WG-IDENT: Weak Group Identification of PDEs with Varying Coefficients
Cheng Tang, Roy Y. He, Hao Liu
The identification of Partial Differential Equations (PDEs) has emerged as a prominent data-driven approach for mathematical modeling and has attracted considerable attention in re…
On the tightness of linear relaxation based robustness certification methods
Cheng Tang
There has been a rapid development and interest in adversarial training and defenses in the machine learning community in the recent years. One line of research focuses on improvin…
Exponentially convergent stochastic k-PCA without variance reduction
Cheng Tang
We present Matrix Krasulina, an algorithm for online k-PCA, by generalizing the classic Krasulina's method (Krasulina, 1969) from vector to matrix case. We show, both theoretically…
Convergence rate of stochastic k-means
Cheng Tang, Claire Monteleoni
We analyze online \cite{BottouBengio} and mini-batch \cite{Sculley} -means variants. Both scale up the widely used -means algorithm via stochastic approximation, and have bec…
Convergence rate of stochastic k-means
Cheng Tang, Claire Monteleoni
We analyze online and mini-batch k-means variants. Both scale up the widely used Lloyd 's algorithm via stochastic approximation, and have become popular for large-scale clustering…
