人造神经元

如今，作为关于神经形态技术的发展尤的重要一步，位于苏黎世的IBM实验室中，一组研究人员宣布他们已经发明了一个正在运行的人造神经元。

Now , in a significant step toward the development of neuromorphic technologies , a group of researchers IBM 's research laboratory in Zurich have announced that they have built a working , artificial version of a neuron .

那么为什么人造神经元具有随机特性，使得系统输出本身具有不可预测性？

So why is this stochasticity - which makes the output of a system inherently unpredictable - desirable in an artificial neuron ?

由于细胞内部的波动，生物神经元是随机的，诸如离子导电的变化、热背底的变化，而人造神经元也表现出了随机特性，因为锗锑碲的无定形态在每次复位后都有轻微的变化。

Biological neurons are stochastic due to fluctuations within the cell - such as changes in ionic conductance and thermal background - while these artificial neurons are stochastic because the amorphous state of germanium antimony telluride always changes slightly after each reset .
