世界上最小的類腦計算機

四川 蔣建平

世界上最小的類腦計算機問世了，它的能源消耗如此之小，以至于可以自己直接從周圍環(huán)境中獲取能量。

Artificial intelligence (AI) has seen explosive growth in recent years, but despite major progress, the power required to run AI algorithms（算法）continues to increase.In contrast to this,the human brain only requires around 20W to perform more than 10 quadrillions (10,000,000,000,000,000) operations, which is much better than modern supercomputer technologies.

“That's why we're conducting intensive research into developing new hardware that mimics the structure of the human brain,which is known as brain-inspired（類腦的）computing (BIC). But even though we've managed to largely reduce the energy consumption of AI algorithms, there's still a long way to go before BIC is as efficient as the human brain when it comes to size and energy efficiency,”says Hooman Farkhani,an assistant professor at Aarhus University.

He has just received support from the Villum Experiment program for a new project looking into the development of a nano-sized BIC system.“If we succeed, we'll have the first BIC system that is no larger than a grain of dust and with energy consumption that is so small that energy can be harvested directly from the surrounding environment,”says Hooman Farkhani. The project goes by the name of Spin-Grain, and is one of 51 projects that have just received the support from the Villum Experiment program under the Villum Foundation. The program donates money to“bold research experiments”and pays tribute to Villum Kann Rasmussen, the founder of the Villum Foundation, and his tireless experimental approach to life.

The researchers behind the 51 experiments range from PhD students to professors and represent a wide range of different nationalities. In addition to Aarhus University, grants（補助金）have been awarded to other universities like the University of Copenhagen, the Technical University of Denmark and the IT University.

Language Study

Ⅰ.Difficult sentence in the text

That's why we're conducting intensive research into developing new hardware that mimics the structure of the human brain, which is known as brain-inspired computing(BIC).這就是為什么我們正在進行深入的研究，開發(fā)模仿人腦結構的新硬件，這被稱為類腦計算（BIC）。

【點石成金】本句是一個主從復合句，句中的why we're conducting...是表語從句，that mimics the structure of the human brain 是限制性定語從句，關系代詞that在從句中作主語，which is known as...是非限制性定語從句，關系代詞which 代指新硬件模仿人腦結構這件事。
