Gating Network
The gating network receives input tokens and computes weights for each expert network through a learned routing function.
top_k_experts = select_top_k(gate_weights, k=2)
output = Σ(w_i · expert_i(x)) for i in top_k_experts
Load Balancing
Load balancing ensures uniform expert utilization and prevents expert collapse through auxiliary loss functions.
