Classes

CustomStopWordsRemovingEstimator

IEstimator<TTransformer> for the CustomStopWordsRemovingTransformer.

CustomStopWordsRemovingEstimator.Options

Use stop words remover that can removes language-specific list of stop words (most common words) already defined in the system.

CustomStopWordsRemovingTransformer

ITransformer resulting from fitting a CustomStopWordsRemovingEstimator.

LatentDirichletAllocationEstimator

The LDA transform implements LightLDA, a state-of-the-art implementation of Latent Dirichlet Allocation.

LatentDirichletAllocationTransformer

ITransformer resulting from fitting a LatentDirichletAllocationEstimator.

LatentDirichletAllocationTransformer.ModelParameters

Provide details about the topics discovered by LightLDA.

NgramExtractingEstimator

Produces a vector of counts of n-grams (sequences of consecutive words) encountered in the input text.

NgramExtractingTransformer

ITransformer resulting from fitting an NgramExtractingEstimator.

NgramHashingEstimator

IEstimator<TTransformer> for the NgramHashingTransformer.

NgramHashingTransformer
StopWordsRemovingEstimator

IEstimator<TTransformer> for the CustomStopWordsRemovingTransformer.

StopWordsRemovingEstimator.Options

Use stop words remover that can remove language-specific list of stop words (most common words) already defined in the system.

StopWordsRemovingTransformer

ITransformer resulting from fitting a StopWordsRemovingEstimator.

TextFeaturizingEstimator

An estimator that turns a collection of text documents into numerical feature vectors. The feature vectors are normalized counts of word and/or character n-grams (based on the options supplied).

TextFeaturizingEstimator.Options

Advanced options for the TextFeaturizingEstimator.

TextNormalizingEstimator

IEstimator<TTransformer> for the TextNormalizingTransformer.

TextNormalizingTransformer

ITransformer resulting from fitting a TextNormalizingEstimator.

TokenizingByCharactersEstimator

IEstimator<TTransformer> for the TokenizingByCharactersTransformer.

TokenizingByCharactersTransformer

ITransformer resulting from fitting a TokenizingByCharactersEstimator.

WordBagEstimator

IEstimator<TTransformer> for the ITransformer.

WordBagEstimator.Options

Options for how the n-grams are extracted.

WordEmbeddingEstimator

Text featurizer which converts vectors of text tokens into a numerical vector using a pre-trained embeddings model.

WordEmbeddingTransformer

ITransformer resulting from fitting an WordEmbeddingEstimator.

WordHashBagEstimator

IEstimator<TTransformer> for the ITransformer.

WordTokenizingEstimator

Tokenizes input text using specified delimiters.

WordTokenizingTransformer

ITransformer resulting from fitting an WordTokenizingEstimator.

Structs

LatentDirichletAllocationTransformer.ModelParameters.ItemScore
LatentDirichletAllocationTransformer.ModelParameters.WordItemScore

Interfaces

IStopWordsRemoverOptions

Defines the different type of stop words remover supported.
