ISingleFeaturePredictionTransformer<TModel> Interface

Definition

An ISingleFeaturePredictionTransformer contains the name of the FeatureColumnName and its type, FeatureColumnType. Implementations of this interface, have the ability to score the data of an input IDataView through the Transform(IDataView)

public interface ISingleFeaturePredictionTransformer<out TModel> : Microsoft.ML.IPredictionTransformer<out TModel>, Microsoft.ML.ITransformer where TModel : class
type ISingleFeaturePredictionTransformer<'Model (requires 'Model : null)> = interface
    interface IPredictionTransformer<'Model (requires 'Model : null)>
    interface ITransformer
    interface ICanSaveModel
Public Interface ISingleFeaturePredictionTransformer(Of Out TModel)
Implements IPredictionTransformer(Of Out TModel), ITransformer

Type Parameters

TModel

The Microsoft.ML.IPredictor or ICalibrator used for the data transformation.

Derived
Implements

Properties

FeatureColumnName

The name of the feature column.

FeatureColumnType

Holds information about the type of the feature column.

IsRowToRowMapper

Whether a call to GetRowToRowMapper(DataViewSchema) should succeed, on an appropriate schema.

Model (Inherited from IPredictionTransformer<TModel>)

Methods

GetOutputSchema(DataViewSchema)

Schema propagation for transformers. Returns the output schema of the data, if the input schema is like the one provided.

(Inherited from ITransformer)
GetRowToRowMapper(DataViewSchema)

Constructs a row-to-row mapper based on an input schema. If IsRowToRowMapper is false, then an exception should be thrown. If the input schema is in any way unsuitable for constructing the mapper, an exception should likewise be thrown.

(Inherited from ITransformer)
Save(ModelSaveContext) (Inherited from ICanSaveModel)
Transform(IDataView)

Take the data in, make transformations, output the data. Note that IDataView's are lazy, so no actual transformations happen here, just schema validation.

(Inherited from ITransformer)

Extension Methods

Preview(ITransformer, IDataView, Int32)

Preview an effect of the transformer on a given data.

Append<TTrans>(ITransformer, TTrans)

Create a new transformer chain, by appending another transformer to the end of this transformer chain.

CreateTimeSeriesEngine<TSrc,TDst>(ITransformer, IHostEnvironment, Boolean, SchemaDefinition, SchemaDefinition)

TimeSeriesPredictionEngine<TSrc,TDst> creates a prediction engine for a time series pipeline. It updates the state of time series model with observations seen at prediction phase and allows checkpointing the model.
