which loss is better? #5

Closed pyni closed 4 years ago

pyni commented 4 years ago

Hi, I find there are three losses in your code: loss_t,loss_rmat,loss_geodesic so, which loss is a best metrics to evaluate two translations (or two matrices)?

papagina commented 4 years ago

Hi pyni, in the three experiments in our paper, they achieve very close results. But some people told me that they found using L2 loss on the rotation matrices outperforms the geodesic one.

I see, thanks.
