However, traditional vector- or matrix-variate-based methods are not suitable for higher-order data analysis due to the possible structural information loss, and this is where tensor-variate-based Gaussian graphical model comes in. In this chapter, we discuss the development of Gaussian graphical ...
The data size may take values like \\(1000^{1000}.\\) Instead one needs sparse representations for all quantities \\(\\,A,\\,x,\\,b.\\) The numerical tensor calculus offers very efficient tools for this purpose. In Section 14.1 we introduce tensor spaces and show typical examples. ...
体素化后的点云被转换成Sparse tensor的形式,并仅在稀疏分布的MP-POV(Most-Probable Positively-Occupied Voxels,由Positively-Occupied Voxels(POV)上采样得到,可以理解为尚不确定上采样得到的子体素为POV还是NOV)处进行卷积(SparseConv)以此减少计算复杂度。 将体素进行多尺度采样,使得模型可以利用同尺度和跨尺度的相关...

However, if data includes tensor (multiway) structure (e.g. space-time-measurements), some meaningful anomalies may remain invisible with these methods. Although tensor-based anomaly detection (TAD) has been applied within a variety of disciplines over the last twenty years, it is not yet ...
基于张量学习的多视图谱聚类算法(Tensor Learning-based Multi-view Spectral Clustering, TL-MSC)是一种先进的机器学习技术,它将多视图数据表示为高维张量,并利用张量分解和谱聚类来识别数据中的潜在群集结构。 这种算法尤其适用于处理具有多个不同视角或表示的数据集,例如图像、文本和社交网络数据。
