This paper introduces DynHD, a hallucination detection method for diffusion large language models that analyzes denoising dynamics across token and temporal dimensions, achieving 84% AUROC on LLaDA-8B and Dream-7B without repeated sampling.
DROID-W introduces a dense differentiable bundle‑adjustment SLAM framework that models per‑pixel dynamic uncertainty from multi‑view consistency, runs at about 30 FPS on an RTX 5090, and dramatically reduces trajectory error on challenging outdoor datasets, outperforming prior dynamic SLAM methods.
The article reviews two ICLR papers by Haoxin Lin that advance world‑model dynamics from single‑step bootstrapping to any‑step direct prediction, introduce structured uncertainty via backtracking, and achieve stable full‑horizon roll‑outs of over a thousand steps, dramatically improving both online and offline reinforcement‑learning performance.
This article examines why regression models need uncertainty estimates, explains aleatoric and epistemic uncertainty, compares four neural‑network approaches (Mean + LogStd, Mean + LogVariance, MC Dropout, simplified PPO) on a concrete‑strength dataset, and analyzes their experimental performance and limitations.
The article offers a thorough examination of Facebook’s Prophet forecasting model, detailing its additive decomposition of trend, seasonality, holidays and regressors, the underlying Bayesian inference via Stan, the full training‑and‑prediction pipeline, data‑normalization tricks, uncertainty estimation, and practical source‑code insights for e‑commerce applications.
