Estimate Experiment Time Feature, Amazon EC2
Many of the experiments I conduct use the 'Optimize Selection (Evolutionary)' operator with a variable number of generations. Adding the above feature would allow me to reduce the maximum number of generations in order to conduct an initial test of an idea and only add additional generations if the test is successful.
I am also working on developing an Amazon EC2 instance that is configured with Ubuntu, RapidMiner, R, Amazon AWS Tools that I would provide free to the RapidMiner community. This would allow those of us with data mining problems that are easy to spread across multiple instances a quick way to conduct larger scale experiments. Having the functionality to estimate the length of time that an experiment would take would allow the user determine how many instances need to be launched in order to complete th processing in the desired amount of time.
I would be happy to provide additional details and/or help test the functionality I described above.
