Multivariate Stein Factors for a Class of Strongly Log-concave Distributions
Lester Mackey, Jackson Gorham
We establish uniform bounds on the low-order derivatives of Stein equation solutions for a broad class of multivariate, strongly log-concave target distributions. These "Stein fact…
Jet-Images -- Deep Learning Edition
Luke de Oliveira, Michael Kagan, Lester Mackey +2
Building on the notion of a particle physics detector as a camera and the collimated streams of high energy particles, or jets, it measures as an image, we investigate the potentia…
Fuzzy Jets
Lester Mackey, Benjamin Nachman, Ariel Schwartzman +1
Collimated streams of particles produced in high energy physics experiments are organized using clustering algorithms to form jets. To construct jets, the experimental collaboratio…
Empirical Bayesian analysis of simultaneous changepoints in multiple data sequences
Zhou Fan, Lester Mackey
Copy number variations in cancer cells and volatility fluctuations in stock prices are commonly manifested as changepoints occurring at the same positions across related data seque…
Measuring Sample Quality with Stein's Method
Jackson Gorham, Lester Mackey
To improve the efficiency of Monte Carlo estimation, practitioners are turning to biased Markov chain Monte Carlo procedures that trade off asymptotic exactness for computational s…
