Eureqa Smoothing Step
This is an optional step where the Eureqa application can automatically smooth your data.
Smoothing data can greatly improve both the speed and the likelihood of finding accurate solutions with the Eureqa formula search. Deciding whether or not to smooth implies some expert knowledge from the user that variables in the data are in fact smooth signals combined with noise.
To smooth a variable in Eureqa:
- Select the row corresponding to the variable you'd like to smooth. This will show the data in the bottom plot.
- Select an independent variable in the "Smooth vs." column to smooth against (e.g. "time").
- Select a confidence weight in the "Weight Smooth by" column if you have a confidence strength variable entered.
- Checkmark the "Enable Smooth" option to smooth.
Eureqa picks the best smooth using generalized cross-validation among cubic b-splines. If you data can benefit from more sophisticated pre-processing, you are encouraged to do so in another application of your choice and copy the result into Eureqa by hand.
