# AWS::Personalize::Solution HpoConfig
<a name="aws-properties-personalize-solution-hpoconfig"></a>

Describes the properties for hyperparameter optimization (HPO).

## Syntax
<a name="aws-properties-personalize-solution-hpoconfig-syntax"></a>

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

### JSON
<a name="aws-properties-personalize-solution-hpoconfig-syntax.json"></a>

```
{
  "[AlgorithmHyperParameterRanges](#cfn-personalize-solution-hpoconfig-algorithmhyperparameterranges)" : AlgorithmHyperParameterRanges,
  "[HpoObjective](#cfn-personalize-solution-hpoconfig-hpoobjective)" : HpoObjective,
  "[HpoResourceConfig](#cfn-personalize-solution-hpoconfig-hporesourceconfig)" : HpoResourceConfig
}
```

### YAML
<a name="aws-properties-personalize-solution-hpoconfig-syntax.yaml"></a>

```
  [AlgorithmHyperParameterRanges](#cfn-personalize-solution-hpoconfig-algorithmhyperparameterranges): 
    AlgorithmHyperParameterRanges
  [HpoObjective](#cfn-personalize-solution-hpoconfig-hpoobjective): 
    HpoObjective
  [HpoResourceConfig](#cfn-personalize-solution-hpoconfig-hporesourceconfig): 
    HpoResourceConfig
```
