A two-stage reconstruction-based OSR–ZSD framework for generalized zero-shot fault diagnosis in industrial processes

In industrial processes, some fault types lack sufficient training data, and test samples may originate from both seen and unseen classes, giving rise to a generalized zero-shot diagnosis (GZSD) scenario. Existing methods often suffer from severe class bias, incorrectly classifying unseen faults as seen ones and thus c...
