Robust Mosaicking of Lightweight UAV Images Using Hybrid Image Transformation Modeling

open access: yesRemote Sensing, 2020
This paper proposes a robust feature-based mosaicking method that can handle images obtained by lightweight unmanned aerial vehicles (UAVs). The imaging geometry of small UAVs can be characterized by unstable flight attitudes and low flight altitudes ...

Predicting United States Policy Outcomes with Random Forests [PDF]

open access: yesInstitute for New Economic Thinking Working Paper Series, 2020
Two decades of U.S. government legislative outcomes, as well as the policy preferences of high-income people, the general population, and diverse interest groups, were captured in a detailed dataset curated and analyzed by Gilens, Page et al. (2014). They found that the preferences of high-income earners correlated strongly with policy outcomes, while ...
