Approximate Tree Kernels
Convolution kernels for trees provide simple means for learning with tree-structured data. The computation time of tree kernels is quadratic in the size of the trees, since all pa...

A Refined Difference Field Theory for Symbolic Summation
In this article we present a refined summation theory based on Karr's difference field approach. The resulting algorithms find sum representations with optimal nested depth. ...

A modest proposal for curing the public field phobia
Field accessor methods have become a ubiquitous feature of object-oriented programming. The definition and use of such methods promote code bloat and an unnatural expression style...

Mining Frequent Closed Unordered Trees Through Natural Representations
Abstract. Many knowledge representation mechanisms consist of linkbased structures; they may be studied formally by means of unordered trees. Here we consider the case where labels...
