摘要:

我们考虑在无线边缘的分布式推理,其中多个客户端具有一组模型,每个模型都在本地数据集上独立训练,并行查询以对新样本做出准确的决策。除了最大限度地提高推理准确性外,我们还希望最大限度地提高局部模型的隐私性。我们利用空气的叠加特性来实现带宽有效的集成推理方法。我们介绍了不同的空中集成方法,并表明这些方案的性能显着优于正交同行,同时使用更少的资源,并提供隐私保证。我们还提供了实验结果,验证了所提出的空中推理方法的好处,其源代码在Github上公开共享。

英文摘要:

We consider distributed inference at the wireless edge, where multiple clients with an ensemble of models, each trained independently on a local dataset, are queried in parallel to make an accurate decision on a new sample. In addition to maximizing inference accuracy, we also want to maximize the privacy of local models. We exploit the superposition property of the air to implement bandwidth-efficient ensemble inference methods. We introduce different over-the-air ensemble methods and show that these schemes perform significantly better than their orthogonal counterparts, while using less resources and providing privacy guarantees. We also provide experimental results verifying the benefits of the proposed over-the-air inference approach, whose source code is shared publicly on Github.
