GoogLeNet incarnation of the Inception architecture (Receptive Field Calculation)

Where K = Kernel size, P= Padding, S= Stride

η_in = Number Of Input Feature, η_out = Number Of Output Feature

R_in = Input receptive Field, R_out = Output Receptive field

J_in = Input Jump, J_out = Output Jump(increase in jump)
