Base class for discrete probabilistic factors The most general one is the derived DecisionTreeFactor.
DecisionTreeFactor, which represent a discrete distribution over a set of variables.
|
|
| DiscreteFactor () |
| Default constructor creates empty factor.
|
|
template<typename CONTAINER > |
| DiscreteFactor (const CONTAINER &keys) |
| Construct from container of keys.
|
|
virtual | ~DiscreteFactor () |
| Virtual destructor.
|
|
|
virtual bool | equals (const DiscreteFactor &lf, double tol=1e-9) const =0 |
| equals
|
|
void | print (const std::string &s="DiscreteFactor\n", const KeyFormatter &formatter=DefaultKeyFormatter) const override |
| print
|
|
|
virtual double | operator() (const DiscreteValues &) const =0 |
| Find value for given assignment of values to variables.
|
|
double | error (const DiscreteValues &values) const |
| Error is just -log(value)
|
|
double | error (const HybridValues &c) const override |
| All factor types need to implement an error function.
|
|
virtual DecisionTreeFactor | operator* (const DecisionTreeFactor &) const =0 |
| Multiply in a DecisionTreeFactor and return the result as DecisionTreeFactor.
|
|
virtual DecisionTreeFactor | toDecisionTreeFactor () const =0 |
|
virtual | ~Factor ()=default |
| Default destructor.
|
|
bool | empty () const |
| Whether the factor is empty (involves zero variables).
|
|
Key | front () const |
| First key.
|
|
Key | back () const |
| Last key.
|
|
const_iterator | find (Key key) const |
| find
|
|
const KeyVector & | keys () const |
| Access the factor's involved variable keys.
|
|
const_iterator | begin () const |
| Iterator at beginning of involved variable keys.
|
|
const_iterator | end () const |
| Iterator at end of involved variable keys.
|
|
size_t | size () const |
|
virtual void | printKeys (const std::string &s="Factor", const KeyFormatter &formatter=DefaultKeyFormatter) const |
| print only keys
|
|
bool | equals (const This &other, double tol=1e-9) const |
| check equality

|
KeyVector & | keys () |
|
iterator | begin () |
| Iterator at beginning of involved variable keys.
|
|
iterator | end () |
| Iterator at end of involved variable keys.
|
|
|

template<typename CONTAINER > |
static Factor | FromKeys (const CONTAINER &keys) |
| Construct factor from container of keys.
|
|
template<typename ITERATOR > |
