Assessment of Empirical Troposphere Model GPT3 Based on NGL’s Global Troposphere Products [PDF]

Sensors, 2020
Tropospheric delay is one of the major error sources in GNSS (Global Navigation Satellite Systems) positioning. Over the years, many approaches have been devised which aim at accurately modeling tropospheric delays, so-called troposphere models.

A Regional Zenith Tropospheric Delay (ZTD) Model Based on GPT3 and ANN [PDF]

Remote Sensing, 2021
The delays of radio signals transmitted by global navigation satellite system (GNSS) satellites and induced by neutral atmosphere, which are usually represented by zenith tropospheric delay (ZTD), are required as critical information both for GNSS ...

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

Npj 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.
