Analysis of KNN Density Estimation
Puning Zhao, Lifeng Lai
We analyze the and convergence rates of k nearest neighbor density estimation method. Our analysis includes two different cases depending on whether the supp…
On the Adversarial Robustness of Multivariate Robust Estimation
Erhan Bayraktar, Lifeng Lai
In this paper, we investigate the adversarial robustness of multivariate -Estimators. In the considered model, after observing the whole dataset, an adversary can modify all dat…
Analysis of KNN Information Estimators for Smooth Distributions
Puning Zhao, Lifeng Lai
KSG mutual information estimator, which is based on the distances of each sample to its k-th nearest neighbor, is widely used to estimate mutual information between two continuous…
On Randomized Distributed Coordinate Descent with Quantized Updates
Mostafa El Gamal, Lifeng Lai
In this paper, we study the randomized distributed coordinate descent algorithm with quantized updates. In the literature, the iteration complexity of the randomized distributed co…
