Figure

Figure 1: La-DTL framework overview: embeddingand Bi-LSTM layers are shared across domains, predic-tors in red (upper) boxes are task-specific CRFs, withlabel-aware MMD and L2 constraints to perform fea-ture representation transfer and parameter transfer.
Figure 2: Illustration for La-MMD. MMD-yputed between two domains’ hidden representationswith the same ground truth labelnation is then applied to each label-wise MMD to formLa-MMD and the coefficient is set as is com- y
