TransformerChain<TLastTransformer> Class

Definition

Namespace:

Microsoft.ML.Data

Assembly:

Microsoft.ML.Data.dll

Package:

Microsoft.ML v4.0.0-preview.24522.7

Source:

TransformerChain.cs

A chain of transformers (possibly empty) that end with a TLastTransformer. For an empty chain, TLastTransformer is always ITransformer.

C#

public sealed class TransformerChain<TLastTransformer> : IDisposable, Microsoft.ML.ITransformer, System.Collections.Generic.IEnumerable<Microsoft.ML.ITransformer> where TLastTransformer : class, ITransformer

Type Parameters

TLastTransformer

Inheritance

Object

TransformerChain<TLastTransformer>

Implements

ICanSaveModel ITransformer IEnumerable<ITransformer> IEnumerable IDisposable

Constructors

TransformerChain<TLastTransformer>(IEnumerable<ITransformer>, IEnumerable<TransformerScope>)	Create a transformer chain by specifying transformers and their scopes.
TransformerChain<TLastTransformer>(ITransformer[])	Create a transformer chain by specifying all the transformers. The scopes are assumed to be Everything.

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, PredictionEngineOptions)	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.
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.
