QuantizationErrorMethod¶

Enum to select a method for quantization parameters’ selection:

class model_compression_toolkit.core.QuantizationErrorMethod(value)¶

Method for quantization threshold selection:

NOCLIPPING - Use min/max values as thresholds.

MSE - Use mean square error for minimizing quantization noise.

MAE - Use mean absolute error for minimizing quantization noise.

KL - Use KL-divergence to make signals distributions to be similar as possible.

Lp - Use Lp-norm to minimizing quantization noise.

HMSE - Use Hessian-based mean squared error for minimizing quantization noise. This method is using Hessian scores to factorize more valuable parameters when computing the error induced by quantization.
