Sequential Fixed-Point ICA Based on Mutual Information Minimization
A new gradient technique is introduced for linear independent component analysis (ICA) based on the Edgeworth expansion of mutual information, for which the algorithm operates sequentially using fixed-point iterations. In order to address the adverse effect of outliers, a robust version of the Edgeworth expansion is adopted, in terms of robust cumulants, and robust derivatives of the Hermite po...
متن کاملInput Feature Selection by Mutual Information Based on Parzen Window
Mutual information is a good indicator of relevance between variables, and have been used as a measure in several feature selection algorithms. However, calculating the mutual information is difficult, and the performance of a feature selection algorithm depends on the accuracy of the mutual information. In this paper, we propose a new method of calculating mutual information between input and ...
متن کاملMutual Information Based Input Variable Selection Algorithm and Wavelet Neural Network for Time Series Prediction
In this paper we have presented an IntegratedWavelet Neural Network (WNN) model and Mutual Information (MI)-based input selection algorithm for time series prediction. Based on MI the proper input variables, which describe the time series’ dynamics properly, will be selected. The WNN Prediction model uses selected variables and predicts the future. This model utilized for time series prediction...
متن کاملAdaptive motion estimation schemes using maximum mutual information criterion
We consider the motion estimation problem in video coding. In our previous work [10], we proposed a new motion estimation method where motion estimation is formulated as an optimization problem and an adaptive system under the minimum error entropy criterion is used for motion estimation. In this paper, we develop an adaptive system under the criterion of maximum mutual information to address t...
