SUPPORT VECTOR MACHINES FOR PATTERN CLASSIFICATION PPT

To sum up, the limitations of much related work extracting novel features are that they only focuses on sol- ving some specific domain problem. In addition, they use their proposed features to directly compare with original features in terms of classification accuracy and/or errors, i. e., th[r]

In many applications in the field of audio signal process- ing, the specific signal model is unknown and the spectral charasteristics may be quite varied. This is typical especially within the field of animal and natural sounds. In these ap- plications it is common to u[r]

In this paper, we study the impact of the financial crisis while integrating DEA efficiency measures with Support Vector Machines (SVM). Moreover, to account for the heterogeneity effect in the efficiency measures, the gap statistical method of Tibshirani, et al., (2001) [Tibshirani, R., Walther, G.[r]

We have just established that the feature ranking coefficients can be used as classifier weights. Reciprocally, the weights multiplying the inputs of a given classifier can be used as feature ranking coefficients. The inputs that are weighted by the largest value influence most the classification[r]

1. Introduction
A robot is said to be fully autonomous if it is able to build a navigation map. The map is a representation of a robot surroundings modelled as 2D geometric features extracted from a proximity sensor like laser. It provides succinct space descript[r]
