Semi-Supervised Learning on Data Streams via Temporal Label Propagation

no code implementations • ICML 2018 • Tal Wagner, Sudipto Guha, Shiva Kasiviswanathan, Nina Mishra

We consider the problem of labeling points on a fast-moving data stream when only a small number of labeled examples are available.
