy of Sciences of Ukraine. Iryna Mykhailivna was the inspirer and organizer of onomastic seminars at the Potebnia Institute of Linguistics of the Academy of Sciences of the Ukrainian SSR and the Institute of the Ukrainian Language of the National Academy of Sciences of Ukraine, she was a scientific editor of collections of scientific works, known not only in Ukraine, but also abroad, and the author of onomastic articles in three editions of the Ukrainian language encyclopedia. The article emphasizes the importance of the scientific ideas of I. M. Zheliezniak for modern and future scientists-onomastics. The scientist’s contribution to the formation of Ukrainian onomastic science is updated. Keywords: anthroponyms, hydronyms, onomastics, onomastic studies, I. M. Zheliezniak

Исторический опыт формирования российско-финляндской границы: теоретические аспекты становления (и формирования) международно-правового регулирования

The problems of the historical aspects of the formation of interstate borders, which continue to be the focus of attention of representatives of the scientific and practical community, are analyzed. The above is due, among other things, to the specifics of the geopolitical position of individual border territories, which were the subject of disagreements and disputes. From the standpoint of the theory and methodology of law, the problems around state borders are dictated by the growing objective and natural needs of states and the legally formalized directions of the latter's policy in this area. Attempts have been made to consider some historical aspects of the formation of the legal basis of the Russian-Finnish border. Against the backdrop of increased rivalry between key centers of power, growing contradictions and dynamic changes in international relations, a new rethinking of the historical process of legal registration of the establishment of the border between the two countries will become of particular relevance. An analysis of the early historical patterns and the genesis of the formation of the interstate border makes it possible to build it in line with the revision and reassessment of certain aspects of the logic of the formation of the border space within the framework of the historical and legal process. It is concluded that in modern conditions, on the one hand, the readiness to develop in-depth cooperation within the framework of the emerging new model of behavior in this area and, on the other hand, the moods traditionally taking place in certain political and public circles of Finland regarding the return of the lost Karelian lands determine the use of the most stable border regimes and adequate political and legal mechanisms, procedures to avoid the negative impact of the factor of increasing the process of militarization of the border and individual risks. In the context of a possible change in the policy of the two countries, the theory of legal regulation of the issues under study is of great importance, without which it seems impossible to achieve a balance of the multifaceted interests of states.

Document Representation and Query Expansion Models for Blog Recommendation

We explore several different document representation models and two query expansion models for the task of recommending blogs to a user in response to a query. Blog relevance ranking differs from traditional document ranking in ad-hocinformation retrieval in several ways: (1) the unit of output (the blog) is composed of a collection of documents (the blog posts) rather than a single document, (2) the query represents an ongoing and typically multifaceted interest in the topic rather than a passing ad-hoc information need and (3) due to the propensity of spam, splogs, and tangential comments, the blogosphere is particularly challenging to use as a source for high-quality query expansion terms. We address these differences at the document representation level, by comparing retrieval models that view either the blog or its constituent posts as the atomic units of retrieval, and at the query expansion level, by making novel use of the links and anchor text in Wikipedia1 to expand a user's initial query. We develop two complementary models of blog retrieval that perform at comparable levels of precision and recall. We also show consistent and significant improvement across all models using our Wikipedia expansion strategy.

Theodor Meynert (1833–1892): Famous brain-anatomist and poet

This paper focuses on the lesser-known side of the famous neuropathologist, anatomist, and psychiatrist Theodor Meynert (1833-1892): Meynert as a poet. Meynert decided to become a doctor late in life, a decision that required him to give up on having a career as a writer. This analysis outlines that Meynert, as a scientist, was significantly shaped by his multifaceted interests and surrounding environment. It refers to previously unknown archival materials and especially letters that gives new insights into his multifactored personality. Thus, as this paper argues, his poetic affinity is of great importance to understanding his work.

Who's afraid of epigenetics? Habits, instincts, and Charles Darwin\u2019s evolutionary theory

Our paper aims at bringing to the fore the crucial role that habits play in Charles Darwin’s theory of evolution by means of natural selection. We have organized the paper in two steps: first, we analyse value and functions of the concept of habit in Darwin's early works, notably in his Notebooks, and compare these views to his mature understanding of the concept in the Origin of Species and later works; second, we discuss Darwin’s ideas on habits in the light of today’s theories of epigenetic inheritance, which describe the way in which the functioning and expression of genes is modified by the environment, and how these modifications are transmitted over generations. We argue that Darwin’s lasting and multifaceted interest in the notion of habit, throughout his intellectual life, is both conceptually and methodologically relevant. From a conceptual point of view, intriguing similarities can be found between Darwin’s (early) conception of habit and contemporary views on epigenetic inheritance. From a methodological point of view, we suggest that Darwin’s plastic approach to habits, from his early writings up to the mature works, can provide today’s evolutionary scientists with a viable methodological model to address the challenging task of extending and expanding evolutionary theory, with particular reference to the integration of epigenetic mechanisms into existing models of evolutionary change. Over his entire life Darwin has modified and reassessed his views on habits as many times as required by evidence: his work on this notion may represent the paradigm of a habit of good scientific research methodology.

Micrography, Medleys, and marks: the visual discernment of text in the calligraphy collection of Samuel Pepys

Samuel Pepys’s calligraphy collection comprises numerous textual fragments pasted and bound into three volumes, which together document a history of handwriting and textual forms. The calligraphy volumes evidence a deep and multifaceted interest in visual criticism trained on the written word within Pepys’s social and intellectual milieu. In particular, micrographic texts and trompe l’œil ‘Medley’ images offered educated gentleman a body of delightfully curious material on which they could practise and hone communal, comparative, and repeatable modes of critical observation. The article also provides new evidence to show that early Medley images emerged in tandem with the rise of calligraphic collections and were developed by penmasters in collaboration with the interests of seventeenth-century collectors who were fascinated by the impact that optical devices, drawing instruments, and developments in printing techniques could have on the aesthetic rendering of text. From the mid-1690s to the early eighteenth century, the appearance of the written word played a vital role in discussions about visual discernment within English intellectual circles.
