Clustering with instance-level constraints
Webconstraints and in the presentation of an active constraint selection strategy. 2. Instance vs. Space Level Constraints While it is important for a clustering algorithm to satisfy known constraints, it is equally important for the algorithm to satisfy the implications of those constraints. For exam- WebInstance and Cluster Level Constraints∗ Ian Davidson† S. S. Ravi‡ Abstract Recent work has looked at extending clustering algorithms with instance level must-link (ML) and cannot-link (CL) background information. Our work introduces δ and ǫ cluster level constraints that influence inter-cluster distances and cluster composition.

WebTo our knowledge, only a limited amount of work exists in the application of instance-level constraints to hierarchical clustering [16, 8]. The addition of constraints to non-hierarchical cluster-ing has produced many benefits [4] and we believe that the addition of constraints to hierarchical clustering algorithms will also yield similar ... WebAbstract Recent work has looked at extending the k-Means algorithm to incorporate background information in the form of instance level must-link and cannot-link constraints. We introduce two ways of specifying additional background information in the form of δ and ∊ constraints that operate on all instances but which can be interpreted as conjunctions …
WebDec 31, 2004 · Different application areas of semi-supervised clustering with constraints have been studied recently, including (1) image segmentation for object identification in Aibo robots ( Davidson and Ravi 2005a ), where cluster-level constraints are used to improve the pixel clustering; (2) object recognition in video sequences (Yan et al. 2004), where …
