Link Prediction Regression for Weighted Co-authorship Networks
P. 667-677.
Gerasimova O., Makarov I.
In this paper, we study the problem of predicting quantity of collaborations in co-authorship network. We formulated our task in terms of link prediction problem on weighted co-authorship network, formed by authors writing papers in co-authorship represented by edges between authors in the network. Our task is formulated as regression for edge weights, for which we use node2vec network embedding and new family of edge embedding operators. We evaluate our model on AMiner co-authorship network and showed that our model of network edge representation has better performance for stated regression link prediction task.

In this paper, we study the problem of predicting collaborations in co-authorship network. We formulated our task in terms of link prediction problem on weighted co-authorship network, in which authors play the role of nodes, and weighted edges connecting two authors are formed by storing either a number or quality metric of research papers co-authored ...

In this paper, we study network feature engineering for the problem of future co-author recommendation, also called collaborator recommender system. We present a system, which uses authors' research interests and existing collaboration information to predict missing and most probable in the future links in the co-authorship network. The recommender system is stated as a link ...

The paper briefly introduces multiple classifier systems and describes a new algorithm, which improves classification accuracy by means of recommendation of a proper algorithm to an object classification. This recommendation is done assuming that a classifier is likely to predict the label of the object correctly if it has correctly classified its neighbors. The process ...

Network embedding has become a very promising technique in analysis of complex networks. It is a method to project nodes of a network into a low-dimensional vector space while retaining the structure of the network based on vector similarity. There are many methods of network embedding developed for traditional single layer networks. On the other ...

Графовые метрики – популярный подход для клас- сификации структурных коннектомов, графов опи- сывающих структурные связи между различными участками мозга. В нашей работе мы предлагаем считать эти метрики на стохастических матри- цах случайных блужданий этих графов. При этом часть этих метрик мы предлагаем считать на логарифмах элементов матриц, чтобы сохранить физический смысл вероятностей перехода меж- ду ...

Words of any language are to some extent related thought the ways they are formed. For instance, the verb ‘exempl-ify’ and the noun ‘example-s’ are both based on the word ‘example’, but the verb is derived from it, while the noun is inflected. In Natural Language Processing of Russian, the inflection is satisfactorily processed; however, ...

In this paper we focus on the problem of multi-label image recognition for visually-aware recommender systems. We propose a two stage approach in which a deep convolutional neural network is firstly fine-tuned on a part of the training set. Secondly, an attention-based aggregation network is trained to compute the weighted average of visual features in ...

Многие графовые метрики основаны на предположении, что веса графа представляют расстояния между вершинами, которые мы можем складывать. Если считать эти метрики для стохастических матриц случайного блуждания на графе, то физический смысл вероятностей перехода между вершинами теряется (поскольку вероятности переходов перемножаются, а не складываются). Мы предлагаем решать эту проблему использованием отрицательных логарифмов весов ребер. Используя этот ...
