The MLPMEA 2015 workshop provides an excellent international forum for sharing knowledge and results in theory, methodology and applications of Machine Learning for developing predictive models for different engineering applications. Machine Learning models are efficient for handing complex prediction models due to their outstanding performance in handling large scale datasets with uniform characteristics and noisy data. Examples of MLPMEA 2015 topics of interest include building predictive models using Machine Learning to solve specific engineering problems such as regression and classification problems.
