Text chunking using regularized Winnow
2001
Proceedings of the 39th Annual Meeting on Association for Computational Linguistics - ACL '01
Preserved Fulltext
Many machine learning methods have recently been applied to natural language processing tasks. ...
Among them, the Winnow algorithm has been argued to be particularly suitable for NLP problems, due to its robustness to irrelevant features. ...
Each kernel support vector machine is computationally significantly more expensive than a corresponding Winnow classifier, and they use an order of magnitude more classifiers. ...
