Constructors

StringDictionaryWeightFunction()

Declaration
public StringDictionaryWeightFunction()

Methods

AsAutomaton()

Converts the current StringDictionaryWeightFunction to a deterministic automaton, compressing shared suffixes. When the current StringDictionaryWeightFunction is normalized, the resulting automaton is stochastic.

Declaration
public override StringAutomaton AsAutomaton()
Returns
Type Description
StringAutomaton

A deterministic StringAutomaton.

GetLogNormalizerOfProduct(StringDictionaryWeightFunction)

Computes the logarithm of the normalizer (sum of values of the weight function on all sequences) of the product of the current and the given weight functions.

Declaration
protected override double GetLogNormalizerOfProduct(StringDictionaryWeightFunction weightFunction)
Parameters
Type Name Description
StringDictionaryWeightFunction weightFunction
Returns
Type Description
Double

The logarithm of the normalizer.

Product(StringDictionaryWeightFunction)

Computes the product of the current weight function and a given one.

Declaration
public override StringDictionaryWeightFunction Product(StringDictionaryWeightFunction weightFunction)
Parameters
Type Name Description
StringDictionaryWeightFunction weightFunction
Returns
Type Description
StringDictionaryWeightFunction

The computed product.

SetDistinctWeights(IEnumerable<KeyValuePair<String, Weight>>)

Replaces the internal sequence to weight dictionary with a new one using the supplied sequenceWeightPairs. If the supplied collection is expected to not contain multiple entries for the same sequence.

Declaration
protected override void SetDistinctWeights(IEnumerable<KeyValuePair<string, Weight>> sequenceWeightPairs)
Parameters
Type Name Description
IEnumerable<KeyValuePair<String, Weight>> sequenceWeightPairs
Overrides
Microsoft.ML.Probabilistic.Distributions.Automata.WeightFunctions<System.String, System.Char, Microsoft.ML.Probabilistic.Distributions.ImmutableDiscreteChar, Microsoft.ML.Probabilistic.Distributions.Automata.StringManipulator, Microsoft.ML.Probabilistic.Distributions.Automata.StringAutomaton>.DictionaryWeightFunction<Microsoft.ML.Probabilistic.Distributions.Automata.StringDictionaryWeightFunction>.SetDistinctWeights(System.Collections.Generic.IEnumerable<System.Collections.Generic.KeyValuePair<System.String, Microsoft.ML.Probabilistic.Distributions.Automata.Weight>>)
Remarks

Should only ever be called in factory methods.

SetWeights(IEnumerable<KeyValuePair<String, Weight>>)

Replaces the internal sequence to weight dictionary with a new one using the supplied sequenceWeightPairs. If the supplied collection contains multiple entries for the same sequence, the weights for that sequence are summed.

Declaration
protected override void SetWeights(IEnumerable<KeyValuePair<string, Weight>> sequenceWeightPairs)
Parameters
Type Name Description
IEnumerable<KeyValuePair<String, Weight>> sequenceWeightPairs
Overrides

Remarks
