Switch Transformers: Scaling to Trillion Parameter Models with Simple and Efficient Sparsity

Paper summary

Switch Transformers simplify sparse expert routing and address communication and training instability. Selected experts increase parameter capacity without activating the entire model for each input, with large-scale training demonstrations.

Relevance to the project

An engineering comparison for specialization and batched work allocation if multiple neuron types are later explored. It is not a selected control-network design.

Language modelsMixture of expertsEfficient training

Active computation, total storage, and routing overhead are separate costs.
