AvgPool

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.

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
