DiploCloud: Efficient and Scalable Management of RDF Data in the Cloud Abstract Despite recent advances in distributed RDF data management, processing large-amounts of RDF datain the cloud is still very challenging. In spite of its seemingly simple data model, RDF actually encodes rich and complex graphs mixing both instance and schema-level data. Sharding such data using classical techniques or partitioning the graph using traditional min-cut algorithms leads to very […]

Comments Off on Online Ensemble Learning of Data Streams with Gradually Evolved Classes
Posted in: IEEE 2017, Java
Online Ensemble Learning of Data Streams with Gradually Evolved Classes Abstract Class evolution, the phenomenon of class emergence and disappearance, is an important research topic for data stream mining. All previous studies implicitly regard class evolution as a transient change, which is not true for many real-world problems. This paper concerns the scenario where classesemerge or disappear gradually. A class-based ensemble approach, namely Class-Based ensemble forClass Evolution (CBCE), is proposed. By maintaining […]
