Feature Selection on a Flare Forecasting Testbed: A Comparative Study of 24 Methods
Atharv Yeoleka, Sagar Patel, Shreejaa Talla +4
The Space-Weather ANalytics for Solar Flares (SWAN-SF) is a multivariate time series benchmark dataset recently created to serve the heliophysics community as a testbed for solar f…
Multiscale IoU: A Metric for Evaluation of Salient Object Detection with Fine Structures
Azim Ahmadzadeh, Dustin J. Kempton, Yang Chen +1
General-purpose object-detection algorithms often dismiss the fine structure of detected objects. This can be traced back to how their proposed regions are evaluated. Our goal is t…
Towards Synthetic Multivariate Time Series Generation for Flare Forecasting
Yang Chen, Dustin J. Kempton, Azim Ahmadzadeh +1
One of the limiting factors in training data-driven, rare-event prediction algorithms is the scarcity of the events of interest resulting in an extreme imbalance in the data. There…
All-Clear Flare Prediction Using Interval-based Time Series Classifiers
Anli Ji, Berkay Aydin, Manolis K. Georgoulis +1
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 region…
How to Train Your Flare Prediction Model: Revisiting Robust Sampling of Rare Events
Azim Ahmadzadeh, Berkay Aydin, Manolis K. Georgoulis +3
We present a case study of solar flare forecasting by means of metadata feature time series, by treating it as a prominent class-imbalance and temporally coherent problem. Taking f…
