FEDRA: A Fast and Efficient Dimensionality Reduction Algorithm

Contemporary data-intensive applications generate large datasets of very high dimensionality. Data management in high-dimensional spaces presents problems, such as the degradation of query processing performance, a phenomenon also known as the curse of dimensionality. Dimensionality reduction (DR) tackles this problem, by efficiently embedding data from high dimensional to lower dimensional spa...

Fedra: Query Processing for SPARQL Federations with Divergence

Data replication and deployment of local SPARQL endpoints improve scalability and availability of public SPARQL endpoints, making the consumption of Linked Data a reality. This solution requires synchronization and specific query processing strategies to take advantage of replication. However, existing replication aware techniques in federations of SPARQL endpoints do not consider data dynamici...

Folie à Trois à Lubumbashi: à propos d’un cas

Le trouble psychotique partagé est une entité psychiatrique rare caractérisée par la transmission des idées délirantes d’un patient dit "inducteur", à un autre dit "induit", tous vivant en association proche, dans un milieu clos et isolé, partageant des idées délirantes sur le même thème. Nous vous rapportons un cas clinique de "folie à trois" mettant en jeu un délire de persécution à mécanisme...
