# MPSCNNDilatedPoolingMaxGradient

A gradient dilated max pooling filter.

## Declaration

```swift
class MPSCNNDilatedPoolingMaxGradient
```

## Overview

Overview A gradient max pooling filter but the pixels selected in each “application” of the max pooling operation are exactly the same pixels that would be selected with dilated convolution
