The field of optimization and machine learning are increasingly interplayed and optimization in different problems leads to the use of machine learning approaches‎. ‎Machine learning algorithms work in reasonable computational time for specific classes of problems and have important role in extracting knowledge from large amount of data‎. ‎In this paper‎, ‎a methodology has been employed to optimize the precision of defect detection of concrete slabs depending on their qualitative evaluation‎. ‎Based on this idea‎, ‎some machine learning algorithms such as C۴.۵ decision tree‎, ‎RIPPER rule learning method and Bayesian network have been studied to explore the defect of concrete and to supply a decision system to speed up the defect detection process‎. ‎The results from the examinations show that the proposed RIPPER rule learning algorithm in combination with Fourier Transform feature extraction method could get a defect detection rate of ۹۳% as compared to other machine learning algorithms.
