Task-Oriented Multi-User Semantic Communications for VQA Task

Understand

Semantic communications focus on the transmission of semantic features.

• In this letter, we consider a task-oriented multi-user semantic communication system for multimodal data transmission.
• Particularly, partial users transmit images while the others transmit texts to inquiry the information about the images.
• To exploit the correlation among the multimodal data from multiple users, we propose a deep neural network enabled semantic communication system, named MU-DeepSC, to execute the visual question answering (VQA) task as an example.
