A Mnemonic for Representative Element Groups

Are the epilepsy representative groups truly representative?

This is a timely piece of work given the emphasis being placed on the patient in the process of health policy formulation and service design and commissioning. Duncan et al. therefore ask a very relevant and important question about the validation of patient and service user involvement and in particular the qualification of representative groups that purport to voice the views of people with a...

Uncovering Representative Groups in Multidimensional Projections

Multidimensional projection-based visualization methods typically rely on clustering and attribute selection mechanisms to enable visual analysis of multidimensional data. Clustering is often employed to group similar instances according to their distance in the visual space. However, considering only distances in the visual space may be misleading due to projection errors as well as the lack o...

A representation for some groups, a geometric approach

‎In the present paper‎, ‎we are going to use geometric and topological concepts‎, ‎entities and properties of the‎ ‎integral curves of linear vector fields‎, ‎and the theory of differential equations‎, ‎to establish a representation for some groups on $R^{n} (ngeq 1)$‎. ‎Among other things‎, ‎we investigate the surjectivity and faithfulness of the representation‎. At the end‎, ‎we give some app...
