Researchers have developed new theoretical frameworks to analyze the properties of nearest-neighbor methods in machine learning when data is sampled dependently. The study establishes convergence and moment bounds for these methods under various mixing conditions, demonstrating that dependence does not fundamentally alter the scale of nearest-neighbor neighborhoods. These findings are supported by experimental results on synthetic and real-world data, indicating the continued informativeness of nearest-neighbor geometry even with dependent sampling. AI
