Bootstrap The Original Latent: Learning a Private Model from a Black-box Model

no code implementations7 Mar 2023 Shuai Wang, Daoan Zhang, JianGuo Zhang, Weiwei Zhang, Rui Li

In this paper, considering the balance of data/model privacy of model owners and user needs, we propose a new setting called Back-Propagated Black-Box Adaptation (BPBA) for users to better train their private models via the guidance of the back-propagated results of a Black-box foundation/source model.

Testability-Aware Low Power Controller Design with Evolutionary Learning

Machine Learning of Partial Differential Equations from Noise Data

1 code implementation28 Sep 2020 Wenbo Cao, Weiwei Zhang

Machine learning of partial differential equations from data is a potential breakthrough to solve the lack of physical equations in complex dynamic systems, but because numerical differentiation is ill-posed to noise data, noise has become the biggest obstacle in the application of partial differential equation identification method.
