Researchers have developed TSMini, a novel model designed to improve the accuracy of trajectory similarity learning. This model addresses challenges in modeling trajectory granularity and effectively utilizing similarity signals within training data. TSMini incorporates a sub-view modeling mechanism for multi-granularity pattern learning and a k-nearest neighbor-based loss function to capture both absolute similarity values and relative ranks between trajectories. Experiments indicate that TSMini surpasses existing state-of-the-art models by an average of 15% in approximating common trajectory similarity measures. AI
