Variational Visual Question Answering for Uncertainty-Aware Selective Prediction

Researchers demonstrate that variational Bayesian methods significantly improve Vision Language Models' reliability for Visual Question Answering tasks by enabling selective prediction with reduced hallucinations and overconfidence. The proposed Variational VQA approach shows particular strength at low error tolerances and offers a practical path to making large multimodal models safer without proportional computational costs.

Variational Routing: A Scalable Bayesian Framework for Calibrated Mixture-of-Experts Transformers

Researchers have developed Variational Mixture-of-Experts Routing (VMoER), a Bayesian framework that enables uncertainty quantification in large-scale AI models while adding less than 1% computational overhead. The method improves routing stability by 38%, reduces calibration error by 94%, and increases out-of-distribution detection by 12%.

On the Equivalence of Random Network Distillation, Deep Ensembles, and Bayesian Inference

Researchers establish theoretical connections between Random Network Distillation (RND), deep ensembles, and Bayesian inference for uncertainty quantification in deep learning models. The study proves that RND's uncertainty signals are equivalent to deep ensemble predictive variance and can mirror Bayesian posterior distributions, providing a unified theoretical framework for efficient uncertainty quantification methods.

Practical Bayesian Inference for Speech SNNs: Uncertainty and Loss-Landscape Smoothing

Researchers demonstrate that applying Bayesian inference to Spiking Neural Networks (SNNs) for speech processing smooths the irregular loss landscape caused by threshold-based spike generation. Testing on speech datasets shows improved performance metrics and more regular predictive landscapes compared to deterministic approaches.

Dynamics-Predictive Sampling for Active RL Finetuning of Large Reasoning Models

Researchers propose Dynamics-Predictive Sampling (DPS), a new method that improves reinforcement learning finetuning of large language models by predicting which training prompts will be most informative without expensive computational rollouts. The technique models each prompt's learning progress as a dynamical system and uses Bayesian inference to select better training data, reducing computational overhead while achieving superior reasoning performance.
