# BNNS.SparseParameters

A data structure that provides a hint to the sparsity function.

```
struct SparseParameters
```

## Topics

### Creating a Sparse Parameters Structure

[`init(type: BNNS.SparsityType, ratio: (numerator: UInt32, denominator: UInt32), targetSystem: BNNSTargetSystem)`](/documentation/Accelerate/BNNS/SparseParameters/init(type:ratio:targetSystem:))

Returns a new sparse parameters structure.

### Inspecting the Properties of a Sparse Parameters Structure

[`let ratio: (numerator: UInt32, denominator: UInt32)`](/documentation/Accelerate/BNNS/SparseParameters/ratio)

The sparsity ratio expressed as the numerator and the denominator.

[`let targetSystem: BNNSTargetSystem`](/documentation/Accelerate/BNNS/SparseParameters/targetSystem)

The target system.

[`let type: BNNS.SparsityType`](/documentation/Accelerate/BNNS/SparseParameters/type)

An enumeration that specifies special patterns, if any, in the sparsity.
