SwinYNet: Transformer Model for Efficient FRB Search

SwinYNet represents a significant advancement in Fast Radio Burst (FRB) detection and analysis. By employing a transformer-based multi-task model, it achieves high accuracy and efficiency in detecting FRBs, segmenting signals, and estimating parameters directly from time-frequency data. The model's ability to operate without computationally expensive de-dispersion preprocessing is a key advantage, enabling real-time searches on a single consumer-grade GPU.

The model's performance on the FAST-FREX dataset, with an F1 score of 97.8%, a recall of 95.7%, and a precision of 100%, demonstrates its superiority over conventional tools and recent AI-based baselines. Its low false positive rate of 0.28% on CRAFTS data further underscores its robustness. The identification of two pulsar candidates, confirmed as known pulsars, highlights its practical utility.

However, the model's reliance on simulated data for training raises concerns about its generalizability to real observational data. While the study demonstrates its effectiveness on specific datasets, further validation is needed to assess its performance in diverse observational settings. Despite this limitation, SwinYNet's capabilities position it as a valuable tool for advancing FRB research and automating radio data analysis.
