# BNNSLayerParametersDropout

A structure that contains the parameters of a dropout layer.

```
struct BNNSLayerParametersDropout
```

## Topics

### Initializers

[`init(i_desc:o_desc:rate:seed:control:)`](/documentation/Accelerate/BNNSLayerParametersDropout/init(i_desc:o_desc:rate:seed:control:))

Returns a new dropout layer parameters structure from the specified parameters.

[`init()`](/documentation/Accelerate/BNNSLayerParametersDropout/init())

Returns a new dropout layer parameters structure.

### Instance Properties

[`i_desc`](/documentation/Accelerate/BNNSLayerParametersDropout/i_desc)

The descriptor of the input.

[`o_desc`](/documentation/Accelerate/BNNSLayerParametersDropout/o_desc)

The descriptor of the output.

[`rate`](/documentation/Accelerate/BNNSLayerParametersDropout/rate)

The probability that the layer drops out an element or a group of elements.

[`seed`](/documentation/Accelerate/BNNSLayerParametersDropout/seed)

The seed for the random number generator which is ignored if zero.

[`control`](/documentation/Accelerate/BNNSLayerParametersDropout/control)

An 8-bit bit mask that indicates the dimension of the grouping of the dropout decision.
