Data Science Resources: Stellar Classification using Machine Learning Posted on June 4, 2016 by cambridgecoding Leave a comment 02/06/16 Tech Talk: Stellar Classification using Machine Learning – by Sandra Greiss As part of our series of Cambridge Coding Academy Tech Talks, this presentation explores Machine Learning applications in astrophysics. Abstract In this talk, I use the spectra (stellar flux vs wavelength) of identified stars to build a classifier which will detect the identity of the stars. Using a very simple non linear SVM, I achieve an 86% accuracy with my model. The next step is to use deep neural nets to achieve a better accuracy. |
