Abstract: Multi-objective optimization is widely found in many fields, such as logistics, economics, engineering, or whenever optimal decisions need to be made in the presence of trade-offs between two or more conflicting objectives. The incorporation of probabilistic graphical approaches in evolutionary mechanism may enhance the iterative search process when interrelationships of the archived data has been learned, modeled, and used in the reproduction for multi-objective optimization. This talk will discuss the implementation of probabilistic graphical approaches in solving multi-objective optimization problems under the evolutionary paradigm. First, the problem of multi-objective optimization and its challenges such as complexities in terms of multimodal, high-dimensional, epistatic, deceptive, constrained, and uncertainties etc., will be studied. It will then show that the optimization problem can be solved using probabilistic graphical models. A binary stochastic neural network, named restricted Boltzmann machine (RBM), will be applied, and its learning, modeling and sampling mechanisms will be highlighted. The issues of scalability and uncertainty will also be discussed in this talk.
