CAOS: Conformal Aggregation of One-Shot Predictors
Teaching an AI a brand-new task from just one labeled example is fast—but how sure can you be about its answers?
CAOS (Conformal Aggregation of One‑Shot Predictors) is a new method from Maja Waldron that adds reliable confidence to one‑shot learning. Instead of trusting a single quick‑adapted model, CAOS aggregates multiple one‑shot predictors and uses a leave‑one‑out calibration step to squeeze the most out of scarce labels—no wasteful data splitting.
Even though it breaks some classical assumptions, CAOS comes with proofs that its confidence levels are reliable: its prediction sets include the correct answer at the promised rate. In tests on facial landmarking and RAFT text classification, CAOS produced smaller prediction sets than common baselines while keeping that reliability.
Confidence you can count on—from a single example.
