Network slimming through sparse channel-scale learning

Contribution grade

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

Reference score120,000Provisional editorial estimate of this exact contribution; its grade is assessed separately.

What changed

Applied sparsity penalties to channel scaling factors, notably batch-normalization gamma, then removed low-scale channels and fine-tuned the narrower dense network.

Scientific scope

Applied sparsity penalties to channel scaling factors, notably batch-normalization gamma, then removed low-scale channels and fine-tuned the narrower dense network. Inherits channel pruning, batch normalization and sparsity regularization. Training, pruning and fine-tuning remain necessary; the search changes layer widths rather than discovering arbitrary architectures. Residual/pre-activation networks require channel-selection handling. Smaller operation counts do not prescribe identical latency gains across platforms.
