"Have I seen you before? Principles of Bayesian predictive classification Revisited" 

Abstract: 

Classification of objects into a finite set   of alternative classes based 
on observed features of the objects is a common task in statistical 
machine learning. An important application example familiar to most of 
us is spam filtering of email messages. In this talk we review the 
probabilistic basis ! of generative classification and show how a 
particular in! ductive rule of classification arises from basic principles 
of predictive probabilistic modeling pioneered by Seymour Geisser in 
1960's. The standard practice of classifying objects one by one, which 
follows from an i.i.d. assumption, is demonstrated to be at odds with 
laws of predictive probability and we show also that it can be motivated 
as an asymptotic approximation to a more coherent rule. A novel 
inductive principle of predictive classification is introduced and we 
discuss its properties in relation to other principles.

Sincerely, 
Anna Simoni
