This paper introduces the problem of Private Linear Transformation (PLT) which generalizes problems private information retrieval and linear computation. The PLT includes one or more remote server(s) storing (identical copies of) $K$ ...

We propose a new algorithm called Generalized Discriminative Feature Transformation (GDFT) for acoustic models in speech recognition. GDFT is based on Lagrange relaxation on a transformed optimization problem. We show that the existing discriminative feature transformation methods like feature space MMI/MPE (fMMI/MPE), region dependent linear transformation (RDLT), and a non-discriminative feat...
