Johns Hopkins Data Science Capstone -- Natural Language Processing via Text Prediction using N-Grams

Given n points on a sphere, how do you test whether they all lie in the same hemisphere? Not just north/south, east/west, but any hemisphere. This is equivalent to finding a plane through the origin so that all n points lie to one side of this plane. We give a deterministic algorithm with run time O(n^3).

In this project, we explore NOAA’s Storm Event dataset in order to answer two main questions. Across the United States, which types of events (1) are most harmful with respect to population health? and (2) have the greatest economic consequences? Across the board, the data show tornados and flash floods to be the most harmful. While tornados, excessive heat, and lightning pose the most threat to humans, hail, floods, and flash floods tend to destroy the most property and crops.
