Dynamic feature selection

WebIn this paper, we propose a new dynamic feature selection technique using data clustering algorithms to select features in a dynamic way and the selected features will be used in classification methods. Our technique aims to select the best attributes for a group of instances rather than to the entire dataset, leading to a dynamic way to select ... WebFigure 1: Dynamic feature selection for dependency parsing. (a) Start with all possible edges except those filtered by the length dictionary. (b) – (e) Add the next group of feature templates and parse using the non-projective parser. Predicted trees are shown as blue and red edges, where red indicates the edges that we then decide to lock ...

Weblearning and inference procedures for feature-templated classifiers that optimize both accuracy and inference speed, using a process of dynamic feature selection. Since … WebWe represent the dynamic feature selection process as a Markov Decision Process (MDP). We allow the agent to select more than one feature at a time. A selectable bundle of one or more features is called a factor; such a bundle might be de ned by a feature template, for example, or by a procedure that acquires several fea-tures at once.

WebHowever, existing feature selection algorithms in GP focus more emphasis on obtaining more compact rules with fewer features than on improving effectiveness. This paper is an attempt at combining a novel GP method, GP via dynamic diversity management, with feature selection to design effective and interpretable dispatching rules for DJSS. WebAbstract. We study the problem of feature selection in text classification. Previous researches use only a measurement such as information gain, mutual information, chi-square for selecting good features. In this paper we propose a new approach to feature selection - dynamic feature selection. A new algorithm for feature selection is proposed.

WebA novel algorithm called DyFAV (Dynamic Feature Selection and Voting) is proposed for this purpose that exploits the fact that fingerspelling has a finite corpus (26 letters for ASL). The system uses an independent multiple agent voting approach to identify letters with high accuracy. The independent voting of the agents ensures that the ...
