    • Improving astronomical time-series classification via data augmentation with generative adversarial networks 
      García Jara, Germán Eduardo; Protopapas, Pavlos; Estévez Valencia, Pablo Antonio (IOP Publishing, 2022)
      Due to the latest advances in technology, telescopes with significant sky coverage will produce millions of astronomical alerts per night that must be classified both rapidly and automatically. Currently, classification ...
    • A novel, fully automated pipeline for period estimation in the EROS 2 data set 
      Protopapas, Pavlos; Huijse Heise, Pablo Andrés; Estévez Valencia, Pablo; Zegers, Pablo; Principe, José; Marquette, Jean Baptiste (IOP Publishing, 2015)
      We present a new method to discriminate periodic from nonperiodic irregularly sampled light curves. We introduce a periodic kernel and maximize a similarity measure derived from information theory to estimate the periods ...
    • Period Estimation in Astronomical Time Series Using Slotted Correntropy 
      Huijse Heise, Pablo Andrés; Estévez Valencia, Pablo; Zegers, Pablo; Príncipe, José C.; Protopapas, Pavlos (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS, 2011-06)
      In this letter, we propose a method for period estimation in light curves from periodic variable stars using correntropy. Light curves are astronomical time series of stellar brightness over time, and are characterized as ...
