Structured Neuron Pruning in Deep Neural Networks Using Multi-Armed Bandits

arXiv:2606.07615v1 Announce Type: new Abstract: Deep neural networks often contain redundant hidden units. Removing individual weights can reduce parameter count, but unstructured sparsity is not always easy to exploit in standard dense implementations. This paper develops a structured pruning framework in which complete neurons are removed using multi-armed bandit (MAB) algorithms. Each candidate neuron is treated as an arm; pulling an arm temporarily masks that neuron, measures the change in loss on a sampled mini-batch, restores the neuron, and updates an estimate of its safe-removal reward

Why this matters
Why now

The continuous growth in deep neural network complexity necessitates more efficient architectural optimization techniques, making pruning increasingly relevant for practical application.

Why it’s important

Improving the efficiency of deep neural networks through structured pruning can lead to significant reductions in computational cost and energy consumption, impacting the scalability and deployability of AI models.
