Solar Flare Prediction Using Long Short-term Memory (LSTM) and Decomposition-LSTM with Sliding Window Pattern Recognition
Zeinab Hassani, Davud Mohammadpur, Hossein Safari
We investigate the use of Long Short-Term Memory (LSTM) and Decomposition-LSTM (DLSTM) networks, combined with an ensemble algorithm, to predict solar flare occurrences using time-…
Galaxy Morphological Classification with Zernike Moments and Machine Learning Approaches
Hamed Ghaderi, Nasibe Alipour, Hossein Safari
Classifying galaxies is an essential step for studying their structures and dynamics. Using GalaxyZoo2 (GZ2) fractions thresholds, we collect 545 and 11,735 samples in non-galaxy a…
Solar rotation and activity for cycle 24 from SDO/AIA observations
Zahra Shokri, Nasibe Alipour, Hossein Safari
The differential rotation plays a crucial role in the dynamics of the Sun. We study the solar rotation and its correlation with solar activity by applying a modified machine learni…
Asymmetry of the spectral lines of the coronal hole and quiet Sun in the transition region
Razieh Hosseini, Pradeep Kayshap, Nasibe Alipour +1
The asymmetry of line profiles, i.e., the secondary component, is crucial to understanding the energy release of coronal holes (CH), quiet sun (QS), and bright points (BPs). We inv…
