Post-Hurricane Damage Assessment Using Satellite Imagery and Geolocation Features

no code implementations15 Dec 2020 Quoc Dung Cao, Youngjun Choe

In this work, a creative choice of the geolocation features was made to provide extra information to the imagery features, but it is up to the users to decide which other features can be included to model the physical behavior of the events, depending on their domain knowledge and the type of disaster.

Splitting Gaussian Process Regression for Streaming Data
