This project is created for learning the real world application of linear algebra which contains some core concepts like determinants, matrix, eigen-value, eigen-vector, etc to create a real-world application like steganography, grafh-theory, analysis of spread of disease, image processing, cryptogra...
Social networks6form a subtype of network graphs that originated from graph theory. Graph theory is briefly the study of network graphs, which are mathematical representations used to model pairwise relations between objects. A graph is normally characterized by a set of nodes and edges which conne...
小杰:谱图理论(spectral graph theory) 4 什么是拉普拉斯矩阵?为什么GCN要用拉普拉斯矩阵? Graph Fourier Transformation及Graph Convolution的定义都用到图的拉普拉斯矩阵,那么首先来介绍一下拉普拉斯矩阵。 对于图 G=(V,E),其Laplacian矩阵的定义为 L=D-A,其中 L 是Laplacian 矩阵, D 是顶点的度矩阵(对角矩阵),...
However, it is impossible to acquire these coefficient measurements in practice and solving inverse problems with hidden physics is prohibitively expensive due to high uncertainty in simulation formulas17. Similar to the simulation by hidden fluid mechanics18, we achieved a high quantitative agreement ...

From the graph theory, a simple graph is defined as G=(V,E), where V is the set of nodes and E is the set of edges between nodes. In communication networks, the edges can be either directed or undirected, depending on the specific problems. Both nodes and edges can be associated wit...
Graph Theory in Probability Diffusion Processes and Stochastic Analysis on Manifolds 1 Introduction Content-Based Image Retrieval (CBIR) is a research topic related to computer vision area. The problem focuses on the search for a query image in a dataset and rank the results based on the similar...
Data science and machine learning have become an integral part of natural sciences, discussed as the fourth pillar in science, next to experiment, theory, and simulation1. Machine learning methods are increasingly applied in all steps of the materials development cycle, from finding initial candidate...
