To that end, we introduce first-order Markov chains as a novel model class for exceptional model mining and present a new interestingness measure that quantifies the exceptionality of transition subgroups ...
Although exceptional model mining provides a well-suited framework for our problem, previously investigated model classes cannot capture transition behavior. ...
This classical data mining task aims at finding descriptions of data subsets that show an unusual statistical distribution of a target concept. ...

Subgroup patterns are local findings identifying the subgroups of a population with some unusual, unexpected, or deviating distribution of a target attribute. ...
In this paper, we present a novel subgroup pattern extraction and visualization system, called the Nugget Browser, that takes advantage of both data mining methods and interactive visual exploration. ...
It is clear that without the visualization, analysts cannot understand how the subgroups are distributed in the space and the relationships between the subgroups. ...

This view immediately enables iterative mining of such patterns. Our work generalizes prior work on dense subgraph mining (i.e. subgraphs induced by a single subgroup). ...
The connectivity of a graph can thus possibly be understood in terms of patterns of the form 'the subgroup of individuals with properties X are often (or rarely) friends with individuals in another subgroup ...
