PredTuner is a Python library for predictive approximation autotuning.

PredTuner performs autotuning on approximation choices for a program using an error-predictive proxy instead of executing the program, to greatly speedup autotuning while getting results of comparable quality.

PredTuner is a main component of ApproxTuner.
