WebA Bayesian model of learning to learn by sampling from multiple tasks is presented. The multiple tasks are themselves generated by sampling from a distribution over an environment of related tasks. Such an environment is shown to be naturally modelled within a Bayesian context by the concept of an objective prior distribution. It is argued that for … WebHierarchical sampling for active learning. In Proceedings of the 25th International Conference on Machine Learning (ICML’08). 208--215. Google Scholar Digital Library; S.

Our method relies on hierarchical clustering. Unlike tra-ditional active learning methods, our method is unsupervised and the selected training sets can be used to train di‡erent learning to rank models. ct hb 5269
