# BNNSOptimizerSGDMomentumWithClippingFields

A structure that contains the fields of a stochastic gradient descent (SGD) with momentum optimizer that optionally clips the gradient by value or by norm.

```
struct BNNSOptimizerSGDMomentumWithClippingFields
```

## Topics

### Initializers

[`init(learning_rate:momentum:gradient_scale:regularization_scale:nesterov:regularization_func:sgd_momentum_variant:clipping_func:clip_gradients_min:clip_gradients_max:clip_gradients_max_norm:clip_gradients_use_norm:)`](/documentation/Accelerate/BNNSOptimizerSGDMomentumWithClippingFields/init(learning_rate:momentum:gradient_scale:regularization_scale:nesterov:regularization_func:sgd_momentum_variant:clipping_func:clip_gradients_min:clip_gradients_max:clip_gradients_max_norm:clip_gradients_use_norm:))

Returns a new SGD with momentum optimizer fields structure from the specified parameters.
