Probability Paths and the Structure of Predictions over Time

1 code implementation NeurIPS 2021 Zhiyuan Jerry Lin, Hao Sheng, Sharad Goel

Given a collection of such probability paths, we introduce a Bayesian framework -- which we call the Gaussian latent information martingale, or GLIM -- for modeling the structure of dynamic predictions over time.

Learning Neighborhood Representation from Multi-Modal Multi-Graph: Image, Text, Mobility Graph and Beyond

no code implementations6 May 2021 Tianyuan Huang, Zhecheng Wang, Hao Sheng, Andrew Y. Ng, Ram Rajagopal

Recent urbanization has coincided with the enrichment of geotagged data, such as street view and point-of-interest (POI).

Surveilling Surveillance: Estimating the Prevalence of Surveillance Cameras with Street View Data

no code implementations4 May 2021 Hao Sheng, Keniel Yao, Sharad Goel

In a detailed analysis of the 10 U. S. cities, we find that cameras are concentrated in commercial, industrial, and mixed zones, and in neighborhoods with higher shares of non-white residents -- a pattern that persists even after adjusting for land use.
