Why Gaussian Processes Beat Neural Networks for Small‑Sample Regression with Uncertainty

This article explains how Gaussian Process Regression (GPR) provides a principled Bayesian alternative to neural networks for small‑sample regression, delivering both accurate predictions and calibrated uncertainty by defining a prior over functions, using kernel composition, marginal likelihood optimization, and efficient numerical techniques.

Managing LLM Hallucinations: Strategies, Metrics, and Layered Controls

The article examines why large language models hallucinate, categorizes factual, faithfulness, and reasoning hallucinations, critiques existing benchmarks, and proposes a layered governance framework—including training‑time RLHF/DPO, retrieval‑augmented generation, post‑generation verification, uncertainty quantification, and compliance considerations—to mitigate risks in production systems.

How QuCo‑RAG Replaces Model Confidence with Objective Evidence to Cut Hallucinations

QuCo‑RAG introduces a dynamic retrieval‑augmented generation framework that quantifies uncertainty using pre‑training corpus statistics, replacing unreliable model confidence with objective frequency and co‑occurrence evidence, achieving millisecond‑level hallucination detection, superior multi‑hop QA performance, and cross‑model transferability across various LLMs.
