Two-dimensional subspace alignment for convolutional activations adaptation

作者:

Highlights:

• Two-dimensional subspace alignment (2DSA) is proposed for domain adaptation.

• The classification performance has low correlation to domain discrepancy measure.

• Local within- and between-class divergences are introduced to compare domains.

• A novel domain adaptation application in agriculture is illustrated.

• A MTFS3-DA dataset with 10 domains is developed for cross-field evaluation.
