A new research project of Japan can analyze2 a persons brain scans3 and provide a written description of what they have been looking at.
日本一個新型研究項目能夠分析人類大腦的掃描結果,并得出一份書面報告,描述了人們看到的東西。
When a person is looking at a picture, the artificial intelligence is given an fMRI brain scan image. It then produces a written de-scription of what they think the person was viewing. It can offer a description like: “A dog is sitting on the floor in front of an open door.” or “A group of people standing on the beach.” Both of those turn out to be quite accurate4.
當受試者看一張圖片時,人工智能就接受來自功能性磁共振成像得來的腦部掃描圖像。緊接著它輸出一份關于人們認為受試者正看見的東西的書面描述。這個人工智能得出的書面描述精準程度如下:“一只狗坐在敞開著的門前的地板上”或者“一群人站在沙灘上”。經確認,這兩個描述都十分精準。
“Our goal is to understand how the brain represents5 information about the real world,” Ichiro Kobayashi, one of the researchers from Japans Ochanomizu University, told Digital Trends. “Toward such a goal, we showed that our algorithm6 can model and read out perceptual7 contents from human brain activity. And the algorithm do this in the form of sentences. So we modified8 an existing network model. It could generate sentences from images.
小林一郎是來日本御茶水女子大學的研究人員之一。他向《電子趨勢》透露:“我們的目標是了解大腦是怎樣呈現現實世界傳遞給它的信息的。設定這個目標之后,通過演示,我們的(計算機)算法能夠以句子的形式模擬并讀出大腦活動中的感知內容。所以我們對一個現有的網絡模型作出修改。它(模型)能夠用句子的形式呈現從圖像中讀到的內容。”
However, Kobayashi points out that it still a long way away from real-world application9. “So far, there are not any real-world applica-tions for this,” Kobayashi continued. “Howev-er, in the future, it might be used widely.”
然而,小林一郎指出,要將這個模型運用到現實中還需要做很多工作。他說:“目前該模型還無法進行實際運用。然而,將來這種技術可能會被廣泛使用。”
As a next step, Shinji Nishimoto, another researcher on the project, told Digital Trends that the team wants to use it to better under-stand how the brain processes10 information.
西本真治作為該項目的另一位研究人員向《電子趨勢》透露,研究組下一步要利用這個技術更進一步了解大腦是怎樣加工信息的。
“We would like to understand how the brain works under naturalistic11 conditions,” Nishimoto said. “Toward such a goal, we are planning to find out how various forms of in-formation—vision12, languages, impressions, etc.—are encoded13 in the brain. In particular, we will work on generating descriptions about what a person thinks.”
“我們想要了解大腦在自然條件下是怎么運作的。因此,我們計劃深入研究各種信息(視覺、語言、印象等等)在大腦中是怎樣加工的。我們特別致力于這個技術(以句子形式)對人類大腦中所想的書面描寫。”
