Modifying Of Barzilai and Borwein Method for Solving Large-Scale Unconstrained Optimization Problems.
Khalil K. Abbo
In this paper we present a technique for computing the minimum value of an objective function in the frame of gradient descent methods based on combination of Barzilai and Borwein approximation of...
Comparison between some linear filter with application

Shortcut Transformation Between the Results of R-Mode and Q-Mode in Factor Analysis
- -,
In factor analysis, whenever the number of variables (m) less than the number of the experimental units (n) the procedure of R-mode should be applied, if (m) exceed (n) the Q-mode is the suitable...
