Rough Notes
Introduces an active learning approach using predictive entropies applied to Gaussian Process (GP) classification (and GP preference learning).
The authors note two approaches to active learning:
- Decision theoretic, (, ), minimizes expected loss after decisions are made based on collected data.
- Information theoretic, (, a), aim to reduce model space as quickly as possible, often using concepts from information theory.
