Recently developed information retrieval technologies are based on the concept of a vector space. Data are modeled as a matrix, and a user's query of the database is represented as a vector. Relevant ...

Estimation for the linear model y = Xβ + e with unknown diagonal covariance matrix G is considered. The diagonal elements of G are assumed to be known functions of the explanatory variables X and an ...

Theoretical ecologists study matrix eigenvalues (λi) of the stability matrix S = DA to determine local stability [where diagonal matrix D =diag ()].

The Data Science Lab Matrix Inverse from Scratch Using SVD Decomposition with C# Dr. James McCaffrey of Microsoft Research presents a full-code, step-by-step tutorial on an implementation of the ...
