public static class StringCharConcatOp

Methods

ChAverageConditional(StringDistribution, StringDistribution)

EP message to ch.

Declaration

public static DiscreteChar ChAverageConditional(StringDistribution concat, StringDistribution str)

Parameters

Type	Name	Description
StringDistribution	concat	Incoming message from `concat`.
StringDistribution	str	Incoming message from `str`.

Returns

Type	Description
DiscreteChar	The outgoing EP message to the `ch` argument.

Remarks

The outgoing message is a distribution matching the moments of ch as the random arguments are varied. The formula is proj[p(ch) sum_(concat,str) p(concat,str) factor(concat,str,ch)]/p(ch).

ConcatAverageConditional(StringDistribution, DiscreteChar)

EP message to concat.

Declaration

public static StringDistribution ConcatAverageConditional(StringDistribution str, DiscreteChar ch)

Parameters

Type	Name	Description
StringDistribution	str	Incoming message from `str`.
DiscreteChar	ch	Incoming message from `ch`.

Returns

Type	Description
StringDistribution	The outgoing EP message to the `concat` argument.

Remarks

The outgoing message is a distribution matching the moments of concat as the random arguments are varied. The formula is proj[p(concat) sum_(str,ch) p(str,ch) factor(concat,str,ch)]/p(concat).

LogAverageFactor(StringDistribution, StringDistribution, DiscreteChar)

Evidence message for EP.

Declaration

public static double LogAverageFactor(StringDistribution concat, StringDistribution str, DiscreteChar ch)

Parameters

Type	Name	Description
StringDistribution	concat	Incoming message from `concat`.
StringDistribution	str	Incoming message from `str`.
DiscreteChar	ch	Incoming message from `ch`.

Returns

Type	Description
Double	Logarithm of the factor's average value across the given argument distributions.

Remarks

The formula for the result is log(sum_(concat,str,ch) p(concat,str,ch) factor(concat,str,ch)).

LogEvidenceRatio(StringDistribution, StringDistribution, DiscreteChar)

Evidence message for EP.

Declaration

public static double LogEvidenceRatio(StringDistribution concat, StringDistribution str, DiscreteChar ch)

Parameters

Type	Name	Description
StringDistribution	concat	Incoming message from `concat`.
StringDistribution	str	Incoming message from `str`.
DiscreteChar	ch	Incoming message from `ch`.

Returns

Type	Description
Double	Logarithm of the factor's contribution the EP model evidence.

Remarks

The formula for the result is log(sum_(concat,str,ch) p(concat,str,ch) factor(concat,str,ch) / sum_concat p(concat) messageTo(concat)). Adding up these values across all factors and variables gives the log-evidence estimate for EP.

LogEvidenceRatio(String, StringDistribution, DiscreteChar)

Evidence message for EP.

Declaration

public static double LogEvidenceRatio(string concat, StringDistribution str, DiscreteChar ch)

Parameters

Type	Name	Description
String	concat	Constant value for `concat`.
StringDistribution	str	Incoming message from `str`.
DiscreteChar	ch	Incoming message from `ch`.

Returns

Type	Description
Double	Logarithm of the factor's contribution the EP model evidence.

Remarks

The formula for the result is log(sum_(str,ch) p(str,ch) factor(concat,str,ch)). Adding up these values across all factors and variables gives the log-evidence estimate for EP.

StrAverageConditional(StringDistribution, DiscreteChar)

EP message to str.

Declaration

public static StringDistribution StrAverageConditional(StringDistribution concat, DiscreteChar ch)

Parameters

Type	Name	Description
StringDistribution	concat	Incoming message from `concat`.
DiscreteChar	ch	Incoming message from `ch`.

Returns

Type	Description
StringDistribution	The outgoing EP message to the `str` argument.

Remarks

The outgoing message is a distribution matching the moments of str as the random arguments are varied. The formula is proj[p(str) sum_(concat,ch) p(concat,ch) factor(concat,str,ch)]/p(str).
