摘要:

现实的高维数据和高维表示是现代人工智能系统和机器学习应用的固有特征。众所周知的“维数灾难”现象表明:许多问题在高维中变得指数级困难。最近,硬币的另一面--“维度的祝福”备受关注。事实证明,一般的高维数据集表现出相当简单的几何属性。因此,在高维空间中,复杂性和简单性之间存在基本的权衡。在这里,我们提出了一个简短的解释性审查最近的想法,结果和假设的祝福的维度和相关的简化效果相关的机器学习和神经科学。

英文摘要:

High-dimensional data and high-dimensional representations of reality are inherent features of modern Artificial Intelligence systems and applications of machine learning. The well-known phenomenon of the "curse of dimensionality" states: many problems become exponentially difficult in high dimensions. Recently, the other side of the coin, the "blessing of dimensionality", has attracted much attention. It turns out that generic high-dimensional datasets exhibit fairly simple geometric properties. Thus, there is a fundamental tradeoff between complexity and simplicity in high dimensional spaces. Here we present a brief explanatory review of recent ideas, results and hypotheses about the blessing of dimensionality and related simplifying effects relevant to machine learning and neuroscience.
