# BNNSMHAProjectionParameters

A structure that contains multihead attention projection parameters.

```
struct BNNSMHAProjectionParameters
```

## Topics

### Initializers

[`init(target_desc:weights:bias:)`](/documentation/Accelerate/BNNSMHAProjectionParameters/init(target_desc:weights:bias:))

Returns a new multihead attention projection parameters structure from the specified parameters.

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

Returns a new multihead attention projection parameters structure.

### Instance Properties

[`target_desc`](/documentation/Accelerate/BNNSMHAProjectionParameters/target_desc)

The descriptor—which is either an input query, key, or value, or an output—of the main target of the operation.

[`weights`](/documentation/Accelerate/BNNSMHAProjectionParameters/weights)

The descriptor of the initial projection’s weights.

[`bias`](/documentation/Accelerate/BNNSMHAProjectionParameters/bias)

The descriptor of the initial projection’s bias.
