Attribution-Guided and Coverage-Maximized Pruning for Structural MoE Compression

arXiv:2606.18304v1 Announce Type: cross Abstract: Mixture-of-Experts (MoE) models scale compute efficiently, yet remain expensive to deploy due to their substantial memory footprint and inference overhead. Prior compression methods mainly operate at the expert level, either removing entire experts or ranking experts by coarse-grained importance scores. However, such expert-wise decisions are often too coarse to capture fine-grained redundancy, leading to misallocated pruning budgets and limited compression. To address this problem, we observe that information within MoE experts is highly conce

Why this matters
Why now

The increasing scale and complexity of AI models, particularly MoEs, are pushing the boundaries of current compute capabilities, driving a need for more efficient architectures and deployment strategies.

Why it’s important

This research addresses a critical bottleneck in deploying advanced AI models by proposing methods to reduce their memory footprint and inference costs, making powerful AI more accessible and sustainable.

What changes

The potential to deploy large MoE models more efficiently could accelerate AI adoption in resource-constrained environments and reduce the operational costs for advanced AI applications.
