A Rapid and Efficient Optical Transients Identification Framework Based on a Multimodal Neural Network and Machine Learning Operations

The Astrophysical Journal Supplement Series
Wide-field small-aperture telescopes are generally used for transient observations in the optical band, as they can effectively capture images with moderate spatial resolution and depth in a cost-effective way.
