FFAD: A Novel Metric for Assessing Generated Time Series Data Utilizing Fourier Transform and Auto-encoder

no code implementations11 Mar 2024 Yang Chen, Dustin J. Kempton, Rafal A. Angryk

While the Fr\'{e}chet Inception Distance (FID) serves as the standard metric for evaluating generative models in image synthesis, a comparable metric for time series data is notably absent.

Towards Synthetic Multivariate Time Series Generation for Flare Forecasting

no code implementations16 May 2021 Yang Chen, Dustin J. Kempton, Azim Ahmadzadeh, Rafal A. Angryk

We utilize a flare forecasting benchmark dataset, named SWAN-SF, and design two verification methods to both quantitatively and qualitatively evaluate the similarity between the generated minority and the ground-truth samples.

How to Train Your Flare Prediction Model: Revisiting Robust Sampling of Rare Events

no code implementations12 Mar 2021 Azim Ahmadzadeh, Berkay Aydin, Manolis K. Georgoulis, Dustin J. Kempton, Sushant S. Mahajan, Rafal A. Angryk

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.

Toward Filament Segmentation Using Deep Neural Networks

no code implementations20 Nov 2019 Azim Ahmadzadeh, Sushant S. Mahajan, Dustin J. Kempton, Rafal A. Angryk, Shihao Ji

Despite the known challenges in the identification and characterization of filaments by the existing module, which in turn are inherited into any other module that intends to learn from such outputs, Mask R-CNN shows promising results.

Challenges with Extreme Class-Imbalance and Temporal Coherence: A Study on Solar Flare Data

no code implementations20 Nov 2019 Azim Ahmadzadeh, Maxwell Hostetter, Berkay Aydin, Manolis K. Georgoulis, Dustin J. Kempton, Sushant S. Mahajan, Rafal A. Angryk

This is in particular prevalent in interdisciplinary research where the theoretical aspects are sometimes overshadowed by the challenges of the application.

A Curated Image Parameter Dataset from Solar Dynamics Observatory Mission

no code implementations3 Jun 2019 Azim Ahmadzadeh, Dustin J. Kempton, Rafal A. Angryk

We provide a large image parameter dataset extracted from the Solar Dynamics Observatory (SDO) mission's AIA instrument, for the period of January 2011 through the current date, with the cadence of six minutes, for nine wavelength channels.
