摘要:

时间序列、视频或文本等顺序数据可能很难分析,因为有序结构会产生复杂的依赖关系。其核心是不可交换性,在这个意义上,重新排序序列的元素可以完全改变其含义。我们使用一个经典的数学对象-张量代数-来捕捉这种依赖关系。为了解决高阶张量固有的计算复杂性,我们使用低秩张量投影的组合。这为神经网络提供了模块化和可扩展的构建块,这些构建块在标准基准上提供了最先进的性能,例如多变量时间序列分类和视频生成模型。

英文摘要:

Sequential data such as time series, video, or text can be challenging to analyse as the ordered structure gives rise to complex dependencies. At the heart of this is non-commutativity, in the sense that reordering the elements of a sequence can completely change its meaning. We use a classical mathematical object -- the tensor algebra -- to capture such dependencies. To address the innate computational complexity of high degree tensors, we use compositions of low-rank tensor projections. This yields modular and scalable building blocks for neural networks that give state-of-the-art performance on standard benchmarks such as multivariate time series classification and generative models for video.
