tensorflow:: ops:: FakeQuantWithMinMaxArgs

#include <array_ops.h>

Fake-quantize the 'inputs' tensor, type float to 'outputs' tensor of same type.

Summary

Attributes

  • [min; max] define the clamping range for the inputs data.
  • inputs values are quantized into the quantization range ( [0; 2^num_bits - 1] when narrow_range is false and [1; 2^num_bits - 1] when it is true) and then de-quantized and output as floats in [min; max] interval.
  • num_bits is the bitwidth of the quantization; between 2 and 16, inclusive.

Before quantization, min and max values are adjusted with the following logic. It is suggested to have min <= 0 <= max . If 0 is not in the range of values, the behavior can be unexpected:

  • If 0 < min < max : min_adj = 0 and max_adj = max - min .
  • If min < max < 0 : min_adj = min - max and max_adj = 0 .
  • If min <= 0 <= max : scale = (max - min) / (2^num_bits - 1) , min_adj = scale * round(min / scale) and max_adj = max + min_adj - min .

Quantization is called fake since the output is still in floating point.
