Hi, I’m studying your GaussianLSS paper. I see the model predicts 7 map categories (lane, road_segment, road_divider, lane_divider, ped_crossing, walkway, carpark_area), but the paper reports higher-level categories (Drivable, Ped. Cross., Walkway, Divider). Could you clarify how these high-level categories are computed from the original ones? Thanks!
