# AWS::SageMaker::Algorithm
<a name="aws-resource-sagemaker-algorithm"></a>

Create a machine learning algorithm that you can use in SageMaker and list in the Amazon Marketplace.

## Syntax
<a name="aws-resource-sagemaker-algorithm-syntax"></a>

To declare this entity in your Amazon CloudFormation template, use the following syntax:

### JSON
<a name="aws-resource-sagemaker-algorithm-syntax.json"></a>

```
