New MAEMs interpret language model directions, outperform corpus search

By PulseAugur Editorial · [1 sources] ·

Researchers have developed Maximally-Activating Example Metamodels (MAEMs) to interpret directions within a language model's residual stream. These MAEMs generate text exemplars that strongly activate specific directions, offering a more scalable and verifiable method than traditional corpus search. Empirically, a MAEM trained on Qwen3.6-27B demonstrated superior performance in inverting held-out activations, identifying concepts behind steering vectors, and recovering LoRA backdoor payloads.

    Towards interpreting any residual stream direction by scaling activation inversion

    arXiv:2611.08465v1 Announce Type: cross Abstract: To interpret a direction in a language model's residual stream, we can look for text that strongly activates it. But when such text is found by scanning a corpus, it is limited to what that corpus contains. We develop Maximally-Ac…
