padding

padding : enum, type of padding to apply.
Default value “VALID”.

• EXPLICIT : Padding is manually defined through the explicit_padding parameter.
• SAME_UPPER : Pads the input so that output_shape = ceil(input_shape / strides). If the padding is odd, the extra pixel is added at the end.
• SAME_LOWER : Same behavior as ‘SAME_UPPER’, but the extra pixel is added at the beginning.
• VALID : No padding is applied. The operation only uses the fully covered regions of the input.
