Returns collection that contains factors in this model.

Give this CommandOption the opportunity to process the index'th argument in args. Return the next unprocessed index.

Get the cluster label for a particular instance.

Returns a textual representatio of the span, suitable for XML output, e.g.

Returns the pipe through which each added <code>Instance</code> is passed, which may be <code>null</code>.

Multiplies this potential by a constant such that it sums to 1. Destructive; returns this factor.

For each index i that is present in this vector, set this[i] += v[i]. If v has indices that are not present in this, these are just ignored.

Adds <tt>value</tt> to the list of things mapped to by key. @return The current list of values associated with key. (N.B. This deviates from Map

Shuffles the elements of this list among several smaller lists. @param proportions A list of numbers (not necessarily summing to 1) which, when normal

Get this element's priority. @return the priority

Returns the <code>Alphabet</code> mapping features of the data to integers.

Adds a scalar to every element in an array. @param m The array @param toadd The scalar

Returns an iterator over the assignments to this clique. Each element in the Iterator is an {@link cc.mallet.grmm.types.Assignment} object. @return A

Use a fifth order Stirling's approximation. @param z Note that Stirling's approximation is increasingly unstable as <code>z</code> approaches 0. If <

Runs inference across all the instances and returns the average token accuracy.

Does this = pot. <P> If both potentials are currently in log space, then does addition instead. @throws UnsupportedOperationException If one pote

Returns the factor in this graph, if any, whose domain is a given clique. @return The factor defined over this clique. Returns null if no such factor

Return the top element of the queue. @return top element of the queue

Returns the <code>Alphabet</code> mapping target output labels to integers.

Returns the weights for this clique template. Each possible assignment to the clique can in general have a different set of weights ,so this method

Returns <tt>Math.log(Math.exp(a) + Math.exp(b))</tt>. <p> <tt>a, b</tt> represent weights.

Multiplies every element in an array by a scalar. @param m The array @param factor The scalar

Returns the number of variable nodes in the graph.

Return the fraction of instances that have the correct label as their best predicted label.
