Abstract Attribute Exploration with Partial Object Descriptions

چکیده

Attribute exploration has been investigated in several studies, with particular emphasis on the algorithmic aspects of this knowledge acquisition method. In its basic version the method itself is rather simple and transparent. But when background knowledge and partially described counterexamples are admitted, it gets more difficult. Here we discuss this case in an abstract, somewhat “axiomatic” setting, providing a terminology that clarifies the abstract strategy of the method rather than its algorithmic implementation.

Interactive Multi-object Segmentation with Max-tree Filtering

This thesis presents a novel multi-object segmentation approach for volumetric grayscale data that separates the segmentation process into an unattended preprocessing phase and an interactive exploration phase. The first produces a set of feature candidates, which the user then filters repeatedly until only the desired features remain. The interactive, visualization-driven exploration completel...

Obtaining Trees from Their Descriptions :

2 The authors are indebted to the referees for considerable help in clarifying the presentation of this material. Abstract Partial descriptions are sets of constraints which do not necessarily determine a unique object. Two related issues arise when objects are speciied by partial descriptions. The rst asks whether a given description is satissed by any object. The second seeks to produce, from...

  As an ontologist philosopher Shaykh al – Isharq believes in a heirarchegal being on the basis of which presents his classification of various descriptions. These descriptions are various both in terms of longitudinal and latitudinal. That is, for instance though his intative descriptions are at the latitude of his logical analytic descriptions, possesses itself a longitudinal order successiv...

Constructing Abstract Maps from Spatial Descriptions for Goal-directed Exploration

This paper describes ongoing work on a system using spatial descriptions to construct abstract maps that can be used for goal-directed exploration in an unfamiliar office environment. Abstract maps contain membership, connectivity, and spatial layout information extracted from symbolic spatial information. In goal-directed exploration, the robot would then link this information with observed sy...

Building Classes in Object-Based Languages by Automatic Clustering

The paper deals with clustering of objects described both by properties and relations. Relational attributes may make object descriptions recursively depend on themselves so that attribute values cannot be compared before objects themselves are. An approach to clustering is presented whose core element is an object dissimilarity measure. All sorts of object attributes are compared in a uniform ...
