Active learning and discovery of object categories in the presence of unnameable instances
2015
2015 IEEE Conference on Computer Vision and Pattern Recognition (CVPR)
Preserved Fulltext
To meet these observations, we present a variant of the expected model output change principle for active learning and discovery in the presence of unnameable instances. ...
In active learning, all categories occurring in collected data are usually assumed to be known in advance and experts should be able to label every requested instance. ...
Active learning with unnameable instances Problem setting A very common assumption in active learning is that the oracle (e.g., a human annotator) can provide a label for every instance of the set of unlabeled ...

The system takes object/scene-labeled images as input, and returns as output a set of attributes elicited from human annotators that distinguish the categories of interest. ...
To ensure a compact vocabulary and efficient use of annotators' effort, we 1) show how to actively augment the vocabulary such that new attributes resolve inter-class confusions, and 2) propose a novel ...
