# MulticlassPredictionTransformer<TModel> Class

## Definition

Base class for the ISingleFeaturePredictionTransformer<TModel> working on multi-class classification tasks.

public sealed class MulticlassPredictionTransformer<TModel> : Microsoft.ML.Data.SingleFeaturePredictionTransformerBase<TModel> where TModel : class
type MulticlassPredictionTransformer<'Model (requires 'Model : null)> = class
inherit SingleFeaturePredictionTransformerBase<'Model (requires 'Model : null)>
Public NotInheritable Class MulticlassPredictionTransformer(Of TModel)
Inherits SingleFeaturePredictionTransformerBase(Of TModel)

#### Type Parameters

TModel

An implementation of the Microsoft.ML.IPredictorProducing1

Inheritance

## Properties

 The name of the feature column used by the prediction transformer. (Inherited from SingleFeaturePredictionTransformerBase) The type of the prediction transformer (Inherited from SingleFeaturePredictionTransformerBase) The model. (Inherited from PredictionTransformerBase)

## Methods

 Schema propagation for this prediction transformer. (Inherited from SingleFeaturePredictionTransformerBase) Transforms the input data. (Inherited from PredictionTransformerBase)

## Explicit Interface Implementations

 (Inherited from PredictionTransformerBase) Gets a IRowToRowMapper instance. (Inherited from PredictionTransformerBase) Whether a call to GetRowToRowMapper(DataViewSchema) should succeed, on an appropriate schema. (Inherited from PredictionTransformerBase)

## Extension Methods

 Preview an effect of the transformer on a given data`. Create a new transformer chain, by appending another transformer to the end of this transformer chain. TimeSeriesPredictionEngine 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. TimeSeriesPredictionFunction creates a prediction function/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.
