LearningModelPreview.EvaluateFeaturesAsync 方法

定义

命名空间:

Windows.AI.MachineLearning.Preview

已弃用。 异步计算变量实例的名称作为模型的输入和输出。

public:
 virtual IAsyncOperation<LearningModelEvaluationResultPreview ^> ^ EvaluateFeaturesAsync(IMap<Platform::String ^, Platform::Object ^> ^ features, Platform::String ^ correlationId) = EvaluateFeaturesAsync;

/// [Windows.Foundation.Metadata.RemoteAsync]

function evaluateFeaturesAsync(features, correlationId)

Public Function EvaluateFeaturesAsync (features As IDictionary(Of String, Object), correlationId As String) As IAsyncOperation(Of LearningModelEvaluationResultPreview)

参数

features

IMap<String,Object>

IDictionary<String,Object>

IMap<Platform::String,Platform::Object>

IMap<winrt::hstring,IInspectable>

要绑定为输入的特征。

correlationId

String

Platform::String

winrt::hstring

用于将计算结果与输出结果关联的值。

返回

IAsyncOperation<LearningModelEvaluationResultPreview>

评估结果。

属性

RemoteAsyncAttribute DeprecatedAttribute

注解

警告

这是一个已弃用的 API。 请改用 Windows.AI.MachineLearning 命名空间。

在评估之前，此方法执行 和内部检查 onn 特征约束，并将特征绑定为输入。 这是一种替代方法，分别绑定模型，然后评估模型，简化工作区资源的验证和创建。
