Betting on Moments: Legendre Jumper Martingales for Online Exchangeability Testing
arXiv:2606.20859v2 Announce Type: replace Abstract: A fundamental assumption in statistics and machine learning is that ``the future looks like the past,'' formalized as exchangeability: the joint data distribution is order-invariant. In practice, this assumption is often violated due to distribution shifts over time.
