A cross-region transfer learning method for classification of community service cases with small datasets

作者:

Highlights:

• We seek to classify community service cases with small datasets in data imbalance situation.

• Existing transfer learning methods have high requirements both for the length and openness of case content.

• We use a cross-regional transfer learning to learn the map from local weak classes to non-local strong classes.

• Classifiers equipped with learned maps may use few samples for training.

• Both the cross-region semantic ambiguity and source domain feature representation are considered for effective classification.
