The ionosphere is the ionized part of the upper atmosphere of Earth, from about 48 km (30 mi) to 965 km (600 mi) above sea level, a region that includes the thermosphere and parts of the mesosphere and exosphere. The ionosphere is ionized by solar radiation. It plays an important role in atmospheric electricity and forms the inner edge of the magnetosphere. It has practical importance becau… WebWe have taken a dataset of Ionosphere and applied some machine learning technique (Gaussian Naive-Bayes, Decision Tree and Support Vector Machine) and predicted the presence/absence (i.e. Good/Bad) of structure in Ionosphere. flowhub app download
