Cross-Validation Optimization for Large Scale Structured Classification Kernel Methods
... Test errors are 4.77%(±0.18%). These results are state-of-the-art for kernel classification. Seeger (2003) reports 4.98% for the IVM (Sect. 4.8.4), where hyperparameters are learned auto- matically. Csat ´o (2002) states ...
