Visualizing the City

Google Streetview now provides an enormously rich picture of the physical streetscapes of the world's cities. Advances in computer recognition techniques make it possible to use images to predict local demographics or the curb appeal of particular places. We show how the combination of Google Streetview and computer vision techniques can map the patterns of neighborhood in six American cities. We also use these methods to predict income in the U.S...

Bias in, bias out: predictive models in the criminal justice system

Predictive models are increasingly used in the criminal justice system to try to predict who will commit crime in the future and where that crime will occur. But what happens when these models are trained using biased data? In this talk, I will present two examples of how biased data is used in the criminal justice system. In the first example, I will introduce a recently published model used for...

The Type Ia Supernova Color­-Magnitude Relation and Host Galaxy Dust: A Simple Hierarchical Bayesian Model

Type Ia supernovae (SN Ia) are faraway exploding stars used as standardizable candles'' to determine cosmological distances, measure the accelerating expansion of the Universe, and constrain the properties of dark energy. Inferring peak luminosities of SN Ia from distance-independent observables, such as the shapes and colors of their light curves (time series), underpins the evidence for cosmic acceleration....

Balancing Covariates via Propensity Score Weighting: The Overlap Weights

Propensity score weighting is often utilized to achieve covariate balance when comparing treatment groups in observational studies. Here we define a general class of balancing weights that balance the weighted covariate distribution between groups. This class includes the commonly used inverse-probability weights, but we illustrate here why these weights can be problematic if covariates...

BET on Independence

We study the problem of model-free dependence detection. This problem can be difficult even when the marginal distributions are known. We explain this difficulty by showing the impossibility to uniformly consistently distinguish degeneracy from independence with any single test. To make model-free dependence detection a tractable problem, we introduce the concept of binary expansion statistics (BEStat) and propose the binary expansion testing (BET) framework. Through simple mathematics, we convert the dependence detection problem to a multiple testing problem....
