摘要:

深度神经网络具有令人印象深刻的分类性能,但这是以推理时大量计算资源为代价的。自主式水下机器人使用低功耗的嵌入式系统进行声纳图像感知,无法实时的【形】执行大型神经网络。我们建议积极使用最大池,我们证明了它与基于火的模块和一个新的微小的模块,包括最大池在每个模块。通过堆叠它们,我们构建的网络可以达到与较大网络相同的精度,同时减少参数数量并大大提高计算性能。我们的网络可以在Raspberry Pi 2上以98.8 - 99.7的精度对96 x96的声纳图像进行分类,仅需41至61毫秒,这相当于28.6 - 19.7的加速比。

英文摘要:

Deep Neural Networks have impressive classification performance, but this comes at the expense of significant computational resources at inference time. Autonomous Underwater Vehicles use low-power embedded systems for sonar image perception, and cannot execute large neural networks in real-time. We propose the use of max-pooling aggressively, and we demonstrate it with a Fire-based module and a new Tiny module that includes max-pooling in each module. By stacking them we build networks that achieve the same accuracy as bigger ones, while reducing the number of parameters and considerably increasing computational performance. Our networks can classify a 96x96 sonar image with 98.8 - 99.7 accuracy on only 41 to 61 milliseconds on a Raspberry Pi 2, which corresponds to speedups of 28.6 - 19.7.
