Inference Principles and Model Selection
The core problem of statistics and machine learning addresses the question how can we efficiently find a statistical model to describe empirical data. Classical statistical approaches to solve this problem have been complemented during the last 15 years by Neural Computation, a very promising strategy to data analysis. The Dagstuhl seminar on “Inference Principles and Model Selection” — the fourth in a series of Machine Learning and Neural Computation workshops in 1994, 1997, 1999 and 2001 — was intended to review this exciting development of the field and to discuss the foundation of statistical and computational learning theory with its deep (and still unresolved) questions. The participants represented all of the involved disciplines from statistics and computer science to information theory and philosophy. The burning question of many participants if there exist notions of inference studied in philosophy that machine learning has overlooked so far came up in several sessions and especially in the first tutorial on Philosophical Foundations (Matthias Hild). Three pioneers of the field, Sun-ichi Amari, Phil Dawid and Vladimir Vapnik provided valuable insights how the field of learning machines developed from the sixties up to today and what kind of challenges are lying still ahead of us.
