Active Learning from Crowds
Obtaining labels can be expensive or timeconsuming, but unlabeled data is often abundant and easier to obtain. Most learning tasks can be made more efficient, in terms of labeling cost, by intelligently choosing specific unlabeled instances to be labeled by an oracle. The general problem of optimally choosing these instances is known as active learning. As it is usually set in the context of su...
متن کاملLearning From Crowds
For many supervised learning tasks it may be infeasible (or very expensive) to obtain objective and reliable labels. Instead, we can collect subjective (possibly noisy) labels from multiple experts or annotators. In practice, there is a substantial amount of disagreement among the annotators, and hence it is of great practical interest to address conventional supervised learning problems in thi...
متن کاملDeep learning from crowds
Over the last few years, deep learning has revolutionized the field of machine learning by dramatically improving the state-of-the-art in various domains. However, as the size of supervised artificial neural networks grows, typically so does the need for larger labeled datasets. Recently, crowdsourcing has established itself as an efficient and cost-effective solution for labeling large sets of...

Lane Kenworthy University of Arizona [email protected] administer the “treatment” to some observations. Then we compare the degree of change in both (or all, if there are more than two) groups. With observational data we don’t administer the treatment, but in other respects the process is similar. Especially useful is that this design takes constant countryspecific differences (“country ...

This chapter introduces the Random Modulation Pre-Integrator (RMPI) and details the status of an integrated circuit implementing the architecture. To our knowledge, this is the first full-speed hardware RMPI in existence. The goal of this chapter is to describe some key parameters of the RMPI that are essential to its performance. This is not a hardware chapter and does not go into detail of th...
