I read a paper related to improve mapreduce straggler , the paper use prediction strategy called EWMA to predict the task process speed I don't read before about EWMA or any prediction algorithm so if you can help to tell me simple introduction how any algorithm can predict what will happen ? I searched on Wikipedia and other wepsites but all I get that it uses the previous values to estimate the next values , but it is still a vague idea to me
