Improved multiclass feature selection via list combination

Javier Izetta, Pablo F. Verdes, Pablo M. Granitto
2017 Expert systems with applications  
When using SVM-RFE on a multiclass classification problem, the usual strategy is to decompose it into a series of binary ones, and to generate an importance statistics for each feature on each binary problem  ...  These importances are then averaged over the set of binary problems to synthesize a single value for feature ranking. In some cases, however, this procedure can lead to poor selection.  ...  In both cases, we created the corresponding binary problems and 248 produced a ranking of features for each of them.  ...

Takeover prediction using forecast combinations

Bruno Dore Rodrigues, Maxwell J. Stevenson
2013 International Journal of Forecasting  
Forecasts from several non-linear forecasting models, such as logistic and neural network models and a combination of them, are used to explore the methodology that better reduces the out-of-sample misclassification  ...  First, the forecast combination method outperforms that of the single models and should be used to improve the prediction accuracy of takeover targets.  ...  Nonetheless, the combination of probability forecasts of a binary variable defined on the [0, 1] interval appeared later when Kamstra and Kennedy (1998) introduced a method to combine log-odds ratios  ...

Ontology Employment in Text Document Clustering combined with Grouping Algorithm

Hmway HmwayTar, Pye Phyo Oo
2013 International Journal of Applied Information Systems  
For the experiments the system has to use ontology that enables us to describe and organize this from heterogeneous sources, and to cluster about it.  ...  Moreover, there are many of computer science and medical based subject related papers and journals cited on the Internet.  ...  But this method only considers the times which the words appear, while ignoring other factors which may impact the word weighs. And also this method is only a binary weighting method.  ...
