Meeting of the British Classification Society
‘Academic obsessions and classification realities:
ignoring practicalities in supervised classification’
by
Professor David Hand (Imperial College)
(President-elect, International Federation of Classification Societies)
Abstract: Supervised classification methods have been the focus of a vast
amount of research in recent decades, within a variety of intellectual
disciplines, including statistics, machine learning, pattern recognition, and data
mining. However, most of the advances have largely taken place within the
context of the classical supervised classification paradigm of data analysis.
That is, a classification rule is constructed based on a given 'design sample' of
data, with known and well-defined classes, and this rule is then used to classify
future objects. This talk argues that this paradigm is often, perhaps typically,
an over- idealisation of the practical realities of supervised classification
problems, leading to the suspicion that the apparent superiority of the highly
sophisticated methods is often illusory: simple methods are often equally
effective or even superior in classifying new data points.
