MCGrad Introduces Scalable Multicalibration for Machine Learning Models

Meta has integrated MCGrad, which auto‑discovers sub‑populations and scales to web‑size data; internal tests show modest noticeable gains in log loss and PRAUC. Read more: getnews.me/mcgrad-introduces-scalab... #mcgrad #multicalibration #meta

Study Examines Auditability and Geometry of Multicalibration Errors

Researchers propose two metrics—a dMC variant and an intersection‑based multicalibration distance—that meet the two key requirements. The paper spans 41 pages. Read more: getnews.me/study-examines-auditabil... #multicalibration #auditability
