AvgPool#

AvgPool operation performs the computation following the below formulas. Variable names follow the standard Conventions.

\[\dst(n, c, oh, ow) = \frac{1}{DENOM} \sum\limits_{kh, kw} \src(n, c, oh \cdot SH + kh - PH_L, ow \cdot SW +kw - PW_L)\]

where,

when attribute exclude_pad is set to false, in which case \(DENOM = KH \cdot KW\),
when attribute exclude_pad is set to true, in which case \(DENOM\) equals to the size of overlap between an averaging window and images.

Operation Attributes#

Attribute Name	Description	Value Type	Supported Values	Required or Optional
`strides`	Controls the strides the window is moved	s64	A s64 list containing positive values	Required
`pads_begin`	Controls number of zeros to be add to the front/top/left of spatial dimensions, the attribute will be ignored when `auto_pad` attribute is specified to `same_upper`, `same_lower` or `valid`	s64	A s64 list containing non-negative values	Required
`pads_end`	Controls number of zeros to be add to the back/bottom/right of spatial dimensions, the attribute will be ignored when `auto_pad` attribute is specified to `same_upper`, `same_lower` or `valid`	s64	A s64 list containing non-negative values	Required
`kernel`	Size of pooling window	s64	A s64 list containing positive values	Required
`exclude_pad`	Controls whether the padded values are counted	bool	True, False	required
`rounding_type`	Controls how to do rounding	string	`floor` (default), `ceil`	Optional
