Biological fundamentals and recent progress of artificial sensory neurons are systematically *** device, performance metrics, and potential applications of artificial sensory neurons are *** for the future development of artificial sensory neurons are discussed. Spike-based neural networks, which use spikes or action potentials to represent information, have gained a lot of attention because of their high energy efficiency and low power consumption. To fully leverage its advantages, converting the external analog signals to spikes is an essential prerequisite. Conventional approaches including analog-to-digital converters or ring oscillators, and sensors suffer from high power and area costs. Recent efforts are devoted to constructing artificial sensory neurons based on emerging devices inspired by the biological sensory system. They can simultaneously perform sensing and spike conversion, overcoming the deficiencies of traditional sensory systems. This review summarizes and benchmarks the recent progress of artificial sensory neurons. It starts with the presentation of various mechanisms of biological signal transduction, followed by the systematic introduction of the emerging devices employed for artificial sensory neurons. Furthermore, the implementations with different perceptual capabilities are briefly outlined and the key metrics and potential applications are also provided. Finally, we highlight the challenges and perspectives for the future development of artificial sensory neurons.

通过对系统进行对抗攻击可以检测系统漏洞，进而提高系统鲁棒性。然而，对抗攻击前往往需要系统的参数信息，这使得攻击条件受限。为此，结合一种新的量子粒子群优化算法，提出一种黑盒有目标对抗攻击方法。该方法通过在原始样本中添加微小噪声，构造差异化粒子群，作为初始对抗样本种群；基于记忆搜索的领域重分布策略得到当前种群的全局最优粒子，从而生成初始对抗样本；融入扩维和自适应权重位置更新，使得种群更接近目标；根据对抗样本与目标语句的编辑距离，继续优化初始对抗样本，生成最终对抗样本。为了验证方法的攻击效果，在GoogleSpeech、LibriSpeech以及CommonVoice数据集上，对语音识别模型DeepSpeech进行实验，将目标语句设置为不同场景中的常见语音指令。实验结果表明，提出的方法在三个数据集上成功率都优于对比方法，其中在Common Voice数据集上的成功率比对比方法提升了10个百分点。同时，召集志愿者对生成的对抗样本噪声强度进行主观评估，其中82.4%的对抗样本被志愿者判断为没有噪声或噪声很小。
