详细描述

The class TOPFeatures implements TOP kernel features obtained from two Hidden Markov models.

It was used in

K. Tsuda, M. Kawanabe, G. Raetsch, S. Sonnenburg, and K.R. Mueller. A new discriminative kernel from probabilistic models. Neural Computation, 14:2397-2414, 2002.

which also has the details.

Note that TOP-features are computed on the fly, so to be effective feature caching should be enabled.

It inherits its functionality from CSimpleFeatures, which should be consulted for further reference.

在文件TOPFeatures.h第68行定义。
