Classification of Solar Wind With Machine Learning [PDF]
Journal of Geophysical Research: Space Physics, 2017 AbstractWe present a four‐category classification algorithm for the solar wind, based on Gaussian Process. The four categories are the ones previously adopted in Xu and Borovsky (2015): ejecta, coronal hole origin plasma, streamer belt origin plasma, and sector reversal origin plasma. The algorithm is trained and tested on a labeled portion of the OMNI
