Mikolaj Jankowski, Deniz Gunduz, Krystian Mikolajczyk

TL;DR
AirNet introduces a novel approach for efficiently transmitting deep neural networks over wireless channels by directly mapping network parameters to channel symbols, optimizing for accuracy under power and latency constraints.
Contribution
The paper presents a new joint source-channel coding method for DNN transmission, including training strategies for robustness, pruning, expansion, and multi-condition training.
Findings
AirNet outperforms separation-based methods in accuracy.
Pruning and expansion improve robustness and bandwidth utilization.
Training multiple DNNs for different conditions reduces memory requirements.
Abstract
State-of-the-art performance for many edge applications is achieved by deep neural networks (DNNs). Often, these DNNs are location- and time-sensitive, and must be delivered over a wireless channel rapidly and efficiently. In this paper, we introduce AirNet, a family of novel training and transmission methods that allow DNNs to be efficiently delivered over wireless channels under stringent transmit power and latency constraints. This corresponds to a new class of joint source-channel coding problems, aimed at delivering DNNs with the goal of maximizing their accuracy at the receiver, rather than recovering them with high fidelity. In AirNet, we propose the direct mapping of the DNN parameters to transmitted channel symbols, while the network is trained to meet the channel constraints, and exhibit robustness against channel noise. AirNet achieves higher accuracy compared to…
