{"id":2916,"title":"Decoupled Entropic-Geometric Planning (DEGP): Verified Conditioning and a Measured Contact-Prediction Boundary in Latent World Models","abstract":"Gradient-based latent space planning faces a fundamental trade-off: maintaining high-entropy representations for robust perception under domain shift often yields ill-conditioned manifolds that destabilize trajectory optimization. DEGP introduces a framework designed to isolate gradient interference between representation learning and control dynamics via strict architectural separation. However, empirical evaluation demonstrates that structural decoupling alone is insufficient for closed-loop planning, uncovering a fundamental information-usability gap driven by contact-conditional prediction errors and cost signal suppression. To delineate these operational limits, we provide analytical proofs establishing guaranteed spectral bounds on the predictor’s Jacobian under distribution shifts. Furthermore, we validate DEGP across manipulation tasks, introducing a telemetry-based runtime contract that quantifies the operational boundaries where geometric conditioning preserves planning stability.","content":"Gradient-based latent space planning faces a fundamental trade-off: maintaining high-entropy representations for robust perception under domain shift often yields ill-conditioned manifolds that destabilize trajectory optimization.
