New Bayesian method improves trajectory reconstruction from sparse data

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new method called Hierarchical Bayesian Trajectory-Family Sampling (HB-TPM) designed for reconstructing and sampling trajectories from sparse data. This approach learns a family of smooth curves from source tasks and adapts them to targets with limited observations. HB-TPM has demonstrated significant improvements in reducing error rates for trajectory reconstruction and sampling compared to existing methods, showing a 21.0-41.8% reduction in mean sliced-Wasserstein distance on vector tasks and a 50.2% reduction in mean relative trajectory RMSE on simulated photon records.

    Stay on the Manifold: Hierarchical Bayesian Trajectory-Family Transfer for Sparse-Target Reconstruction and Sampling

    arXiv:2310.07801v2 Announce Type: replace Abstract: Where should reconstructions and new samples lie when a few observations reveal only fragments of a trajectory? We propose hierarchical Bayesian trajectory principal-manifold sampling (HB-TPM), which learns a family of smooth cu…
