Researchers have developed a new online algorithm for recalibrating predictor sequences. This algorithm achieves optimal recalibration for Lipschitz proper losses within approximately \(\\varepsilon^{-3}\\) rounds. The work also introduces a \(\mathcal{K}_2\)-recalibration theorem that provides similar tradeoffs with a logarithmic factor. These algorithms can be combined with existing methods to achieve simultaneous \(\varepsilon\)-calibration and \(\varepsilon^2\)-calibeating for smooth proper losses, improving upon previous approaches that handled these properties separately.
