We report on a new experimental analysis of high-order entropy-compressed suffix arrays, which retains the theoretical performance of previous work and represents an improvement in...
Abstract. A new realization of a space-efficient deque is presented. The data structure is constructed from three singly resizable arrays, each of which is a blockwiseallocated pil...
Our focus is on designing adaptable agents for highly dynamic environments. Wehave implementeda reinforcement learning architecture as the reactive componentof a twolayer control ...
In TREC 2007, we participate in four tasks of the Blog and Enterprise tracks. We continue experiments using Terrier1 [14], our modular and scalable Information Retrieval (IR) plat...
