Researchers have developed a new sequential test for detecting distribution shifts in data, utilizing conformal test martingales (CTMs). Unlike existing CTM detectors that continuously update their reference set, this new method compares incoming samples to a fixed reference dataset. This approach prevents contamination from post-shift data, leading to faster detection and improved power while maintaining anytime-valid type-I error control. AI
