Detailed Description
The Continuous chance node.
This node represents continuous chance nodes with (conditional) Gaussian distributions. Continuous chance nodes are also sometimes called CG nodes (CG for conditional Gaussian).
Member Function Documentation
| bool HAPI::ContinuousChanceNode::caseIsSet | ( | size_t | index | ) | const |
Test whether the value of this node in case index currently is set.
- Parameters:
-
index Case index.
| ContinuousChanceNode* HAPI::ContinuousChanceNode::clone | ( | ) | const [virtual] |
Clone this ContinuousChanceNode object.
Implements HAPI::Node.
| void HAPI::ContinuousChanceNode::enterValue | ( | double | value | ) |
Specify that this continuous node has the value value.
- Parameters:
-
value A real number as the finding value.
| double HAPI::ContinuousChanceNode::getCaseValue | ( | size_t | index | ) | const |
Retrieve the value of this node assoociated with case index.
- Parameters:
-
index Case index.
| Category HAPI::ContinuousChanceNode::getCategory | ( | ) | const [inline, virtual] |
| CGDistribution* HAPI::ContinuousChanceNode::getCGDistribution | ( | ) |
Get the CG distribution associated with this node.
- Returns:
- CGDistribution*
| Table* HAPI::ContinuousChanceNode::getDistribution | ( | ) | const |
Compute the distribution for this continuous node.
The distribution for a CG node is in general a mixture of several Gaussian distributions. ContinuousChanceNode::getDistribution () really computes a joint distribution of this node and a set of discrete nodes. These discrete nodes are chosen such that the computed marginal is a strong marginal, but it is not necessarily minimal.
- Returns:
- Table* pointer to a Table holding a strong marginal of this node and a set of discrete nodes.
| double HAPI::ContinuousChanceNode::getEnteredValue | ( | ) | const |
Retrieve the entered value for this node.
- Returns:
- A double-precision real number expressing the entered value.
| Kind HAPI::ContinuousChanceNode::getKind | ( | ) | const [inline, virtual] |
| double HAPI::ContinuousChanceNode::getMean | ( | ) | const |
Return the mean of the marginal distribution of this node.
- Returns:
- A double-precision real number expressing the mean.
| double HAPI::ContinuousChanceNode::getPropagatedValue | ( | ) | const |
Retrieve the finding value.
That is, retrieve the finding value incorporated within the current junction tree potentials for state of this node.
- Returns:
- A double-precision real number expressing the propagated value.
| double HAPI::ContinuousChanceNode::getSampledValue | ( | ) | const |
Returns the value of this ContinuousChanceNode for the configuration generated by the most recent call to Domain.simulate().
- Returns:
- The value sampled for this node during the last invocation of simulate () on the Domain of this node.
- See also:
- Domain::simulate
| double HAPI::ContinuousChanceNode::getVariance | ( | ) | const |
Return the variance of the marginal distribution of this node.
- Returns:
- A double-precision real number expressing the variance.
| bool HAPI::ContinuousChanceNode::isEvidenceEntered | ( | ) | const |
Return whether or not evidence is entered into this node.
- Returns:
- Boolean.
| bool HAPI::ContinuousChanceNode::isEvidencePropagated | ( | ) | const |
Return whether or not evidence has been propagated from this node.
- Returns:
- Boolean.
