Post-Hoc Sparse Coding of Latent Communication Between Vision-Language Model Agents
This work studies Vision Wormhole's redundancy by fitting a post-hoc sparse autoencoder to frozen Vision Wormhole activations and measuring reconstruction, downstream utility, feature reuse, and token-level interventions across nine reasoning benchmarks, and establishes strong post-hoc compressibility relative to the o...
