The “WekiInputHelper” is a simple application that can sit in between your feature extractor and Wekinator to do common types of processing on your features, including:

• min, max, average, standard deviation of a feature over an analysis window
• collecting input values into a fixed-length history buffer
• first- and second-order differences
• arbitrary mathematical expressions, including those with digital filter notation
• altering sending behaviour, including rate throttling, or sending only when a trigger condition is satisfied

Instructions for WekiInputHelper are here.
