What the math gives to ML

The paper contains a transferable architectural idea: use a low-dimensional recurrent state to select the parameters of a token-specific operator, rather than selecting among fixed expert outputs. The key asset is factorized dynamic weight synthesis, which gives each token a task-conditioned linear map while keeping the instruction bank much smaller than a full set of dense experts. This should be tested first as a drop-in replacement for the Transformer MLP, with a stable state-space controller and explicit low-rank updates around a shared base matrix. The main falsifiable benefit is improved accuracy and data efficiency at equal parameter count, especially when long contexts require slowly changing computation.

State-Routed Low-Rank MLP

Replace the shared Transformer feed-forward matrix with a shared base matrix plus a token-dependent low-rank update synthesized from a recurrent state-space controller. Unlike mixture-of-experts, the token does not merely interpolate expert outputs: it changes the actual matrices used inside both gated projections and therefore creates a continuous family of token-specific operators. The low-rank restriction keeps parameter growth and compute modest while allowing the controller to implement…
