The proposed network generates hiddennneuron units dynamically during the training phase. The simulationnresults show two exciting properties in the proposed neural network;nhigh-speed ...
The maximum likelihood estimation is a process of obtaining the value of population parameters by maximize the likelihood function for observed data. The likelihood function is defined as the product of the density function for all observed data set. ...

This paper deals with problems related to the estimation of a nonlinear multi-parameter model with additive Gaussian errors. We take an optimal experimental design approach to improving the efficiency of the maximum likelihood estimate (MLE). As is well-known in the literature, when an optimal exp...

Maximum likelihood estimation ML estimators of the parameters are points which maximize the log-likelihood function in the parameter space. The log-likelihood (lnL) function for the Azzalini type SN distribution is given bylnL=nln(2σ)−n2ln(2π)−12∑i=1n(xi−μσ)2+∑i=1nln(Φ(λ...
In this lecture we show how to performmaximum likelihood estimationof a Gaussian mixture model with theExpectation-Maximization (EM) algorithm. At the end of the lecture we discuss practically relevant aspects of the algorithm such as the initialization of parameters and the stopping criterion. ...
In comparison to the advantages mentioned above, this method is a slow and intense process. Furthermore, in the absence of a single data set, the error output is high. Thus, it also makes reproducibility of the results more difficult by the maximum likelihood estimation. ...
