Uncertainty Estimation using Variance-Gated Distributions

Researchers propose a variance-gated framework for uncertainty quantification in neural networks that decomposes predictive uncertainty using signal-to-noise ratios rather than traditional additive methods. The approach scales predictions by confidence factors derived from ensembles and reveals potential diversity collapse in committee machines, advancing how machine learning models evaluate per-sample uncertainty for high-risk applications.

Sample-efficient and Scalable Exploration in Continuous-Time RL

Researchers introduce COMBRL, a new reinforcement learning algorithm designed for continuous-time systems using nonlinear ordinary differential equations. The algorithm achieves sublinear regret and better sample efficiency compared to existing methods by combining probabilistic models with uncertainty-aware exploration.
