Abstract： The frequent occurrence of telecommunications fraud has brought huge economic losss to society， and traditionalfraud detection methods often perform poorly when faced with label noise.To this end，this paper proposes a new telecommunications fraud detection method （DNW-GCN） that combines graph convolution network （GCN）and dynamic noise sample weighting technology.This method performs feature aggregation through GCNand dynamicallyreduces the weightofnoise samples tosuppressits interferenceon model training.Experiments showthat DNW-GCN cansignificantly improve the detection accuracyand recallrate of malicious samples under diferent noise levels，and still maintains an accuracy rate of more than 96% and a recall rate of 84.7% in a 35% noise environment， demonstrating good performance.Noise immunity and robustness.
