Contrastive Conceptor Activation Steering (COAST): Unlocking Vision-Language-Action Models through Hidden States

In three linesCOAST (Contrastive Conceptor Activation Steering) improves Vision-Language-Action models by identifying and steering latent representations toward success-critical subspaces. Across three distinct architectures, COAST increases task success rates by +20% in simulation and +40% on real robots, without additional training.
