I have an input-output dataset to be used in ANFIS modelling. I need to pre-process the data! I've already removed the outliers outside +/-3 standard deviation of the group mean! I've also employed the Moving Average Smoothing technique. The issue here is that the RMSE is still undesirably large! I need a more effective way to pre-process the data!

Perhaps you could give us an example plot or two? I would be interested in original data, then outlier-removed, then smoothed; and, of course, a line showing approximately what your ideal output would be.

I'm sorry for the delayed response! The two inputs are to be modeled separately with each of the outputs (Sugeno Fuzzy). Here are the download links for the data plots!
