World’s First Artificial Neuron: IBM’s Breakthrough Uses Phase-Change Material
IBM创造出世界上首个人造神经元
导读:IBM使用随机相面材料发明世界上首个人造神经元。
For computer scientists, creation of neuromorphic systems — those inspired by and modeled after the way neurons in the human brain are structured — has been a longstanding goal. 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.
对计算机科学家而言,建立神经形态体系一直是一个长期目标,该想法源于且模仿人类大脑中神经元的构成方式。如今对于神经形态技术的发展尤其重要, 在IBM位于苏黎世的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。
The invention, described in a paper published in the journal Nature Nanotechnology, consists of a small square of germanium antimony telluride held between two electrodes. Germanium antimony telluride, a common ingredient in optical disks, is what is known as phase-change material. This means it can change its phase from an amorphous insulator to a crystalline conductor when hit with a strong enough electric pulse — thus acting like both, a resister and capacitor, and mimicking, to a certain extent, the behavior of biological neurons’ lipid bilayer membrane.
此项发明在《自然纳米技术》杂志上发表,此发明由两个电极之间一小块锗锑碲构成。锗锑碲是制作光盘的常见材料,也就是所谓的相变材料。这便意味着当遇到足够强大的电子脉冲时,其能够从无定形态绝缘体转变为晶体态导体,因此它的工作原理既像是电阻器...
