Semi-supervised learning combining co-training with active learning

作者:

Highlights:

• Our semi-supervised algorithm combines the benefits of both co-training and active learning.

• The most reliable instances are selected according to high confidence and nearest neighbor.

• We define contribution degree as the selection criteria of informative instances.

• Our algorithm achieves significant improvement for sacrificing same amount of human effort.

• Compared with standard co-training, our algorithm worked well on small labeled training sets.
