MidSteer: Optimal Affine Framework for Steering Generative Models

Andrew Stepanov, Gregory Slabaugh, Ismail Elezi, Jiankang Deng, Martin Benning, Tatiana Gaintseva, Ziquan Liu

MidSteer is a general affine framework for concept steering in generative models that relaxes optimality assumptions of prior LEACE-based methods to enable directed minimal-disturbance transformations.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

We introduce MidSteer (Minimal Disturbance concept Steering), a more general affine framework for concept manipulation that relaxes these assumptions and enables directed, minimal-disturbance transformations.

C2weakest assumption

The assumptions under which LEACE-Switch provides an optimal affine solution hold for the specific concept manipulations considered; MidSteer relaxes them but still relies on affine transformations being sufficient for effective steering.
