Online Domain Adaptation for Occupancy Mapping [article]

Anthony Tompkins, Ransalu Senanayake, Fabio Ramos
2020 arXiv   pre-print
We validate various domain adaptation paradigms through a series of experiments, ranging from inter-domain feature transfer to simulation-to-real-world feature transfer.  ...  Further, with the use of high-fidelity driving simulators and real-world datasets, we demonstrate how parameters of 2D and 3D occupancy maps can be automatically adapted to accord with local spatial changes  ...  If the type of source and target domains are the same, as in occupancy mapping, the transfer process is called domain adaptation (DA).  ...
