Convolution output size per axis (Geron Ch 12, morie.fn grcos)

out = floor((in + 2p - d(k-1) - 1)/s) + 1. dropped_cells counts the input columns no window ever covers.

Usage

morie_geron_conv_output_size(
  in_size,
  kernel,
  padding = 0,
  stride = 1,
  dilation = 1
)

Arguments

in_size, kernel, padding, stride, dilation

Scalars or per-axis vectors.

Value

List with out_size, receptive_field, same_padding, dropped_cells, is_same.
