Anomaly detection of ship behavior based on deep neural networks

•A HybridAttn-BiRNN model with temporal and feature attention is proposed for ship trajectory prediction.•An anomaly detection framework integrating HDBSCAN clustering and the HybridAttn-BiRNN model is established.•Multiple anomaly types are detected using threshold discrimination and feature deviat...
