Computational Essay: A Tour of the Cosmos

Project: Spectral Identification Classifier

Project Overview

The classifier function identifies 97 neutral elements, 8 most common ions, and 47 most common compounds and combinations, including the typical ones that are found in stars, planetary atmospheres, galaxies, and nebulae. The classifier function exhibits 86.2% accuracy when trained on numerical data using the NearestNeighbors method. The accuracy improves to 97.2% when the classifier is trained on images using the LogisticRegression method.
