Query: Pruning Filter in Filter   Pruning has become a very powerful and effective technique to compress and
accelerate modern neural networks. Existing pruning methods can be grouped into
two categories: filter pruning (FP) and weight pruning (WP). FP wins at
hardware compatibility but loses at the compression ratio compared with WP. To
converge the strength of both methods, we propose to prune the filter in the
filter. Specifically, we treat a filter $F \in \mathbb{R}^{C\times K\times K}$
as $K \times K$ stripes, i.e., $1\times 1$ filters $\in \mathbb{R}^{C}$, then
by pruning the stripes instead of the whole filter, we can achieve finer
granularity than traditional FP while being hardware friendly. We term our
method as SWP (\emph{Stripe-Wise Pruning}). SWP is implemented by introducing a
novel learnable matrix called Filter Skeleton, whose values reflect the shape
of each filter. As some recent work has shown that the pruned architecture is
more crucial than the inherited important weights, we argue that the
architecture of a single filter, i.e., the shape, also matters. Through
extensive experiments, we demonstrate that SWP is more effective compared to
the previous FP-based methods and achieves the state-of-art pruning ratio on
CIFAR-10 and ImageNet datasets without obvious accuracy drop. Code is available
