{"oa_version":"Submitted Version","publisher":"Elsevier","oa":1,"abstract":[{"lang":"eng","text":"In machine learning, the domain adaptation problem arrives when the test (tar-get) and the train (source) data are generated from different distributions.  A key applied issue is thus the design of algorithms able to generalize on a new distribution,  for which we have no label information.  We focus on learning classification models defined as a weighted majority vote over a set of real-valued functions. In this context, Germain et al. (2013) have shown that a measure of disagreement between these functions is crucial to control. The core of this measure is a theoretical bound—the C-bound (Lacasse et al., 2007)—which involves the disagreement and leads to a well performing majority vote learn-ing algorithm in usual non-adaptative supervised setting: MinCq. In this work,we propose a framework to extend MinCq to a domain adaptation scenario.This procedure takes advantage of the recent perturbed variation divergence between distributions proposed by Harel and Mannor (2012).  Justified by a theoretical bound on the target risk of the vote,  we provide to MinCq a tar-get sample labeled thanks to a perturbed variation-based self-labeling focused on the regions where the source and target marginals appear similar.  We also study the influence of our self-labeling, from which we deduce an original process for tuning the hyperparameters. Finally, our framework called PV-MinCq shows very promising results on a rotation and translation synthetic problem."}],"year":"2014","user_id":"4435EBFC-F248-11E8-B48F-1D18A9856A87","type":"journal_article","title":"Domain Adaptation of Weighted Majority Votes via Perturbed Variation-Based Self-Labeling","page":"37-43","citation":{"short":"E.
