Robust linear regression through PAC-Bayesian truncation
Linear regression Generalization error Shrinkage
2010/10/14
We consider the problem of predicting as well as the best linear combination of d given functions in least squares regression under $L^\infty$ constraints on the linear combination. When the input dis...

We consider the problem of predicting as well as the best linear combination
of d given functions in least squares regression, and variants of this problem including
constraints on the parameters of...
