Joint Optimization of Cost and Coverage of Query Plans in Data Integration
Existing approaches for optimizing queries in data integration use decoupled strategies–attempting to optimize coverage and cost in two separate phases. Since sources tend to ha...

Control of an Extensible Query Optimizer: A Planning-Based Approach
III this paper we address the problem of controlling the execution of a query optimizer. We describe a control for the optimization process that is based on planning. The controll...

Detection of Multiple Deformable Objects using PCA-SIFT
In this paper, we address the problem of identifying and localizing multiple instances of highly deformable objects in real-time video data. We present an approach which uses PCA-...

Attribute Grammars for Scalable Query Processing on XML Streams
We introduce the new notion of XML Stream Attribute Grammars (XSAGs). XSAGs are the first scalable query language for XML streams (running strictly in linear time with bounded mem...

Small PCPs with Low Query Complexity
Most known constructions of probabilistically checkable proofs (PCPs) either blow up the proof size by a large polynomial, or have a high (though constant) query complexity. In thi...
