Phys. Rev. Lett. 89, 108302 (2002) [4 pages]Statistical Mechanics of Learning: A Variational Approach for Real DataReceived 10 January 2002; published 19 August 2002 Using a variational technique, we generalize the statistical physics approach of learning from random examples to make it applicable to real data. We demonstrate the validity and relevance of our method by computing approximate estimators for generalization errors that are based on training data alone. © 2002 The American Physical Society URL:
