Automatic Database Creation and Object's Model Learning

This paper proposes a new framework to automatically generate visual object database meanwhile efficiently learn the object’s model. The system is of important need for the problems of object detection and recognition. Our main idea is to acquire the huge amount of video data actively, and seeks out opportunities to autonomously exploit information from object samples. We employ autonomous lear...

Tree-structured object creation in database transformations

Within the class of “determinate” object-creating database transformations, identified by Abiteboul and Kanellakis, a natural proper subclass consists of the so-called “constructive” transformations. A determinate transformation is constructive if its input-output pairs satisfy a condition discovered by Jan Paredaens. In this note we point out that when object creation is “tree-structured,” as ...

Automated Creation of Pattern Database Search Heuristics

Pattern databases are dictionaries for heuristic estimates storing state-to-goal distances in state space abstractions. Their effectiveness is sensitive to the selection of the underlying patterns. Especially for multiple and additive pattern databases, the manual selection of patterns that leads to good exploration results is involved. For automating the selection process, greedy bin-packing h...

Fear and Desire in Database Creation

Organizations need quality information for control and coordination of their operations. Yet, despite the resources expended on data production, data often proves to be unreliable or inadequate when used in practice. To understand this puzzle, I conducted an ethnographic study of the production of a database system within one organization. Database systems provide the scaffolding to hold the da...
