Sparse Linear Discriminant Analysis using the Prior-Knowledge-Guided Block Covariance Matrix

There are two key challenges when using a linear discriminant analysis in the high-dimensional setting, including singularity of the covariance matrix and difficulty of interpreting the resulting classifier. Although several methods have been proposed to address these problems, they focused only on...
