To Believe or Not to Believe Y our LLM: Iterative Prompting for Estimating Epistemic Uncertainty

Neural Information Processing Systems

We explore uncertainty quantification in large language models (LLMs), with the goal to identify when uncertainty in responses given a query is large. We simultaneously consider both epistemic and aleatoric uncertainties, where the former comes from the lack of knowledge about the ground truth (such as about facts or the language), and the latter comes from irreducible randomness (such as multiple possible answers).



As Sudanese city returns to life after two-year siege, drone threat lingers

Al Jazeera

Life is cautiously returning to the streets of Dilling, the second largest city in South Kordofan state, after the Sudanese army broke a suffocating siege that had isolated the area for more than two years. For months, the city had been encircled by the paramilitary Rapid Support Forces (RSF) and the Sudan People's Liberation Movement-North (SPLM-N), cutting off vital supply lines and trapping civilians in a severe humanitarian crisis. Al Jazeera Arabic's Hisham Uweit, reporting from Dilling, described a city "recovering slowly" from the economic strangulation. "For over two years, heavy siege conditions were imposed on the city. Movement disappeared, goods vanished and livelihoods narrowed," Uweit said.
