| 摘 要： | 本文从变换Ｊａｃｏｂｉａｎ阵角度出发指出了ＥＭ算法收敛的必要条件，并给出了验证这一条件的近似方法，这为ＥＭ算法的实际应用提供了一定的帮助，而且避免了文章［２］，［４］中的纯数学条件

| Abstract: | Using the Jacobian matrix of a transformation this paper gives the necessary condition on the convergence of the EM algorithm and gives one Approximate method to justify the condition.The method is useful to practice use of the EM algorithm and the pure methematical condition on the convergence of the EM algorithm is avoided. |
