Towards Coupling Full-disk and Active Region-based Flare Prediction for Operational Space Weather Forecasting

1 code implementation11 Aug 2022 Chetraj Pandey, Anli Ji, Rafal A. Angryk, Manolis K. Georgoulis, Berkay Aydin

We utilized an equal weighted average ensemble of two base learners' flare probabilities as our baseline meta learner and improved the capabilities of our two base learners by training a logistic regression model.

All-Clear Flare Prediction Using Interval-based Time Series Classifiers

no code implementations3 May 2021 Anli Ji, Berkay Aydin, Manolis K. Georgoulis, Rafal Angryk

An all-clear flare prediction is a type of solar flare forecasting that puts more emphasis on predicting non-flaring instances (often relatively small flares and flare quiet regions) with high precision while still maintaining valuable predictive results.
