We study the complexity of the inclusion, equivalence, and intersection problem for simple regular expressions arising in practical XML schemas. These basically consist of the conc...
A key problem in reinforcement learning is finding a good balance between the need to explore the environment and the need to gain rewards by exploiting existing knowledge. Much ...
Efficient reachability query answering in large directed graphs has been intensively investigated because of its fundamental importance in many application fields such as XML data ...
In this paper we introduce the evolution tree - a software life-cycle model that describes software development as the continuous evolution of a software product. That is, we view...
Model trees—decision trees with linear models at the leaf nodes—have recently emerged as an accurate method for numeric prediction that produces understandable models. However,...
