# BNNS.FusedParametersLayer

A layer object that wraps a fused layer and manages its deinitialization.

## Declaration

```swift
class FusedParametersLayer
```

## Overview

Overview Use a BNNS.FusedParametersLayer instance to fuse component layers with the following configurations: Convolution → Normalization Fully Connected → Normalization Transposed Convolution → Normalization Convolution → Quantization Fully Connected → Quantization Transposed Convolution → Quantization Arithmetic → Normalization
