EARCP: Self-Regulating Coherence-Aware Ensemble Architecture for Sequential Decision Making -- Ensemble Auto-Regule par Coherence et Performance

Researchers introduce EARCP, a new ensemble architecture for AI that dynamically weights different expert models based on performance and coherence. The system provides theoretical guarantees with sublinear regret bounds and has been tested on time series forecasting, activity recognition, and financial prediction tasks.

What Capable Agents Must Know: Selection Theorems for Robust Decision-Making under Uncertainty

Researchers prove 'selection theorems' showing that AI agents achieving low regret on prediction tasks must develop internal predictive models and belief states. The work demonstrates that structured internal representations are mathematically necessary, not just helpful, for competent decision-making under uncertainty.

Near-Optimal Regret for KL-Regularized Multi-Armed Bandits

Researchers developed a new analysis of KL-regularized multi-armed bandits (MABs) using KL-UCB algorithm, achieving near-optimal regret bounds. The study provides the first high-probability regret bound with linear dependence on the number of arms and establishes matching lower bounds, offering comprehensive understanding across all regularization regimes.
