But there is a problem using maximum likelihood estimateit in censored data models, that is MLE may not existence.

但是对截尾数据用似然方法的一个问题是MLE可能不存在。

Using maximum likelihood criterion in clustering algorithms, the clusters have spherical or ellipsoidal receptive fields and match the distributes of patterns better.

采用最大似然准则的聚类算法其类别接受域为球形或椭球形，可以与模式的分布匹配更好。

Furthermore, by evaluating three parameters of wavelet coefficients "probability model using maximum likelihood method, self adaptively of the algorithm is achieved."

而且通过极大似然法估计小波系数概率模型中的三个参数，使算法达到自适应性。
