Interactive Knowledge Frontier Discovery with COBWEB-KFD
نویسندگان
چکیده
Knowledge frontier discovery is a novel technique for identifying interesting subpopulations of a dataset with respect to classification performance. A knowledge frontier is a collection of meaningful groups where any sub-partition with significantly different predictive accuracy is not meaningful. This research introduces knowledge frontiers and knowledge frontier discovery. The first knowledge frontier discovery algorithm, COBWEB-KFD, is also described in detail. Knowledge frontier discovery extends clustering and subgroup discovery to provide information that those techniques cannot.

The Arts in Psychotherapy A Computer Art Therapy System for Kinetic Family Drawing (CATS KFD)
This study delineates the development of the Computer Art Therapy System for the Kinetic Family Drawing (CATS KFD) which uses given patterns instead of free drawings. The CATS KFD consists of four stages. The system provides clients with questionnaires on their family relationships and color preferences, and their answers constitute a fact base. The system provides the client with various patte...
متن کاملCobweb: a Java applet for network exploration and visualisation
SUMMARY Cobweb is a Java applet for real-time network visualization; its strength lies in enabling the interactive exploration of networks. Therefore, it allows new nodes to be interactively added to a network by querying a database on a server. The network constantly rearranges to provide the most meaningful topological view. AVAILABILITY Cobweb is available under the GPLv3 and may be freely...
متن کاملKnowledge Discovery from Client-Server Databases
The subject of this paper is the implementation of knowledge discovery in databases. Speciically, we assess the requirements for interfacing tools to client-server database systems in view of the architecture of those systems and of \knowledge discovery processes". We introduce the concept of a query frontier of an exploratory process, and propose a strategy based on optimizing the current quer...

متن کاملGraph-Based Hierarchical Conceptual Clustering
Hierarchical conceptual clustering has proven to be a useful, although under-explored, data mining technique. A graph-based representation of structural information combined with a substructure discovery technique has been shown to be successful in knowledge discovery. The SUBDUE substructure discovery system provides one such combination of approaches. This work presents SUBDUE and the develop...
