Composite Logconcave Sampling with a Restricted Gaussian Oracle [article]

Ruoqi Shen, Kevin Tian, Yin Tat Lee
2020 arXiv   pre-print
We consider sampling from composite densities on $\mathbb{R}^d$ of the form $d\pi(x) \propto \exp(-f(x) - g(x))dx$ for well-conditioned $f$ and convex (but possibly non-smooth) $g$, a family generalizing  ...  restrictions to a convex set, through the abstraction of a restricted Gaussian oracle.  ...  Acknowledgments We thank Yair Carmon for suggesting the experiment in Section 4.  ...

Guaranteed Validity for Empirical Approaches to Adaptive Data Analysis [article]

Ryan Rogers, Aaron Roth, Adam Smith, Nathan Srebro, Om Thakkar, Blake Woodworth
2020 arXiv   pre-print
When paired with good heuristics, this method gives guarantees that are orders of magnitude better than the best worst-case bounds. We provide a Python library implementing our method.  ...  We design a general framework for answering adaptive statistical queries that focuses on providing explicit confidence intervals along with point estimates.  ...  ., and O.T. were visiting the Simons Institute for the Theory of Computing.  ...
