This paper benchmarks LLMs against human verbal uncertainty markers from psychology literature and introduces VOCAL, an optimization-based algorithm that learns an optimal marker-to-uncertainty profile directly from LLM outputs, revealing systematic gaps between how LLMs and humans express confidence in language.
The post benchmarks a zero-GPU, CPU-only string-normalization entropy metric (Spanda) against semantic entropy across 1.5B–120B local and frontier models, finding that 7B–27B models are well-served by cheap exact-match entropy while 120B models collapse into identical confident hallucinations that even NLI models miss.
A new paper introduces CAGE, a framework combining generative models, adversarial discrimination, and conformal prediction to weight time series ensemble forecasts, showing improved robustness against outliers and noise on milk collection and monkeypox datasets.
The paper proposes EDAR, an entropy-driven adaptive routing framework that decides at inference time whether to answer a query with retrieval-augmented generation or escalate it to full long-context processing. EDAR retains 97.4% of the pure long-context baseline's accuracy while cutting token cost by 70.7%, escalating only 18.2% of queries on LongBench v2 and Infinity-Bench.
