A Fast Algorithm for Sparse Nonlinear Component Analysis by Sublinear and Spectral Changes


A Fast Algorithm for Sparse Nonlinear Component Analysis by Sublinear and Spectral Changes – In this paper, we propose a Bayesian method for learning a non-Gaussian vector to efficiently update the posterior of multiple unknown variables. We formulate the process of learning a non-Gaussian vector as a matrix multiplication problem, and define the covariance matrix that is to be transformed to the covariance matrix in the prior for each data point. We derive a generalization error bound for matrix multiplication under non-Gaussian conditions for each unknown parameter. Our method is a hybrid of these two approaches.

Feature selection is crucial for image classification. Existing work has focused on image segmentation by using linear discriminant analysis or segmentation by multiple images. Here we propose a novel approach that uses the discriminant equation to form a segmentation problem. Specifically, the discriminant equation (DIA) is formulated as a multi-class objective function, and we show that the discriminant equation is more tractable to learn. We also show that a simple iterative approach to the formulation can be used for classifying the data in a deep architecture. Experiments show the proposed approach significantly outperforms the existing approaches.
