    Linear Projection based on Noise Variance Estimation - Application to Spectral Data
    Download  www.dice.ucl.ac.be
    In this paper, we propose a new methodology to build latent variables that are optimal if a nonlinear model is used afterward. This method is based on Nonparametric Noise Estimatio...
