Selection based on internal expert activations requires a precomputation pass, while feeding multiple full representations separately into the same expert repeats that expert's computation, and under a fixed expert budget both approaches erode the efficiency advantage of MoE.

VerifiedMixture-of-Experts (MoE) models use a routing mechanism to select only a small number of experts for each inference pass, reducing per-inference computation, but the knowledge of the unselected experts cannot be invoked.76% similarVerifiedIn MoE implementations, without constraints, the router tends to concentrate token assignments to a small number of experts, leading to Expert Collapse.75% similarUnverifiedIn Expert Choice routing, each expert selects a fixed number of top-k tokens from all tokens according to its own preference; load balancing on the expert dimension is strictly guaranteed mathematically, but there may be cases where some tokens are not selected by any expert.74% similarUnverifiedThe routing logic in MoE architecture requires careful tuning; otherwise, load imbalance issues arise where some experts are overused while the rest remain idle.72% similarUnverifiedUnder the MoE architecture, VRAM needs to accommodate the weights of all experts, but compute consumption is reduced proportionally to the activation ratio.71% similar
