High Dimensional Quadratic Discriminant Analysis: Optimality and Phase Transitions

Wanjie Wang, Jingjing Wu, Zhigang Yao

Consider a two-class classification problem where we observe samples $(X_{i}, Y_{i})$ for i = 1, ..., n, $X_{i} \in R^{p}$ and $Y_{i}$ in {0, 1}. Given $Y_{i} = k$ , $X_{i}$ is assumed to follow…

Sufficient Dimension Reduction for Classification

Xin Chen, Jingjing Wu, Zhigang Yao +1

We propose a new sufficient dimension reduction approach designed deliberately for high-dimensional classification. This novel method is named maximal mean variance (MMV), inspired…
