Constructors

ClassificationTask(MachineLearningTableJobInput)

Initializes a new instance of ClassificationTask.

Properties

CvSplitColumnNames

Columns to use for CVSplit data.

FeaturizationSettings

Featurization inputs needed for AutoML job.

FixedParameters

Model/training parameters that will remain constant throughout training.

LimitSettings

Execution constraints for AutoMLJob.

LogVerbosity

Log verbosity for the job.

(Inherited from AutoMLVertical)
NCrossValidations

Number of cross validation folds to be applied on training dataset when validation dataset is not provided. Please note NCrossValidations is the base class. According to the scenario, a derived class of the base class might need to be assigned here, or this property needs to be casted to one of the possible derived classes. The available derived classes include AutoNCrossValidations and CustomNCrossValidations.

PositiveLabel

Positive label for binary metrics calculation.

PrimaryMetric

Primary metric for the task.

SearchSpace

Search space for sampling different combinations of models and their hyperparameters.

SweepSettings

Settings for model sweeping and hyperparameter tuning.

TargetColumnName

Target column name: This is prediction values column. Also known as label column name in context of classification tasks.

(Inherited from AutoMLVertical)
TestData

Test data input.

TestDataSize

The fraction of test dataset that needs to be set aside for validation purpose. Values between (0.0 , 1.0) Applied when validation dataset is not provided.

TrainingData

[Required] Training data input.

(Inherited from AutoMLVertical)
TrainingSettings

Inputs for training phase for an AutoML Job.

ValidationData

Validation data inputs.

ValidationDataSize

The fraction of training dataset that needs to be set aside for validation purpose. Values between (0.0 , 1.0) Applied when validation dataset is not provided.

WeightColumnName

The name of the sample weight column. Automated ML supports a weighted column as an input, causing rows in the data to be weighted up or down.
