Matters arising: a response to loneliness and suicide mitigation for students using GPT3-enabled chatbots. [PDF]

open access: yesNpj Ment Health Res
In their recent paper, Maples et al. surveyed users of the Replika app. Among their results, they reported that participants were relatively lonely and used Replika for diverse purposes, and emphasized that "3% reported that Replika halted their suicidal ideation". However, important context about how Replika has been marketed and used was missing.

VMF3/GPT3: refined discrete and empirical troposphere mapping functions [PDF]

open access: yesJournal of Geodesy, 2017
Incorrect modeling of troposphere delays is one of the major error sources for space geodetic techniques such as Global Navigation Satellite Systems (GNSS) or Very Long Baseline Interferometry (VLBI). Over the years, many approaches have been devised which aim at mapping the delay of radio waves from zenith direction down to the observed elevation ...

SciFix: Outperforming GPT3 on Scientific Factual Error Correction

open access: yes, 2023
Due to the prohibitively high cost of creating error correction datasets, most Factual Claim Correction methods rely on a powerful verification model to guide the correction process. This leads to a significant drop in performance in domains like scientific claims, where good verification models do not always exist. In this work, we introduce SciFix, a
