Dequantize
Dequantize // Maps quantized input to real output
Description
Produces a tensor of element type type
and the same shape as input
where the value of each coordinate i
of output
is the corresponding coordinate of
input
minus offset
quantity multiplied by scale
.
The coordinate j
of scale
and offset
is the coordinate of output
projected onto axes
.
