Mamba-2 interpretation probes miss half of state sink

By PulseAugur Editorial · [1 sources] ·

Researchers have identified a significant limitation in how Mamba-2's internal workings are understood. They found that standard probing techniques, which aim to link representational signatures to computational execution, only capture a fraction of the model's 'state sink' mechanism. A larger, 'detection layer' with similar representational patterns was missed by these single-bucket probes, highlighting a gap between representational similarity and actual functional execution in the model.

    Detection vs. Execution: Single-Bucket Probes Miss Half the Mamba-2 State Sink

    arXiv:2606.00930v1 Announce Type: cross Abstract: Mechanistic interpretability often assumes that probes identifying a representational signature also identify the circuit executing the corresponding computation. We show that this assumption can fail systematically in Mamba-2. St…
