Model Transfer with Explicit Knowledge of the Relation between Class Definitions

no code implementations CONLL 2018 Hiyori Yoshikawa, Tomoya Iwakura

Instead of learning the individual classification layers for the support and target schemes, the proposed method converts the class label of each example on the support scheme into a set of candidate class labels on the target scheme via the class correspondence table, and then uses the candidate labels to learn the classification layer for the target scheme.
