# tensorflow::ops::FakeQuantWithMinMaxArgs Class Reference # tensorflow:: ops:: FakeQuantWithMinMaxArgs ` #include ` 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. Args: - scope: A [Scope](https://www.tensorflow.org/versions/r2.5/api_docs/cc/class/tensorflow/scope#classtensorflow_1_1_scope) object
Returns: - ` https://www.tensorflow.org/versions/r2.5/api_docs/cc/class/tensorflow/output#classtensorflow_1_1_output ` : The outputs tensor.
