LearningModelSession.EvaluateFeaturesAsync 方法

定义

命名空间:

Windows.AI.MachineLearning

使用 特征中的特征值异步评估机器学习模型。

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

/// [Windows.Foundation.Metadata.RemoteAsync]
IAsyncOperation<LearningModelEvaluationResult> EvaluateFeaturesAsync(IMap<winrt::hstring, IInspectable const&> const& features, winrt::hstring const& correlationId);

[Windows.Foundation.Metadata.RemoteAsync]
public IAsyncOperation<LearningModelEvaluationResult> EvaluateFeaturesAsync(IDictionary<string,object> features, string correlationId);

function evaluateFeaturesAsync(features, correlationId)

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

参数

features

IMap<String,Object>

IDictionary<String,Object>

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

IMap<winrt::hstring,IInspectable>

用于评估模型的特征的映射。

correlationId

String

Platform::String

winrt::hstring

可选用户提供的用于连接输出结果的字符串。

返回

IAsyncOperation<LearningModelEvaluationResult>

计算的结果。

属性

RemoteAsyncAttribute

注解

此方法是采用 LearningModelBinding 的分离绑定 then 评估形式的替代方法。 它将采用传入的功能，为你创建 LearningModelBinding ，绑定特征，然后评估模型。

Windows Server

若要在 Windows Server 上使用此 API，必须使用带桌面体验的 Windows Server 2019。

线程安全

此 API 是线程安全的。
