java.lang.Enum<QueryEvidenceMode>

com.bayesserver.inference.QueryEvidenceMode

All Implemented Interfaces:

Serializable, Comparable<QueryEvidenceMode>

public enum QueryEvidenceMode
extends Enum<QueryEvidenceMode>

Determines how predictions on variables with evidence are performed.

Enum Constant Summary

Enum Constants

Enum Constant	Description
RETAIN_QUERY_EVIDENCE	When predictions are made on a variable with evidence, the prediction simply returns the evidence.
RETRACT_QUERY_EVIDENCE	When predictions are made on a variable with evidence, the variable's own evidence is ignored.

Method Summary

Modifier and Type	Method	Description
static QueryEvidenceMode	valueOf(String name)	Returns the enum constant of this type with the specified name.
static QueryEvidenceMode[]	values()	Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

RETAIN_QUERY_EVIDENCE

public static final QueryEvidenceMode RETAIN_QUERY_EVIDENCE

When predictions are made on a variable with evidence, the prediction simply returns the evidence.

RETRACT_QUERY_EVIDENCE

public static final QueryEvidenceMode RETRACT_QUERY_EVIDENCE

When predictions are made on a variable with evidence, the variable's own evidence is ignored. For example, consider a network with variables {A,B,C}, with evidence set on all variables. If you query {P(A),P(B),P(C)}, P(A) will only use the evidence on B and C, P(B) will only use the evidence on A and C, and P(C) will only use the evidence on A and B.

This allows the prediction of variables, without having to perform multiple calls to Inference.query(com.bayesserver.inference.QueryOptions, com.bayesserver.inference.QueryOutput), each time setting a different variable to null (missing).

Method Detail

values

public static QueryEvidenceMode[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (QueryEvidenceMode c : QueryEvidenceMode.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static QueryEvidenceMode valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
