# 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 zero_point quantity multiplied by scale. The coordinate $$j$$ of scale and zero_point is the coordinate of output projected onto axes.

### Inputs¶

Name

Element Type

Shape

input

Any quantized type

Any

scale

Same as output

input shape projected onto axes

zero_point | Same as input | input shape projected onto axes

### Attributes¶

Name

Description

type

output element type; any real type

axes

Axis positions on which scale and zero_point are specified

### Outputs¶

Name

Element Type

Shape

output

type

Same as input

## Mathematical Definition¶

$\mathtt{output}_{i,j} = (\mathtt{input}_{i,j} - \mathtt{zero_point}_{j}) \mathtt{scale}_{j}$
