Inference

trait Inference[Datum] extends Serializable

Inference is the core interface in Epic. It produces instances of epic.framework.Marginal which are then turned into epic.framework.ExpectedCounts.

There are two kinds of marginals produced by an inference object: gold and guess. Gold marginals are the marginals conditioned on the output label/structure itself (e.g. the parse tree). Guess marginals are the marginals conditioned on only the input data (e.g. the words in the sentence)

In structured prediction, the objective usually takes the form: \minimize \sum_{all structures} score(structure) - \sum_{all structures compatible with output label} score(structure)

with the derivative being: E_{all structures} features(structure) - E_{all structures compatible with output label} features(structure)

replacing sum with max for max marginals.
