摘要:
for a multicategory classification problem, discriminative least squares regression (dlsr) explicitly introduces an ϵ-dragging technique to enlarge the margin between the categories, yielding superior classification performance from a margin perspective. in this brief, we reconsider this classification problem from a metric learning perspective and propose a framework of metric learning-guided least squares classifier (mlg-lsc) learning. the core idea is to learn a unified metric matrix for the error of lsr, such that such a metric matrix can yield small distances for the same category, while large ones for the different categories. as opposed to the ϵ-dragging in dlsr, we call this the error-dragging (e-dragging). different from dlsr and its related variants, our mlg-lsc implicitly carries out the e-dragging and can naturally reflect the roughly relative distance relationships among the categories from a metric learning perspective. furthermore, our optimization objective functions are strictly (geodesically) convex and thus can obtain their corresponding closed-form solutions, resulting in higher computational performance. experimental results on a set of benchmark data sets indicate the validity of our learning framework. © 2012 ieee.
