UnverifiedThe 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.72% similarUnverifiedIn 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.68% similarUnverifiedThe MoE architecture splits the feed-forward network (FFN) layers in the Transformer into multiple parallel experts, and each token is routed to only a few experts for computation.65% similarUnverifiedA 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.64% similarUnverifiedSparse mixture of experts (MoE) uses a routing gating network to select only a few experts to participate in computation for each input token, allowing the total parameter count to be very large while the activated parameters per token are few.64% similar
