New instrument precisely measures Mamba model state usage and input-driven migration

Researchers have developed a new instrument to precisely measure how selective state-space models, like Mamba, utilize their internal modes. This tool allows for the exact quantification of mode contributions to a model's output, enabling the prediction of errors from dropping specific modes. Studies across the Mamba family, including Mamba-1, Mamba-2, and Falcon-Mamba, reveal that trained models dynamically reallocate their state space based on input data, with a significant portion of this migration attributed to input-dependent mechanisms rather than the timestep typically associated with selectivity.

IMPACT Provides a new tool for understanding and potentially optimizing the internal workings of state-space models like Mamba.

    An Exact Instrument for State Usage in Selective State-Space Models, and the Input-Driven Migration It Reveals

    Selective state-space models such as Mamba route information through a bank of first-order modes whose input coupling is set by a learned selection mechanism. We give an exact instrument for measuring how a trained model uses these modes. Because the state matrix is diagonal, eac…
