Recent experiments suggest that these language models use arbitrary facial characteristics to make weighty decisions about whether someone is competent or even likely to commit crimes. The findings were…

In their 2024 International Conference on Machine Learning paper, Monitoring AI-Modified Content at Scale: A Case Study on the Impact of ChatGPT on AI Conference Peer Reviews, Weixin Liang, Zachary Izzo, and their coauthors built a statistical method for estimating how much text in a large collection had been substantially written or rewritten by a…

The US government wants to spend $30.3 million over the next five years on an improved form of lie detector, according to a Department of Defense budget request. The program, called Polygraph+ or Polygraph Next, will focus on scoring algorithms that use artificial intelligence and machine learning and on a technique called “standoff sensing,” which…
