Tree Augmented Naive Bayes Classification (TANC) is not very well to deal with continuous data and it ignores partial data in the absence of data attribute value and this can reduce the result accuracy. To resolve this problem, an improved algorithm based on C4.5 is proposed in this paper. The proposed algorithm firstly modifies the available training data according to the predictions of C4.5, then...
Wind power prediction is of great significance to the safe and stable operation of the power system. The key factor of wind power prediction is the selection of prediction model. This paper chooses support vector machine (SVM) as the wind power prediction model and applies an improved grid search method to optimize the parameters of C and g in SVM model. The model is able to predict the real-time...
A practical system named automatic video thumbnail selection system is proposed for video sharing sites in this paper. It aims to automatically select a best thumbnail among several extracted thumbnails for a video. To achieve this, video thumbnail features including high-level and low-level visual information are proposed and the corresponding scores are calculated firstly. Then a weighting method...
