We propose a joint transmission-recognition scheme for efficient inference at the wireless network edge. Our scheme allows for reliable image recognition over wireless channels with significant computational load reduction at the sender side. We incorporate recently proposed deep joint source-channel coding (JSCC) scheme, and combine it with novel filter pruning strategies aimed at reducing the redundant complexity from neural networks. We evaluate our approach on a classification task, and show satisfactory results in both transmission reliability and workload reduction. This is the first work that combines deep JSCC with network pruning and applies it to images classification over wireless network.
