The input image sizes to $224$x$224$x$3($three color challenges$).$ The first convolution layer of the

network has $64$ filters $($each of which is $7$x$7$ in size$),$ the second volution layer has $641$x$1$ filters,

followed by $192$ convolution filters $($each with size $3$x$3).$ What are the number of tunable

parameters at second and third convolution layer, respectively? $[0\mathrm{.}5$ pt$]$
