Promoter is a part of the DNA sequence that comes before the gene and is key as a regulator of genes. Promoter prediction helps determine gene position and analyze gene expression. Hence, it is of great importance in the field of bioinformatics. In bioinformatics research, a number of machine learning approaches are applied to discover new meaningful knowledge from biological databases. In this study, two learning approaches, expectation maximization clustering and support vector machine classifier (EMSVM) are used to perform promoter detection. Expectation maximization (EM) algorithm is used to identify groups of samples that behave similarly and dissimilarly, such as the activity of promoters and non-promoters in the first stage, while the support vector machine (SVM) is used in the second stage to classify all the data into the correct class category. We have applied this method to.. View More»
