Abstract
Gene expression programming (GEP) is a data driven evolutionary technique that well suits for correlation mining of big data. This talk starts with a brief introduction to GEP and its application in mining the correlations of the parameter settings of Hadoop MapReduce for big data analytics. MapReduce is a major computing model in dealing with data intensive applications, and Hadoop has been widely taken up by the community due to its open source implementation of MapReduce. This talk then elaborates the computation nature of GEP in evolution based on an analysis of GEP schema theory, and as a result it presents a parallel GEP for computation speedup. The parallel GEP is evaluated on two data sets with complementary features. One data set has complex but loosely-coupled data samples in that each sample has a large number of input factors. The other data set has strongly correlated data samples but each sample has a small number of input factors. The computation complexity of the parallel GEP is further analyzed to demonstrate the high scalability of the parallel GEP in dealing with potential big data using a large number of CPU nodes. This work has recently been accepted for publication in IEEE Transactions on Evolutionary Computation with an impact factor of 10.629.
