An Inter-Domain Supervision Framework For Collaborative Clustering Of Data With Mixed Types., Artur Abdullin Dec 2013

An Inter-Domain Supervision Framework For Collaborative Clustering Of Data With Mixed Types., Artur Abdullin

Electronic Theses and Dissertations

We propose an Inter-Domain Supervision (IDS) clustering framework to discover clusters within diverse data formats, mixed-type attributes and different sources of data. This approach can be used for combined clustering of diverse representations of the data, in particular where data comes from different sources, some of which may be unreliable or uncertain, or for exploiting optional external concept set labels to guide the clustering of the main data set in its original domain. We additionally take into account possible incompatibilities in the data via an automated inter-domain compatibility analysis. Our results in clustering real data sets with mixed numerical, categorical ...


Collaborative Context-Based Reasoning, Gilbert Barrett Jan 2007

Collaborative Context-Based Reasoning, Gilbert Barrett

Electronic Theses and Dissertations

This dissertation explores modeling collaborative behavior, based on Joint Intentions Theory (JIT), in Context-Based Reasoning (CxBR). Context-Based Reasoning is one of several contextual reasoning paradigms. And, Joint Intentions Theory is the definitive semantic framework for collaborative behaviors. In order to formalize collaborative behaviors in CxBR based on JIT, CxBR is first described in terms of the more popular Belief, Desire, and Intention (BDI) model. Once this description is established JIT is used as a basis for the formalism for collaborative behavior in CxBR. The hypothesis of this dissertation is that this formalism allows for effective collaborative behaviors in CxBR. Additionally ...
