Abstract

The Basics of Machine LearningWhen a person is pregnant, a key question is how to establish the "date" of the pregnancy. Classically, the date was based on the last menstrual period (LMP). For the past 3 decades or more, in high-resource countries, this has been done using "hospital-grade" ultrasound machines, with testing performed by trained sonographers. In many parts of the world, neither the machines nor the trained sonographers are accessible. In an article published in <i>NEJM Evidence</i>, Pokaprakarn et al.<sup>1</sup> asked whether a low-cost handheld ultrasound device combined with artificial intelligence (AI) could substitute for the expensive machines and trained sonographers.
