Nonparametric Adaptive Robust Control under Model Uncertainty
SIAM Journal on Control and Optimization, 2023 We consider a discrete time stochastic Markovian control problem under model uncertainty. Such uncertainty not only comes from the fact that the true probability law of the underlying stochastic process is unknown, but the parametric family of probability distributions which the true law belongs to is also unknown.

Counterfactual Sensitivity and Robustness [PDF]
Econometrica, 2019 We propose a framework for analyzing the sensitivity of counterfactuals to parametric assumptions about the distribution of latent variables in structural models.

Psych, 2023 In psychological research, comparisons between two groups are frequently made to demonstrate that one group exhibits higher values. Although Welch’s unequal variances t-test has become the preferred parametric test for this purpose, surpassing Student’s ...

Using a bootstrap approach to rate the raters [PDF]
, 2004 This paper compares the accuracy of credit ratings of Moody s and Standard&Poors. Based on 11,428 issuer ratings and 350 defaults in several datasets from 1999 to 2003 a slight advantage for the rating system of Moody s is detected.

On the Effect of Bias Estimation on Coverage Accuracy in Nonparametric Inference [PDF]
Journal of the American Statistical Association, 2015 Nonparametric methods play a central role in modern empirical work. While they provide inference procedures that are more robust to parametric misspecification bias, they may be quite sensitive to tuning parameter choices.

Local kernel nonparametric discriminant analysis for adaptive extraction of complex structures
Open Physics, 2017 The linear discriminant analysis (LDA) is one of popular means for linear feature extraction. It usually performs well when the global data structure is consistent with the local data structure.

Efficient Global Point Cloud Alignment Using Bayesian Nonparametric Mixtures [PDF]
Computer Vision and Pattern Recognition, 2016 Point cloud alignment is a common problem in computer vision and robotics, with applications ranging from 3D object recognition to reconstruction. We propose a novel approach to the alignment problem that utilizes Bayesian nonparametrics to describe the ...
