%description
We connect the multi-class Neyman-Pearson classification (NP) problem to
the cost-sensitive learning (CS) problem, and propose two algorithms
(NPMC-CX and NPMC-ER) to solve the multi-class NP problem through
cost-sensitive learning tools. Under certain conditions, the two
algorithms are shown to satisfy multi-class NP properties. More details
are available in the paper "Neyman-Pearson Multi-class Classification via
Cost-sensitive Learning" (Ye Tian and Yang Feng, 2021).
