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

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

Intcal04 Terrestrial Radiocarbon Age Calibration, 0–26 Cal Kyr BP [PDF]

Radiocarbon: An International Journal of Cosmogenic Isotope Research, 2004
A new calibration curve for the conversion of radiocarbon ages to calibrated (cal) ages has been constructed and internationally ratified to replace ImCal98, which extended from 0-24 cal kyr BP (Before Present, 0 cal BP = AD 1950).

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 ...

To calibrate or not to calibrate, that is the question

Water Research, 2023
Sensors used for control have become widespread in water resources recovery facilities during the strive for resource efficient operations. However, their accuracy is reliant on uncertain laboratory measurements, which are used for calibration and, in turn, to correct for sensor drift.

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 ...

Parity Calibration

CoRR, 2023
In a sequential regression setting, a decision-maker may be primarily concerned with whether the future observation will increase or decrease compared to the current one, rather than the actual value of the future observation. In this context, we introduce the notion of parity calibration, which captures the goal of calibrated forecasting for the ...
