Researchers have developed a new statistical test called the Martingale Kernel Independence Test (mHSIC) that significantly speeds up the process of checking for independence between variables. Unlike existing methods that require computationally intensive permutation tests, mHSIC uses a self-normalised statistic that converges to a standard normal distribution, allowing for a direct lookup. This new method is consistent against all fixed alternatives and runs at quadratic cost, offering a substantial speedup of 25-60x compared to traditional approaches while maintaining accuracy. AI
