Detail config for multi-class model

[opjang5]

Hi, I'm going to reproduce the multi-class model on the KITTI dataset. I set the class list as ('Car,' 'Pedestrian,' 'Cyclist') and even add some smaller spherical radius in every SA layer. However, I got worse results under pedestrian and cyclist. It's that correct? What is your configuration on a multi-class model? And how is the result of it?
