Researchers have developed MAESTRO, a novel structured pruning framework designed to address the deployment bottleneck in Mixture-of-Experts (MoE) language models. Unlike previous methods that use local heuristics, MAESTRO models expert activation trajectories as Markov chains to capture cross-layer dependencies, providing a globally aware importance heuristic. This approach significantly improves performance retention, outperforming existing methods by up to 10.61% under a 50% compression regime, and demonstrates more consistent generalization across diverse tasks including safety, bias, and ethics.
