This checkpoint is designed for use with SatNav, the continuous-state vision-and-language navigation platform for satellite maps. The SatNav Uni-NaVid integration uses it to predict short action sequences from a language instruction and a stream of RGB observations.

Model

Starting checkpoint: Jzzhang/Uni-NaVid
Vision encoder: EVA-CLIP
Training data: SatNav-v0.1 offline trajectories
Training: 1 epoch, learning rate 1e-5
Action window: up to 4 actions

Repository name

uninavid-satnav: Uni-NaVid adapted to SatNav
continue: starts from the Uni-NaVid checkpoint
1ep: trained for one epoch
lr1e-5: uses a learning rate of 1e-5
