GeoConv layer and Linear(4,16)

[gtheofilo]

Hello guys and good job for the great work. I was reading the GeoConv.py and I am wondering why a Linear(4, 16) is used before the Conv1D?

Why would someone want to span more dimensions and transform the given vector(loc_i) to a 16x4 one? Is there any intuitive explanation for this?

Thanks for your time
