SLiC-HF: Sequence Likelihood Calibration with Human Feedback [PDF]

arXiv.org, 2023
Learning from human feedback has been shown to be effective at aligning language models with human preferences. Past work has often relied on Reinforcement Learning from Human Feedback (RLHF), which optimizes the language model using reward scores ...

A Survey of Confidence Estimation and Calibration in Large Language Models [PDF]

North American Chapter of the Association for Computational Linguistics, 2023
Large language models (LLMs) have demonstrated remarkable capabilities across a wide range of tasks in various domains. Despite their impressive performance, they can be unreliable due to factual errors in their generations.

The IntCal20 Northern Hemisphere Radiocarbon Age Calibration Curve (0–55 cal kBP)

Radiocarbon: An International Journal of Cosmogenic Isotope Research, 2020
Radiocarbon (14C) ages cannot provide absolutely dated chronologies for archaeological or paleoenvironmental studies directly but must be converted to calendar age equivalents using a calibration curve compensating for fluctuations in atmospheric 14C ...

Effect of confidence and explanation on accuracy and trust calibration in AI-assisted decision making [PDF]

FAT*, 2020
Today, AI is being increasingly used to help human experts make decisions in high-stakes scenarios. In these scenarios, full automation is often undesirable, not only due to the significance of the outcome, but also because human experts can draw on ...

Marine20—The Marine Radiocarbon Age Calibration Curve (0–55,000 cal BP)

Radiocarbon: An International Journal of Cosmogenic Isotope Research, 2020
The concentration of radiocarbon (14C) differs between ocean and atmosphere. Radiocarbon determinations from samples which obtained their 14C in the marine environment therefore need a marine-specific calibration curve and cannot be calibrated directly ...

IntCal13 and Marine13 Radiocarbon Age Calibration Curves 0–50,000 Years cal BP

Radiocarbon: An International Journal of Cosmogenic Isotope Research, 2013
The IntCal09 and Marine09 radiocarbon calibration curves have been revised utilizing newly available and updated data sets from 14C measurements on tree rings, plant macrofossils, speleothems, corals, and foraminifera. The calibration curves were derived

Improving Calibration for Long-Tailed Recognition [PDF]

Computer Vision and Pattern Recognition, 2020
Deep neural networks may perform poorly when training datasets are heavily class-imbalanced. Recently, two-stage methods decouple representation learning and classifier learning to improve performance. But there is still the vital issue of miscalibration.

In-flight performance and calibration of the Infrared Array Camera (IRAC) for the Spitzer Space Telescope [PDF]

SPIE Astronomical Telescopes + Instrumentation, 2004
The Infrared Array Camera (IRAC) is one of three focal plane instruments on board the Spitzer Space Telescope. IRAC is a four-channel camera that obtains simultaneous broad-band images at 3.6, 4.5, 5.8, and 8.0 μm in two nearly adjacent fields of view ...

Effect of cosmic rays irradiation on the phase change characteristics of an on-orbit fixed point

European Physical Journal C: Particles and Fields, 2023
Using the phase change characteristics of fixed points to trace the temperature of a spaceborne calibration blackbody is an important technical means to carry out the high-precision on-orbit calibration of thermal infrared remote sensors.
