Bilinear pooling as the global pooling operator

Pooling method		HEp-2 Cells		DR
First transition layer	Global pooling layer	MCA	p value	QK	p value
Max	Bilinear	$86.28\pm 0.30$	0.0000	$0.776\pm 0.004$	0.6932
Average	Bilinear	$\mathbf{88.17}\pm \mathbf{0.21}$	0.7421	$0.763\pm 0.003$	0.0000
Max	Average + bilinear	$86.05\pm 0.42$	0.0000	$0.774\pm 0.004$	0.1813
Average	Average + bilinear	$\mathbf{88.22}\pm \mathbf{0.29}$	–	$0.764\pm 0.005$	0.0002
Average	Average	$\mathbf{88.02}\pm \mathbf{0.19}$	0.1625	$\mathbf{0.777}\pm \mathbf{0.004}$	–

Convolution is applied at all the transition layers except the first one
