In this work we investigate some computational aspects of the eigenvalue calculation with edge elements; those include: the importance of the grid generator and nodeedge numbering. As the examples show, the sparse structure of the mass and stiffness matrices is highly influenced by the edge numbering. Tetrahedral grid generators are mainly designed for nodal based finite elements so an edge num...

Learning by erasing means the process of eliminating potential hypotheses from further consideration thereby converging to the least hypothesis never eliminated. This hypothesis must be a solution to the actual learning problem. The capabilities of learning by erasing are investigated in relation to two factors: the choice of the overall hypothesis space itself and what sets of hypotheses must ...
