Pretrained Models

[vseib]

Hello,
I have a few questions regarding the pretrained weights.
A "few years" ago the link to download the pretrained models contained an archive with folder names with the pattern laserscan_XD or scenenn_XD where X denoted the dimensionality of the output feature.
However, the current link links to an archive with folders such as
embed_d12_p11_r17_a12_synth_norelu_m5
embed_d18_p11_r17_a12_real_norelu
embed_d12_shot_synth_l1

Are these different experiments or the same weights with other names?
I understand that d could be the dimensionality and p, r and a the subdivisions of the feature grid. But what is the synth and real? Maybe different datasets (real = laser scan and synth = scene NN)? What would the "m5" be and what are the different shot embedding?

Please help :)

Thank you in advance
Viktor
