Classification of Transient Astronomical Object Light Curves Using LSTM Neural Networks

arXiv — cs.LGTuesday, November 25, 2025 at 5:00:00 AM
  • A recent study has introduced a bidirectional Long Short-Term Memory (LSTM) neural network designed to classify light curves of transient astronomical objects using data from the Photometric LSST Astronomical Time-series Classification Challenge (PLAsTiCC). The study reorganized the original fourteen object classes into five categories to mitigate class imbalance, achieving high performance in certain classifications while facing challenges with others.
  • This development is significant as it enhances the ability to classify and understand transient astronomical phenomena, which can lead to better insights into cosmic events. The strong performance in S-Like and Periodic classes indicates the potential of LSTM networks in astronomical data analysis, paving the way for future research and applications in this field.
  • The use of LSTM networks in this context reflects a broader trend in artificial intelligence where deep learning techniques are increasingly applied to complex data sets across various domains. Similar methodologies are being explored in other areas, such as real-time sign language translation and time series forecasting, highlighting the versatility and growing importance of LSTM and related neural network architectures in addressing diverse challenges.
