See the guide: Tensor Transformations > Fake quantization

Fake-quantize the 'inputs' tensor of type float via global float scalars min

and max to 'outputs' tensor of same shape as inputs.

[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.

This operation has a gradient and thus allows for training min and max values.

Args:

• inputs: A Tensor of type float32.
• min: A Tensor of type float32.
• max: A Tensor of type float32.
• num_bits: An optional int. Defaults to 8.
• narrow_range: An optional bool. Defaults to False.
• name: A name for the operation (optional).

Returns:

A Tensor of type float32.
