Closed-set-based Discovery Representative Association Rules Revisited
2011/3/2
The output of an association rule miner is often huge in practice.This is why several concise lossless representations have been proposed, such as the “essential” or “representative” rules.
Gradings on the exceptional Lie algebras $F_4$ and $G_2$ revisited
Graded algebra fine grading Weyl group, octonions Albert algebra.

All gradings by abelian groups are classified on the following al-gebras over an algebraically closed field F: the simple Lie algebra of type G2 (char F 6= 2, 3), the exceptional simple Jordan algebra...
