tree kernel造句

Here are presented two examples of tree kernel applied to the constituency trees of the sentences " A cat eats a mouse . " and " A mouse eats a cat . ".
The interest of these two kernels is that they show very different granularity ( the subset tree kernel being far more fine-grained than the subtree kernel ), for the same computation complexity.
In his studies Collins covers a wide range of topics such as parse re-ranking, tree kernels, semi-supervised learning, machine translation and exponentiated gradient algorithms with a general focus on discriminative models and structured prediction.
