Abstract: An orthogonal-gradient measurement matrix construction algorithm is proposed for reducing the maximum and average mutual-coherence of sensing matrix. It shrinks Gram matrix based on ...

The code loads training and validation datasets from CSV files. It creates user-item rating matrices and centers the ratings by subtracting user and item means. Gradient Descent Model: Initializes ...

In GAMA's manual, I observed that diffusion can be performed by customizing uniform/irregular gradient matrices, But when writing code, keyword matrices and propagation cannot be used simultaneously.
