# MLCFullyConnectedLayer

A layer that connects each input to each output within its layer.

```
class MLCFullyConnectedLayer
```

## Overview

This is also known as a dense layer.

## Topics

### Creating Fully Connected Layers

[`init(weights:biases:descriptor:)`](/documentation/MLCompute/MLCFullyConnectedLayer/init(weights:biases:descriptor:))

Creates a fully connected layer with the weights, biases, and convolution descriptor you specify.

[`MLCConvolutionDescriptor`](/documentation/MLCompute/MLCConvolutionDescriptor)

A configuration object you use to create a convolution or fully connected layer.

### Inspecting Fully Connected Layers

[`descriptor`](/documentation/MLCompute/MLCFullyConnectedLayer/descriptor)

The configuration object you use to create the fully connected layer.

[`weights`](/documentation/MLCompute/MLCFullyConnectedLayer/weights)

The weights tensor you use for the fully connected layer.

[`biases`](/documentation/MLCompute/MLCFullyConnectedLayer/biases)

The biases tensor you use for the fully connected layer.

[`biasesParameter`](/documentation/MLCompute/MLCFullyConnectedLayer/biasesParameter)

The biases tensor parameter you use for optimizer updates.

[`weightsParameter`](/documentation/MLCompute/MLCFullyConnectedLayer/weightsParameter)

The weights tensor parameter you use for optimizer updates.
