Title/项目名称

Tensor Dimension Reduction for Multimodal Data and its Application in EEG Analysis(多模态张量降维方法研究和在EEG数据分析中的应用)

Abstract/项目简介

Multimodal data analysis, driven by the increasing variety of data types in applications, has attracted much interest in statistics, focusing on encoding different modalities into a common representation space to build predictive models or explore relationships between modalities. The main goal of the project is to build models to describe complicated dependencies between modalities. This is particularly challenging when at least one modality is a tensor due to the complexity of tensor structures. Our idea is to introduce a novel Structural Equation Model (SEM) based tensor matrix factorisation model to simultaneously extract latent scores and build relationships between modalities. The context of the proposal is the study of insomnia patients, where EEG data and questionnaire responses are analysed to understand the relationship between these very different types of data. The project outlines four specific problems, including the development of new tensor matrix factorisation models, the investigation of identifiability conditions, the measurement of non-linear dependence in tensor decomposition, and the study of functional connectivity models in the context of tensor matrix factorisation. statistical inference, implementation tools, optimisation algorithms and theory of both statistical and optimisation errors will be studied. Applications to the analysis of other wearable and mobile data will also be explored. The project will include but is not limited to the following four topics (1) SEM-based tensor matrix factorization model; (2) Nonlinear tensor matrix factorisation models and identifiability; (3) Tensor Decomposition with a measure of nonlinear dependence; (4) Functional connectivity analysis based on factorisation model.

由于在实际应用中的数据类型日益多样化,多模态数据分析引起了统计学界的极大兴趣。其核心在于将不同模态的数据编码到一个共同的空间中,以建立预测模型或探索各模态之间的关系。该项目的主要目标是建立模型来描述模态之间潜在的依赖关系。由于涉及张量结构的复杂性,当至少一种模态为张量时,这项工作尤其具有挑战性。我们的思路是引入一种新颖的基于结构方程模型的张量矩阵因式分解模型,以同时提取潜在变量并建立模态之间的关系。该项目的背景是针对失眠症患者的研究,通过分析脑电图数据和问卷答复来了解这些截然不同数据类型之间的关系。该项目包含了四个具体问题,包括开发新的张量矩阵因式分解模型、研究可识别性条件、测量张量分解中的非线性依赖性以及在张量矩阵因式分解背景下研究功能连接模型。该项目研究范围涵盖了统计推断、实现工具、优化算法以及统计和优化误差理论。此外,还将探讨该方法在其他可穿戴和移动数据分析方面的应用潜力。该项目将包括但不限于以下四个主题:(1)基于结构方程模型的张量矩阵因式分解模型;(2)非线性张量矩阵因式分解模型与可识别性;(3)考虑非线性依赖的张量分解;(4)基于因式分解模型的功能连接分析。
