WebJul 31, 2024 · We explore the application of normalizing flows for improving the performance of trajectory planning for autonomous vehicles (AVs). Normalizing flows provide an invertible mapping from a known prior distribution to a potentially complex, multi-modal target distribution and allow for fast sampling with exact PDF inference. WebIn Flow-GANs, we propose to use the modeling assumptions corresponding to a normalizing flow model for specifying the generative process. ... Unlike the case of MLE, we find that the Jacobian for ADV are ill-conditioned that suggests the following result: Adversarial learning shows a strong preference for distributions of low support.
