Methods

ConstantLog(Double, TElementDistribution)

Creates a weight function which maps every allowed sequence to a given value and maps all other sequences to zero. A sequence is allowed if all its elements have non-zero probability under a given distribution.

Declaration

public WeightFunctions<TSequence, TElement, TElementDistribution, TSequenceManipulator, TAutomaton>.MultiRepresentationWeightFunction<TDictionary> ConstantLog(double logValue, TElementDistribution allowedElements)

Parameters

Type	Name	Description
Double	logValue	The logarithm of the value to map every sequence to.
TElementDistribution	allowedElements	The distribution representing allowed sequence elements.

Returns

Type	Description
WeightFunctions.MultiRepresentationWeightFunction<TDictionary>	The created weight function

ConstantOnSupportOfLog(Double, WeightFunctions<TSequence, TElement, TElementDistribution, TSequenceManipulator, TAutomaton>.MultiRepresentationWeightFunction<TDictionary>)

Creates a weight function constant on the support of a given weight function.

Declaration

public WeightFunctions<TSequence, TElement, TElementDistribution, TSequenceManipulator, TAutomaton>.MultiRepresentationWeightFunction<TDictionary> ConstantOnSupportOfLog(double logValue, WeightFunctions<TSequence, TElement, TElementDistribution, TSequenceManipulator, TAutomaton>.MultiRepresentationWeightFunction<TDictionary> weightFunction)

Parameters

Type	Name	Description
Double	logValue	The logarithm of the desired value on the support of weightFunction.
WeightFunctions.MultiRepresentationWeightFunction<TDictionary>	weightFunction

Returns

Type	Description
WeightFunctions.MultiRepresentationWeightFunction<TDictionary>	The created weight function

Exceptions

Type	Condition
NotImplementedException	Thrown if if the weightFunction cannot be determinized.

FromAutomaton(TAutomaton)

Creates a weight function that is equal to the provided automaton on all sequences.

Declaration

public WeightFunctions<TSequence, TElement, TElementDistribution, TSequenceManipulator, TAutomaton>.MultiRepresentationWeightFunction<TDictionary> FromAutomaton(TAutomaton automaton)

Parameters

Type	Name	Description
TAutomaton	automaton	An automaton defining the weight function.

Returns

Type	Description
WeightFunctions.MultiRepresentationWeightFunction<TDictionary>	The created point mass weight function.

FromValues(IEnumerable<KeyValuePair<TSequence, Double>>)

Creates a weight function that assigns provided weights to provided sequences and zero weights to all other sequnces.

Declaration

public WeightFunctions<TSequence, TElement, TElementDistribution, TSequenceManipulator, TAutomaton>.MultiRepresentationWeightFunction<TDictionary> FromValues(IEnumerable<KeyValuePair<TSequence, double>> sequenceWeightPairs)

Parameters

Type	Name	Description
IEnumerable<KeyValuePair<TSequence, Double>>	sequenceWeightPairs	Pairs of sequences and corresponding weights

Returns

Type	Description
WeightFunctions.MultiRepresentationWeightFunction<TDictionary>	The created point mass weight function.

PointMass(TSequence)
