Sentiment classification is the task of labeling a review document according to the polarity of its prevailing opinion (favorable or unfavorable). In approaching this problem, a model builder often ha...
Margin trees for high-dimensional classification
Maximum margin classifier supprt vector machine decision tree CART
font style='font-size:12px;'>
2015/8/21
We propose a method for the classification of more than two classes, from high-dimensional features. Our approach is to build a binary decision tree in a top-down manner, using the optimal margin clas...
Classification of Spatio - Temporal Pattern of Rainfall in Iran Using a Hierarchical and Divisive Cluster Analysis
Rainfall pattern Cluster Analysis Ward Method Iran

2015/8/11
The identification of spatial rainfall pattern is an essential task for hydrologists, climatologists as well as regional and local planners and managers. This is due to the variability of both the tem...
Pareto optimal linear classification
Linear classifier probability weigh gaussian distribution
