# init(input:output:fusedLayerParameters:filterParameters:)

Creates a new fused layer from an array of layer parameters.

## Declaration

```swift
convenience init?(input: BNNSNDArrayDescriptor, output: BNNSNDArrayDescriptor, fusedLayerParameters: [any FusableLayerParameters], filterParameters: BNNSFilterParameters? = nil)
```

## Parameters

- `input`: The descriptor of the input.
- `output`: The descriptor of the output.
- `fusedLayerParameters`: An array that contains the parameters of the fused layers.
- `filterParameters`: The runtime filter parameters.
