Information Laundering for Model Privacy
Xinran Wang, Yu Xiang, Jun Gao +1
In this work, we propose information laundering, a novel framework for enhancing model privacy. Unlike data privacy that concerns the protection of raw data information, model priv…
Estimation of the Evolutionary Spectra with Application to Stationarity Test
Yu Xiang, Jie Ding, Vahid Tarokh
In this work, we propose a new inference procedure for understanding non-stationary processes, under the framework of evolutionary spectra developed by Priestley. Among various fra…
Symmetric Pseudo-Random Matrices
Ilya Soloveychik, Yu Xiang, Vahid Tarokh
We consider the problem of generating symmetric pseudo-random sign (+/-1) matrices based on the similarity of their spectra to Wigner's semicircular law. Using binary m-sequences (…
Pseudo-Wigner Matrices
Ilya Soloveychik, Yu Xiang, Vahid Tarokh
We consider the problem of generating pseudo-random matrices based on the similarity of their spectra to Wigner's semicircular law. We introduce the notion of an r-independent pseu…
Multiple Change Point Analysis: Fast Implementation And Strong Consistency
Jie Ding, Yu Xiang, Lu Shen +1
One of the main challenges in identifying structural changes in stochastic processes is to carry out analysis for time series with dependency structure in a computationally tractab…
