A novel dimensionality reduction method with discriminative generalized eigen-decomposition


Dimensionality reduction plays a critical role in machine learning and computer vision for past decades. In this paper, we propose a discriminative dimensionality reduction method based on generalized eigendecomposition. Firstly, we define the discriminative framework between pairwise classes inspired by the signal to noise ratio. Then the metric is given… (More)
