Abstract
A method for training a migration scene-based trajectory prediction model is provided, a first trajectory prediction model and a plurality of candidate training samples are obtained; for any candidate training sample, a reference value corresponding to the candidate training sample is determined according to at least one of a trajectory feature corresponding to the candidate training sample or a prediction result of the first trajectory prediction model for the candidate training sample; target training samples are selected from the plurality of candidate training samples according to the reference values corresponding to the plurality of candidate training samples; and the first trajectory prediction model is trained according to the target training samples, to obtain a second trajectory prediction model, where the second trajectory prediction model is configured to predict traveling trajectories of obstacles in a migration scene.
