A team of scientists has developed an algorithm that captures our learning abilities, enabling computers to recognize and draw simple visual concepts that are mostly indistinguishable from those created by humans. The work, which appears in the latest issue of the journal Science, marks a significant advance in the field -- one that dramatically shortens the time it takes computers to 'learn' new concepts and broadens their application to more creative tasks. "Our results show that by reverse engineering how people think about a problem, we can develop better algorithms," explains Brenden Lake, a Moore-Sloan Data Science Fellow at New York University and the paper's lead author. "Moreover, this work points to promising methods to narrow the gap for other machine learning tasks."
➧ promising --adj.有希望的,有前途的
參考例句:
The results of the experiments are very promising.
 實驗的結果充滿了希望。
We're trying to bring along one or two promising young swimmers.
 我們正設法培養出一兩名有前途的年輕游泳選手。
  
The paper's other authors were Ruslan Salakhutdinov, an assistant professor of Computer Science at the University of Toronto, and Joshua Tenenbaum, a professor at MIT in the Department of Brain and Cognitive Sciences and the Center for Brains, Minds and Machines.
➧ cognitive --adj.認知的,認識的,有感知的
參考例句:
As children grow older, their cognitive processes become sharper.
 孩子們越長越大,他們的認知過程變得更為敏銳。
The cognitive psychologist is like the tinker who wants to know how a clock works.
 認知心理學者倒很像一個需要通曉鐘錶如何運轉的鐘錶修理匠。
  
When humans are exposed to a new concept -- such as new piece of kitchen equipment, a new dance move, or a new letter in an unfamiliar alphabet -- they often need only a few examples to understand its make-up and recognize new instances. While machines can now replicate some pattern-recognition tasks previously done only by humans -- ATMs reading the numbers written on a check, for instance -- machines typically need to be given hundreds or thousands of examples to perform with similar accuracy.
➧ unfamiliar --adj.陌生的,不熟悉的
參考例句:
I am unfamiliar with the place and the people here.
 我在這兒人地生疏。
The man seemed unfamiliar to me.
 這人很面生。
➧ replicate --v.折疊,複製,模寫;n.同樣的樣品;adj.轉折的
參考例句:
The DNA of chromatin must replicate before cell division.
 染色質DNA在細胞分裂之前必須複製。
It is also easy to replicate, as the next subsection explains.
 就像下一個小節詳細說明的那樣,它還可以被輕易的複製。
➧ previously --adv.以前,先前(地)
參考例句:
The bicycle tire blew out at a previously damaged point.
 自行車胎在以前損壞過的地方又爆開了。
Let me digress for a moment and explain what had happened previously.
 讓我岔開一會兒,解釋原先發生了什麼。
  
"It has been very difficult to build machines that require as little data as humans when learning a new concept," observes Salakhutdinov. "Replicating these abilities is an exciting area of research connecting machine learning, statistics, computer vision, and cognitive science."
➧ replicating--複製( replicate的現在分詞 ); 重複; 再造; 再生
參考例句:
Applications create these partitions for storing and replicating data. 
 應用程式創建這些分區用來儲存和複製資料。
The closest real things to these creatures were bits of self-replicating RNA. 
 最貼近這些造物的實物是能做一點微不足道的自複製的核糖核酸。
