Deterministic annealing em algorithm
Web3. Deterministic quantum annealing expectation-maximization algorithm This section is the main part of this paper. We formulate DQAEM by quantizing the hidden variables f˙ … WebThe contribution of unlabeled data to the learning criterion induces local optima, but this problem can be alleviated by deterministic annealing. For well-behaved models of posterior probabilities, deterministic annealing expectation-maximization (EM) provides a decomposition of the learning problem in a series of concave subproblems.

WebIn particular, the EM algorithm can be interpreted as converg- ing either to a local maximum of the mixtures model or to a saddle point solution to the statistical physics system. An advantage of the statistical physics approach is that it naturally gives rise to a heuristic continuation method, deterministic annealing, for finding good solu- Webfails since EM depends on initial values and suffers from the problem of local optima.
