Structured CNN filter pruning by weight magnitude

Contribution grade

Structured neural-network compression · Human-designed research method or resource

Reference score115,000Provisional editorial estimate of this exact contribution; its grade is assessed separately.

What changed

Ranked trained convolutional filters by absolute weight sums and removed corresponding feature maps and downstream kernels, producing smaller dense operations rather than isolated sparse weights.

Scientific scope

Ranked trained convolutional filters by absolute weight sums and removed corresponding feature maps and downstream kernels, producing smaller dense operations rather than isolated sparse weights. Filter magnitude is a practical proxy, with layer sensitivity and pruning ratios empirically selected. Greedy multi-layer selection is not globally optimal and residual links impose structural constraints. Accuracy recovery and speed depend on retraining, architecture and implementation, not only nominal filter/FLOP reductions.
