MachineLearning / Client / predict

predict

MachineLearning.Client.predict(**kwargs)

Generates a prediction for the observation using the specified ML Model.

Note: Not all response parameters will be populated. Whether a response parameter is populated depends on the type of model requested.

Request Syntax

response = client.predict(
    MLModelId='string',
    Record={
        'string': 'string'
    },
    PredictEndpoint='string'
)

Parameters:

• MLModelId (string) –

  [REQUIRED]

  A unique identifier of the MLModel.

• Record (dict) –

  [REQUIRED]

  A map of variable name-value pairs that represent an observation.

  • (string) –

    The name of a variable. Currently it’s used to specify the name of the target value, label, weight, and tags.

    • (string) –

      The value of a variable. Currently it’s used to specify values of the target value, weights, and tag variables and for filtering variable values.

• PredictEndpoint (string) – [REQUIRED]

Return type:

dict
