Semi-supervised learning through adaptive Laplacian graph trimming

作者:

Highlights:

• A method which can adaptively fit a proper Laplacian weighted graph from data.

• A penalty helping cut inter-cluster shortcuts and enhance intra-cluster connections.

• A graph-based SSL model is less sensitive to neighborhood size by integrating ALGT.

• Superiority of ALGT is verified by experimental results on synthetic and UCI data.
