Expand description

1-D reflection padding forward pass.

Grid: pid = (b * C + c) * num_ol_tiles + ol_tile

For output position op:

  • ip = op - PAD_LEFT
  • if ip < 0: source = input[-ip]
  • if ip >= L: source = input[2*(L-1) - ip]
  • else: source = input[ip]

Constraints: PAD_LEFT < L, PAD_RIGHT < L.
