DualOPSD: Closing the Feedback Loop in On-Policy Self-Distillation

On-policy self-distillation (OPSD) combines student generated trajectories with dense supervision from a privileged teacher of the same model. Its pointwise clipping protects the student from locally incompatible teacher directions, but the fixed teacher receives no feedback about the supervision the student rejects, w...

Visual Representation and History Modeling for Navigation World Models

Under shared-history workloads, Cached-Linear substantially reduces computation and memory compared with Global-Softmax, while Balanced GDN improves selected direct-prediction endpoints with efficient context reuse.

Efficient Geothermal Well-Control Optimization via Diffusion-Surrogate Reinforcement Learning

Real-time decision-making for enhanced geothermal systems (EGS) is challenging because long-term production periods involve high-dimensional control spaces and a large number of time-consuming high-fidelity hydrothermal simulations. Reinforcement learning provides a natural framework for state-dependent sequential cont...

DualOPSD: Adaptive Privileged Teachers for On-Policy Self-Distillation

DualOPSD, an asymmetric alternating framework that adapts both policies, reduces truncation across all three scales, and makes later supervision responsive to the learner and does not require another rollout.

DeltaFlow: Noise-Adaptive Bidirectional Gated Delta Networks for Embedded Language Flows

DeltaFlow is a promising alternative to dense attention for efficient continuous language denoising and noise-adaptive memory control and scheduled Temporal State Consistency to stabilize hidden representations across nearby noise levels are introduced.
