Title: Model-Based Learning for Point Patterns

Abstract:

Stemming from research on handwritten digit recognition in 1990, Multiple instance (MI) learning has emerged as an important topic in Machine Learning. Unlike conventional Machine Learning problems where each datum is a vector, in MI learning each datum is a point pattern or multi-set of unordered points. Despite a host of techniques and applications as well as the fundamental role of statistical models, learning for point pattern data based on statistical models have not yet been investigated. This presentation discusses a framework for model-based point pattern learning using point process theory, which enables principled yet conceptually transparent extensions of learning tasks, such as classification, novelty detection and clustering. Furthermore, tractable point process models as well as solutions for point pattern learning are developed.
