As a generalized form of multi-class classification, multilabel classification allows each sample to be associated with multiple labels. This task becomes challenging when the number of labels bulks up, which demands a high efficiency. Many approaches have been proposed to address this problem, among which one of the main ideas is to select a subset of labels which can approximately span the or...

Many web-based application areas must infer label distributions starting from a small set of sparse, noisy labels. Previous work has shown that graph-based propagation can be very effective at finding the best label distribution across nodes, starting from partial information and a weightedconnection graph. In their work on video recommendations, Baluja et al. showed high-quality results using ...

We present a novel and scalable label embedding framework for large-scale multi-label learning a.k.a ExMLDS (Extreme Multi-Label Learning using Distributional Semantics). Our approach draws inspiration from ideas rooted in distributional semantics, specifically the Skip Gram Negative Sampling (SGNS) approach, widely used to learn word embeddings for natural language processing tasks. Learning s...

Community detection is one of the primary problems in social network analysis and this problem has more challenges attributed networks. The purpose community networks to discover communities with not only homogeneous node properties but also adherent structures. Although been extensively studied, large a number attributes remains vital challenge. To address challenge, paper novel method develop...

In many applications such as recommender systems and multi-label learning the task is to complete a partially observed binary matrix. Such PU learning (positive-unlabeled) problems can be solved by one-class matrix factorization (MF). In practice side information such as user or item features in recommender systems are often available besides the observed positive user-item connections. In this...

A new unsupervised feature selection method, i.e., Robust Unsupervised Feature Selection (RUFS), is proposed. Unlike traditional unsupervised feature selection methods, pseudo cluster labels are learned via local learning regularized robust nonnegative matrix factorization. During the label learning process, feature selection is performed simultaneously by robust joint l2,1 norms minimization. ...

There are two examples given in section 3.3 of the paper (pages 349– 352). The first of the two examples is a three matrix product cycle in four states. Here one may label this three matrix product cycle by assigning letters to each matrix. Let the cycle be . . .ABC . . . . A stationary cycle of state probability distributions and two state paths are given that do correspond to the product cycl...

Many modern multiclass and multilabel problems are characterized by increasingly large output spaces. For these problems, label embeddings have been shown to be a useful primitive that can improve computational and statistical efficiency. In this work we utilize a correspondence between rank constrained estimation and low dimensional label embeddings that uncovers a fast label embedding algorit...
