Table 1. Summary of weight and output tensor sizes in basic blocks.

Block type	Input tensor size	Subblock	Weight sizea	Output tensor size
stride = 1	c × win × hin	First	$\frac{1}{4}{c}^2\times w\times h$	c × win × hin
		Second	$\frac{1}{4}{c}^2\times w\times h$	c × win × hin
stride = 2		First	$\frac{1}{2}{c}^2\times w\times h$	$2c\times \frac{w_{in}}{2}\times \frac{h_{in}}{2}$
		Second	c2 × w × h	$2c\times \frac{w_{in}}{2}\times \frac{h_{in}}{2}$

Note:

^aWeight size denotes the number of weight filter’s parameters.
