Multi-Tuple Deletion Propagation: Approximations and Complexity
This paper studies the computational complexity of the classic problem of deletion propagation in a relational database, where tuples are deleted from the base relations in order to realize a desired deletion of tuples from the view. Such an operation may result in a (sometimes unavoidable) side effect: deletion of additional tuples from the view, besides the intentionally deleted ones. The goa...
متن کاملEfficient Multi-relational Classification by Tuple ID Propagation
Most of today’s structured data is stored in relational databases. In contrast, most classification approaches only apply on single “flat” data relations. And it is usually difficult to convert multiple relations into a single flat relation without losing essential information. Inductive Logic Programming approaches have proven effective with high accuracy in multi-relational classification. Un...
متن کاملN-tuple Color Segmentation for Multi-view Silhouette Extraction
We present a new method to extract multiple segmentations of an object viewed by multiple cameras, given only the camera calibration. We introduce the n-tuple color model to express inter-view consistency when inferring in each view the foreground and background color models permitting the final segmentation. A color n-tuple is a set of pixel colors associated to the n projections of a 3D point...

متن کاملA Hybrid Multi-attribute Group Decision Making Method Based on Grey Linguistic 2-tuple
Because of the complexity of decision-making environment, the uncertainty of fuzziness and the uncertainty of grey maybe coexist in the problems of multi-attribute group decision making. In this paper, we study the problems of multi-attribute group decision making with hybrid grey attribute data (the precise values, interval numbers and linguistic fuzzy variables coexist, and each attribute val...
