摘要
了解高维空间中的距离度量对于数据分析、机器学习和优化等多个领域至关重要。曼哈顿距离是多维环境中的一个基本度量,它通过对每个维度上的绝对差值求和来测量两点之间的距离。本研究探讨了曼哈顿距离在空间维度增加时的行为,解决了 "当维度数 n 增加时,两点间的曼哈顿距离会如何变化 "这一问题。我们通过数学推导和使用 Python 进行计算模拟,分析了曼哈顿距离的理论性质和统计行为。通过研究均匀分布在各维度固定区间的随机点,我们探索了曼哈顿距离的渐近行为,并从经验上验证了理论预期。我们的研究结果表明,随着维度的增加,曼哈顿距离的均值和方差呈现出可预测的趋势,这与理论预测非常吻合。不同维度下曼哈顿距离分布的可视化提供了对其行为的直观见解。这项研究有助于理解高维空间中的距离度量,为需要在多维领域中进行高效导航和分析的应用提供启示。
Asymptotic behavior of the Manhattan distance in $n$-dimensions: Estimating multidimensional scenarios in empirical experiments
Understanding distance metrics in high-dimensional spaces is crucial for
various fields such as data analysis, machine learning, and optimization. The
Manhattan distance, a fundamental metric in multi-dimensional settings,
measures the distance between two points by summing the absolute differences
along each dimension. This study investigates the behavior of Manhattan
distance as the dimensionality of the space increases, addressing the question:
how does the Manhattan distance between two points change as the number of
dimensions n increases?. We analyze the theoretical properties and statistical
behavior of Manhattan distance through mathematical derivations and
computational simulations using Python. By examining random points uniformly
distributed in fixed intervals across dimensions, we explore the asymptotic
behavior of Manhattan distance and validate theoretical expectations
empirically. Our findings reveal that the mean and variance of Manhattan
distance exhibit predictable trends as dimensionality increases, aligning
closely with theoretical predictions. Visualizations of Manhattan distance
distributions across varying dimensionalities offer intuitive insights into its
behavior. This study contributes to the understanding of distance metrics in
high-dimensional spaces, providing insights for applications requiring
efficient navigation and analysis in multi-dimensional domains.
