In this paper, we consider a composite difference-of-convex (DC) program, whose objective function is the sum of smooth convex with Lipschitz continuous gradient, proper closed and function, concave function. This problem has many applications in machine learning data science. The proximal DCA (pDCA), special case classical algorithm (DCA), as well two Nesterov-type extrapolated – ADCA (Phan et...

Objective — To discuss the application value of PDCA cyclical management in improving standard rate goods management, which is capable experience patients, and thus work efficiency sense comfort medical staffs by investigating non-standard outpatient area our hospital. Methods All diagnostic areas were evaluated, evaluation results showed that standardized stood at 53.3%. According to analysis ...
