New BALLAST method enhances oceanographic vector field inference

Researchers have developed a new active learning methodology called BALLAST to improve the inference of time-dependent vector fields, particularly for oceanography. This method uses a physics-informed Gaussian process surrogate model and considers the future trajectories of measurement observers. BALLAST has demonstrated benefits in synthetic and high-fidelity ocean current models, and a novel GP inference method, VaSE, was also introduced to enhance sampling efficiency. AI
