(), this can is used only to access the immediate SUPER-CL Ass ' s method. Super.super won ' t work. Also, a class outside the inheritance hierarchy can ' t use this technique. Methods can be static or non-static. Since the methods are independent, it doesn ' t matter. But If two methods have the same signature, declaring one as static and another as Non-static does not provide a valid ove Rload.It ' s a compile time error. Static methods don ' t participate in overriding, since they are resolv

document 16. Converts an all-connected layer to a convolution layer, and the first full-connection is converted to a 7x7 convolution. The second one converts to a 1x1 convolution. Resulting net is applied to the whole image by convolving the filters of each layer with the full-size input. The resulting output feature map is a class score map with the number channels equal to the number of classes, and the Var Iable spatial resolution
