Posterior probability support vector Machines for ...

    https://ieeexplore.ieee.org/document/1528532/
    Abstract: This paper proposes a complete framework of posterior probability support vector machines (PPSVMs) for weighted training samples using modified concepts of risks, linear separability, margin, and optimal hyperplane. Within this framework, a new optimization problem for unbalanced classification problems is formulated and a new concept of support vectors established.Cited by: 132
