The checkerboard copula and dependence concepts
Liyuan Lin, Ruodu Wang, Ruixun Zhang +1
We study the problem of choosing the copula when the marginal distributions of a random vector are not all continuous. Inspired by four motivating examples including simulation fro…
On Consistency of Signature Using Lasso
Xin Guo, Binnan Wang, Ruixun Zhang +1
Signatures are iterated path integrals of continuous and discrete-time processes, and their universal nonlinearity linearizes the problem of feature selection in time series data a…
The Success of AdaBoost and Its Application in Portfolio Management
Yijian Chuan, Chaoyi Zhao, Zhenrui He +1
We develop a novel approach to explain why AdaBoost is a successful classifier. By introducing a measure of the influence of the noise points (ION) in the training data for the bin…
Deep Dexterous Grasping of Novel Objects from a Single View
Umit Rusen Aktas, Chao Zhao, Marek Kopicki +2
Dexterous grasping of a novel object given a single view is an open problem. This paper makes several contributions to its solution. First, we present a simulator for generating an…
