摘要
使用非线性规划中的变度量法BFGS算法和DFP算法给出了一种新的加速EM算法收敛的方法。
Based on the quasi-Newton acceleration method the nonlinear programming modified formula is used and a new method for the acceleration of the EM algorithm is presented. A comparison between the EM algorithm and the modified method is made. The new method has much faster convergence than the EM algorithm.
