BookDOI
Semi-Supervised Learning
TL;DR: Semi-supervised learning (SSL) as discussed by the authors is the middle ground between supervised learning (in which all training examples are labeled) and unsupervised training (where no label data are given).
Journal ArticleDOI
Choosing Multiple Parameters for Support Vector Machines
TL;DR: The problem of automatically tuning multiple parameters for pattern recognition Support Vector Machines (SVMs) is considered by minimizing some estimates of the generalization error of SVMs using a gradient descent algorithm over the set of parameters.
Journal ArticleDOI
Support vector machines for histogram-based image classification
TL;DR: It is observed that a simple remapping of the input x(i)-->x(i)(a) improves the performance of linear SVM's to such an extend that it makes them, for this problem, a valid alternative to RBF kernels.
Proceedings Article
An Empirical Evaluation of Thompson Sampling
Olivier Chapelle,Lihong Li +1 more
TL;DR: Empirical results using Thompson sampling on simulated and real data are presented, and it is shown that it is highly competitive and should be part of the standard baselines to compare against.
Proceedings Article
Feature Selection for SVMs
Jason Weston,Sayan Mukherjee,Olivier Chapelle,Massimiliano Pontil,Tomaso Poggio,Vladimir Vapnik +5 more
TL;DR: The resulting algorithms are shown to be superior to some standard feature selection algorithms on both toy data and real-life problems of face recognition, pedestrian detection and analyzing DNA microarray data.
