Abstract: To explore the anisotropic nature and improve computational efficiency, eigenvalue (EV-) analysis is adopted to implement the transfer matrix method (TMM), abbreviated as EV-TMM, enabling ...
The final, formatted version of the article will be published soon. The Q-matrix serves as a bridge that links items and attributes, and its accuracy affects the results of cognitive diagnosis.
Abstract: Sparse matrix reordering is an important step in Cholesky decomposition. By reordering the rows and columns of the matrix, the time of computation and storage cost can be greatly reduced.
