Reinterpreting No Free Lunch
Abstract Since its inception, the "No Free Lunch" theorem (NFL) has concerned the application of symmetry results rather than the symmetries themselves. In our view, the conflation of result and application obscures the simplicity, generality, and power of the symmetries involved. This paper separates result from application, focusing on and clarifying the nature of underlying symmetries. The r...
متن کاملNo Free Lunch
Some philosophers (see (Armstrong, 1997), (Cameron, 2008), (Melia, 2005), and (Schaffer, 2007, 2009, 2010a)) have recently suggested that explanations of a certain sort can mitigate our ontological commitments. The explanations in question, grounding explanations, are those that tell us what it is in virtue of which an entity exists and has the features it does. These philosophers claim that th...
متن کاملNo-Free-Lunch theorems in the continuum
No-Free-Lunch Theorems state, roughly speaking, that the performance of all search algorithms is the same when averaged over all possible objective functions. This fact was precisely formulated for the first time in a now famous paper by Wolpert and Macready, and then subsequently refined and extended by several authors, always in the context of a set of functions with discrete domain and codom...
متن کاملNo-Free-Lunch and Bayesian Optimality
We take a Bayesian approach to the issues of bias, meta bias, transfer, overfit, and No-Free-Lunch in the context of supervised learning. If we accept certain relationships between the function class, on training set data, and off training set data, then a graphical model can be created that represents the supervised learning problem. This graphical model dictates a specific algorithm which wil...
متن کاملNo Free Lunch with the Sandwich
In nonlinear regression theory, the sandwich estimator of the covariance matrix of the model parameters is known as a consistent estimator, even when the parameterized model does not contain the regression. However, in the latter case, we emphasize the fact that the consistency of the sandwich holds only if the inputs of the training set are the values of independent identically distributed ran...
