提出了一种从超大规模数据中分析共性和个性特征的新方法，以保证计算和存储的可处理性，从而缓解现代数据科学中的一个主要瓶颈--维数诅咒。这是通过利用所谓的多块数据结构中固有的冗余来实现的，多块数据结构表示在不同时间、角度或记录条件下对同一现象的多个观察。在张量分解(TDs)中，在提供外部向量积的性质和提取的特征之间的内在联系的基础上，通过将物理意义强加给其他无约束的因式分解方法，从多块数据中提取公共和个体信息。这可以大大降低后续分类过程的搜索空间的维数，并大大提高精度。对从部分相关的真实图像中大规模提取个体特征的多类分类任务的仿真证明了与TDS相关的“维数加持”的优势。

英文摘要：
A novel method for common and individual feature analysis from exceedingly large-scale data is proposed, in order to ensure the tractability of both the computation and storage and thus mitigate the curse of dimensionality, a major bottleneck in modern data science. This is achieved by making use of the inherent redundancy in so-called multi-block data structures, which represent multiple observations of the same phenomenon taken at different times, angles or recording conditions. Upon providing an intrinsic link between the properties of the outer vector product and extracted features in tensor decompositions (TDs), the proposed common and individual information extraction from multi-block data is performed through imposing physical meaning to otherwise unconstrained factorisation approaches. This is shown to dramatically reduce the dimensionality of search spaces for subsequent classification procedures and to yield greatly enhanced accuracy. Simulations on a multi-class classification task of large-scale extraction of individual features from a collection of partially related real-world images demonstrate the advantages of the "blessing of dimensionality" associated with TDs.
