Note on free lunches and cross - validationCyril

چکیده
The \no free lunch" theorems (Wolpert and Macready, 1995) have sparked heated debate in the computational learning community. A recent communication, (Zhu and Rohwer, 1996) attempts to demonstrate the ineeciency of cross-validation on a simple problem. We elaborate on this result by considering a broader class of cross-validation. We show that when used more strictly, cross-validation can yield the expected results on simple examples.

متن کاملMultiperiod Security Markets with Differential Information :
We model multiperiod securities markets with differential information. A price system that admits no free lunches is related to martingales when agents have rational expectations.
