Researchers have introduced a new family of conformal test martingales called Legendre Jumper Martingales, designed to detect deviations from exchangeability in data. These martingales extend the Simple Jumper martingale by using polynomial betting functions of arbitrary degrees to identify variance, skewness, and higher-order deviations. The Variational Legendre Jumper addresses the state space expansion issue of the Product Legendre Jumper by using a mean-field approximation for linear time complexity. Empirical results on a real-world classification task show that these combined methods outperform single-degree martingales, with the composite variant being recommended for unknown shift timescales.
