The ability to handle and analyse massive amounts of data has been progressively improved during the last decade with the growth of computing power and the opening up of the Internet era. Nowadays, machine learning algorithms have been widely applied in various fields of engineering sciences and in real world applications. However, currently, users of machine learning algorithms do not usually receive feedback on when a given algorithm will have finished building a model for a particular data set. While in theory such estimation can be obtained by asymptotic performance analysis, the complexity of machine learning algorithms means theoretical asymptotic performance analysis can be a very difficult task. This work has two goals. The first goal is to investigate how to use sampling-based techniques to predict the running time of a machine learning algorithm training on a particular data set. The second goal is to empirically evaluate a set of sampling-based running time prediction methods. Experimental results show that, with some care in the sampling stage, application of appropriate transformations on the running time observations followed by the use of suitable curve fitting algorithms makes it possible to obtain useful average-case running time predictions and an approximate time function for a given machine learning algorithm building a model on a particular data set. There are 41 WEKA (Witten Frank, 2005) machine learning algorithms are used for the experiments.
