On Dynamic Weighting of Data in Clustering with K-Alpha Means
Although many methods of refining initialization have appeared, the sensitivity of K-Means to initial centers is still an obstacle in applications. In this paper, we investigate a...

On the Topological Complexity of Weakly Recognizable Tree Languages
We show that the family of tree languages recognized by weak alternating automata is closed by three set theoretic operations that correspond to sum, multiplication by ordinals <...

Undoing Dynamic Typing (Declarative Pearl)
We propose undoable versions of the projection operations used when programs written in higher-order statically-typed languages interoperate with dynamically typed ones, localizing...
