Picking Groups Instead of Samples: A Close Look at Static Pool-Based Meta-Active Learning

Ignasi Mas, Ramon Morros, Verónica Vilaplana

Abstract: Active Learning techniques are used to tackle learning problems where obtaining training labels is costly. In this work we use Meta-Active Learning to learn to select a subset of samples from a pool of unsupervised input for further annotation. This scenario is called Static Pool-based Meta-Active Learning. We propose to extend existing approaches by performing the selection in a manner that, unlike previous works, can handle the selection of each sample based on the whole selected subset.
