# BNNSOptimizerRMSPropFields

A structure that contains the fields of a root mean square propagation (RMSProp) optimizer.

```
struct BNNSOptimizerRMSPropFields
```

## Topics

### Initializers

[`init(learning_rate:alpha:epsilon:centered:momentum:gradient_scale:regularization_scale:clip_gradients:clip_gradients_min:clip_gradients_max:regularization_func:)`](/documentation/Accelerate/BNNSOptimizerRMSPropFields/init(learning_rate:alpha:epsilon:centered:momentum:gradient_scale:regularization_scale:clip_gradients:clip_gradients_min:clip_gradients_max:regularization_func:))

Returns a new RMSProp optimizer fields structure from the specified parameters.

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

Returns a new RMSProp optimizer fields structure.

### Instance Properties

[`learning_rate`](/documentation/Accelerate/BNNSOptimizerRMSPropFields/learning_rate)

A value that specifies the learning rate.

[`alpha`](/documentation/Accelerate/BNNSOptimizerRMSPropFields/alpha)

A constant that specifies smoothing.

[`epsilon`](/documentation/Accelerate/BNNSOptimizerRMSPropFields/epsilon)

A term that the optimizer adds to the denominator.

[`centered`](/documentation/Accelerate/BNNSOptimizerRMSPropFields/centered)

A Boolean value that specifies whether to use the centered variant.

[`momentum`](/documentation/Accelerate/BNNSOptimizerRMSPropFields/momentum)

The rate of momentum decay.

[`gradient_scale`](/documentation/Accelerate/BNNSOptimizerRMSPropFields/gradient_scale)

A value that specifies the gradient scaling factor.

[`regularization_scale`](/documentation/Accelerate/BNNSOptimizerRMSPropFields/regularization_scale)

A value that specifies the regularization scaling factor.

[`clip_gradients`](/documentation/Accelerate/BNNSOptimizerRMSPropFields/clip_gradients)

A Boolean value that specifies whether to clip the gradient between minimum and maximum values.

[`clip_gradients_min`](/documentation/Accelerate/BNNSOptimizerRMSPropFields/clip_gradients_min)

The values for the minimum gradient.

[`clip_gradients_max`](/documentation/Accelerate/BNNSOptimizerRMSPropFields/clip_gradients_max)

The values for the maximum gradient.

[`regularization_func`](/documentation/Accelerate/BNNSOptimizerRMSPropFields/regularization_func)

The variable that specifies the regularization function.
