To improve the stability of the traditional natural gradient independent component analysis (ICA) algorithm and the accuracy of its separated results, a adaptive step-size natural gradient ICA algorithm with weighted orthogonalization is proposed. First, to take advantage of the pre-whitening pre-processing and keep the equivariance property of the ICA algorithm, based on the weighted orthogonal constraint...
Multi-dimensional Bayesian network classifiers (MBCs) are probabilistic graphical models proposed to solve classification problems. However, in data analysis and preprocessing tasks, one is often confronted with the problem of selecting features from very high dimensional data. To resolve this problem, the covariance analysis and the FastICA algorithm are applied to decrease the dimension and remove...
In this paper, I did much research on the base of the general lightning protection measure. By referring to lots of literature, the author proposed one new lightning protection measure-add horizontal side needle on side of overhead ground wire. This method can has good effect in lightning protection. By theoretical analysis and calculation, we designed a scale model of this new measure. Then we did...
