Relational rule learning is typically used in solving classification and prediction tasks. However, it can also be adapted to the description task of subgroup discovery. This paper takes a propositionalization approach to relational subgroup discovery (RSD), based on adapting rule learning and first-order feature construction, applicable in individualcentered domains. It focuses on the use of c...

My aim in this lecture will be to try to convince you that the classification of the finite simple groups is nearing its end. This is, of course, a presumptuous statement, since one does not normally announce theorems as "almost proved". But the classification of simple groups is unlike any other single theorem in the history of mathematics, since the final proof will cover at least 5,000 journ...

The extensive diversity of membrane lipids is rarely appreciated by cell and molecular biologists. Although most researchers are familiar with the three main classes of lipids in animal cell membranes, few realize the enormous combinatorial structural diversity that exists within each lipid class, a diversity that enables functional specialization of lipids. In this brief review, we focus on on...

Some of the major outstanding problems in biology are related to issues of emergence and evolution. These include: (1) how do populations of organisms traverse their adaptive landscapes? (2) what is the relation between adaptedness and tness? (3) the formation of multi-cellular organisms from basic units or cells. In this paper we study these issues using a model which is both general and simpl...
