DeepStroke: An efficient stroke screening framework for emergency rooms with multimodal adversarial deep learning

•A powerful multimodal deep learning framework for stroke screening in ER settings•Spatiotemporal facial frame proposal tackles “in-the-wild” patient conditions•Multi-level fusion of visual and audio features achieves better overall performance•Adversarial training mitigates “face-remembering” and learns stroke features•Transfer learning reduces facial-attribute bias and improves generalizability
