Prediction Under Imperfect Compression: A Theory of Approximate MDL
Announce Type: new Abstract: Minimum Description Length (MDL) formalizes the principle of Occam's razor by optimizing the total description length: $L(\mathrm{model})+L(\mathrm{data} \ | \ \mathrm{model})$. For sequential prediction, the MDL method repeatedly selects a model with a minimum objective score of the observed prefix for the next step prediction. Classical MDL prediction theory shows that exact optimization of the MDL objective indeed provides a strong compression guarantee that...
Skill Reuse as Compression in Agentic RL
arXiv:2605.31509v1 Announce Type: new Abstract: Large language model agents trained with reinforcement learning (RL) often learn brittle, task-specific shortcuts. We hypothesize that agents generalize better when their successful trajectories are structurally compressible, decomposed into a small set of reusable abstract patterns. To formalize this, we introduce ReuseRL, which grounds agentic RL in the Minimum Description Length (MDL) principle.
Executable World Models for ARC-AGI-3 in the Era of Coding Agents
arXiv:2605.05138v2 Announce Type: replace Abstract: We evaluate an initial coding-agent system for ARC-AGI-3 in which the agent maintains an executable Python world model, verifies it against previous observations, refactors it toward simpler abstractions as a practical proxy for an MDL-like simplicity bias, and plans through the model before acting. The system is intentionally direct: it uses a scripted controller, predefined world-model interfaces, verifier programs, and a plan executor,...
Big fleet expansion: Navy to add 4 made-in-India warships, one survey vessel this month
NEW DELHI: Indian Navy is set to witness significant expansion in its naval fleet this month as it gears up to induct five indigenously-built naval platforms, including two Project 17A stealth frigates, a survey vessel and two anti-submarine warfare crafts. The made-in-India vessels will enhance maritime security, combat readiness and coastal defence. The upcoming inductions also reflect on India's growing ability to design and construct sophisticated naval assets within the country,...
