In Token Choice routing, each token selects the top-k experts with the highest scores from N experts for processing, which naturally guarantees that each token is processed by at least one expert, but it cannot control the number of tokens each expert receives.

UnverifiedA typical MoE layer consists of several expert feed-forward networks and a router; the router assigns each token only to the Top-K experts with the highest scores.78% similarUnverifiedThe MoE architecture uses a lightweight router to decide which experts handle each input token, and in mainstream implementations each token typically activates only 2 to 8 experts.71% similarUnverifiedIn Mixture-of-Experts (MoE) models, each input token is routed to only 2–4 experts for processing, while the remaining experts remain dormant.69% similarUnverifiedIn a MoE architecture, all expert parameters must always be accessible, because the router cannot know in advance which experts each token will hit.68% similarUnverifiedEach expert in a MoE layer contains three key configurations: gate, up, and down; NatScale jointly evaluates the impact of the combination of the three on the overall error of the expert output, rather than evaluating a single component separately.68% similar
