Stanford researcher calibrates synthetic data using historical tasks

arena · x · 2026-08-04

Carrie Tan presents a framework for doing inference on synthetic data by calibrating from historical tasks.

The method is designed for settings where ground-truth data for the current task does not exist. Instead of trusting synthetic data at face value, it learns from neighboring tasks that came earlier and corrects for bias introduced by models, time, and changing conditions.

The talk applies the idea to:

The bigger claim is that task-level patterns can substitute for missing task-level labels when the current task has no ground truth.
