A Column Generation Bound Minimization Approach with PAC-Bayesian Generalization Guarantees

AISTATS 2016poster

The C-bound, introduced in Lacasse et al (2006), gives a tight upper bound on the risk of the majority vote classifier. Laviolette et al. (2011) designed a learning algorithm named MinCq that outputs a dense distribution on a finite set of base classifiers by minimizing the C-bound, together with a…

PAC-Bayesian Bounds based on the Rényi Divergence

AISTATS 2016poster

We propose a simplified proof process for PAC-Bayesian generalization bounds, that allows to divide the proof in four successive inequalities, easing the "customization" of PAC-Bayesian theorems. We also propose a family of PAC-Bayesian bounds based on the Rényi divergence between the prior and post…
