Curriculum Learning for Heterogeneous Star Network Embedding via Deep Reinforcement Learning

TL;DR: This paper proposes an approach based on deep reinforcement learning for node representation learning in heterogeneous star networks, which leverages LSTM models to encode states and further estimate the expected cumulative reward of each state-action pair.
Journal ArticleDOI

Recurring and Novel Class Detection Using Class-Based Ensemble for Evolving Data Stream

TL;DR: This paper defines a novel ensemble technique “class-based” ensemble which replaces the traditional “chunk- based” approach in order to detect the recurring classes in data streams and proves the superiority of both “ class-based" ensemble method over state-of-art techniques via empirical approach on a number of benchmark data sets.
Proceedings ArticleDOI

TaxoClass: Hierarchical Multi-Label Text Classification Using Only Class Names

TL;DR: This paper proposes a novel HMTC framework, named TaxoClass, which calculates document-class similarities using a textual entailment model, identifies a document’s core classes and utilizes confident core classes to train a taxonomy-enhanced classifier, and generalizes the classifier via multi-label self-training.
Proceedings ArticleDOI

TaxoExpan: Self-supervised Taxonomy Expansion with Position-Enhanced Graph Neural Network

TL;DR: Wang et al. as discussed by the authors propose a self-supervised framework, named TaxoExpan, which automatically generates a set of query concept, anchor concept pairs from the existing taxonomy as training data.

Modeling Probabilistic Measurement Correlations for Problem Determination in Large-Scale Distributed Systems

TL;DR: The proposed transition probability model based on markov properties to characterize pair-wise measurement correlations can discover both the spatial and temporal correlations in the distributed system and thus can successfully represent the system normal profiles.
