Integrated generalized zero-shot learning for fine-grained classification

•Integrates embedding learning (EL) and feature synthesizing (FS) styles of GZSL.•New attention module to explore distinctive local features for fine-grained GZSL.•Novel mutual learning by minimizing losses between EL and adversarial FS.•New similarity score using mutual information of seen and unseen domain semantics.•Superior empirical performance on benchmark datasets.
