Returns whether the potential is over the given variable.

VECTOR OPERATIONS

Returns the label index mapped to the state index. @param stateIndex State index. @return Index of the label that is mapped to the state. Returns <tt

Increments this[index] by value. @throws IllegalArgumentException If index is not present.

Returns the sum of two doubles expressed in log space, that is, <pre> sumLogProb = log (e^a + e^b) = log e^a(1 + e^(b-a))

Returns set of variables in this potential.

Assumes that the CRF's output alphabet contains <code>String</code>s. Creates an order-<em>n</em> CRF with input predicates and output labels given by

Returns an iterator over all Assignmentss to this potential.

This method should be called by subclasses whenever evaluators should be run. Do not worry too much about them being run too often, because the evalua

Returns a collection of all factors that involve only the given variables. That is, all factors whose domain is a subset of the given collection.

This method should be called whenever the CRFs weights (parameters) have their structure/arity/number changed.

Classify an instance using NaiveBayes according to the trained data. The alphabet of the featureVector of the instance must match the alphabe of the p

Dumps all the variables and factors of the model to <tt>System.out</tt> in human-readable text.

Calculate the F1-measure of the classifier on an instance list for a particular target entry

Returns an integer index identifying the start of this span. Beware that in some cases (e.g., for images), this may not correspond directly to a s

Return a random double drawn from a Gamma distribution with mean 1.0 and variance 1.0.

Only sets the parameter from the first group of parameters.

Returns the union of two Assignments. That is, the value of a variable in the returned Assignment will be as specified in one of the given assignmen
