A Double Parametric Bootstrap Test for Topic Models
Skyler Seto, Sarah Tan, Giles Hooker +1
Non-negative matrix factorization (NMF) is a technique for finding latent representations of data. The method has been applied to corpora to construct topic models. However, NMF ha…
Statistical Inference on Tree Swallow Migrations with Random Forests
Tim Coleman, Lucas Mentch, Daniel Fink +4
Bird species' migratory patterns have typically been studied through individual observations and historical records. In recent years however, the eBird citizen science project, whi…
Distill-and-Compare: Auditing Black-Box Models Using Transparent Model Distillation
Sarah Tan, Rich Caruana, Giles Hooker +1
Black-box risk scoring models permeate our lives, yet are typically proprietary or opaque. We propose Distill-and-Compare, a model distillation and comparison approach to audit suc…
Timing Observations of Diffusions
Aurya Javeed, Giles Hooker
This paper addresses a problem in experimental design: We consider Itô diffusions specified by some and assume that we are allowed to observe their sample paths o…
Sparse Inverse Covariance Estimation for High-throughput microRNA Sequencing Data in the Poisson Log-Normal Graphical Model
David Sinclair, Giles Hooker
We introduce the Poisson Log-Normal Graphical Model for count data, and present a normality transformation for data arising from this distribution. The model and transformation are…
An Expectation Maximization Algorithm for High-Dimensional Model Selection for the Ising Model with Misclassified States
David G. Sinclair, Giles Hooker
We propose the misclassified Ising Model; a framework for analyzing dependent binary data where the binary state is susceptible to error. We extend the theoretical results of the m…
