const is used to decorate the variable pointed to by the pointer, that is, the pointer is constant, if the const is on the right side of the asterisk, A const is a modifier of the pointer itself, i.e. the pointer itself is a constant. Thus, [1] and [2] are the same, all pointers to the content is constant (const placed in the position of the variable declarator independent), in this case, the content is not allowed to change operations, such as *a = 3; [3] for the pointer itself is a constant,

each iteration, the EM algorithm increases the logarithmic likelihood function (\theta) $ by the maximum Q function.2.EM algorithm increases the likelihood function value of the observed data after each iteration, namely: $P (y|\theta^{(i+1)}) \geq P (y|\theta^{(i)}) $In general, EM algorithm is convergent, but it is not guaranteed to converge to the global optimal.3.EM algorithm is widely used in the study of probabilistic models with implicit variables, the parameter estimation of Gaussian mi
