谷歌的AI技術竟能預測病人何時會死？

AI knows when you're going to die. But unlike in sci-fi movies, that information could end up saving lives.

人工智能知道你的死亡時間。但和科幻電影不同的是，這些信息最后可能會挽救生命。

A new paper published in Nature suggests that feeding electronic health record data to a deep learning model could substantially improve the accuracy of projected outcomes.

一篇發(fā)表在《自然》雜志上的新論文顯示，深度學習模型的進食電子健康數(shù)據(jù)能夠大幅提高預測結(jié)果的準確性。

In trials using data from two US hospitals, researchers were able to show that these algorithms could predict a patient's length of stay and time of discharge, but also the time of death.

在使用了兩家美國醫(yī)院數(shù)據(jù)的試驗中，研究人員可以證明這些算法不僅能夠預測病人的住院天數(shù)和出院時間，還能預測死亡時間。

The neural network described in the study uses an immense amount of data, such as a patient's vitals and medical history, to make its predictions.

研究中所描述的神經(jīng)網(wǎng)絡使用了大量的數(shù)據(jù)進行預測，比如病人的生命特征和病史。

A new algorithm lines up previous events of each patient's records into a timeline, which allowed the deep learning model to pinpoint future outcomes, including time of death.

一種新的算法將每個病人所記錄的活動經(jīng)歷排列成一個時間軸，這使得深度學習模型能夠確定包括死亡時間在內(nèi)的未來的結(jié)果。

The neural network even includes handwritten notes, comments, and scribbles on old charts to make its predictions. And all of these calculations are done in record time, of course.

用于預測的神經(jīng)網(wǎng)絡甚至包括在舊圖表上手寫的筆記、評論和涂鴉。當然，所有的這些計算都是在記錄時間內(nèi)完成的。

What can we do with this information, besides fear the inevitable? Hospitals could find new ways to prioritize patient care, adjust treatment plans, and catch medical emergencies before they even occur.

除了害怕這些不可避免的事情，我們還能用這些信息做什么?醫(yī)院可以找到新的方法來優(yōu)先照顧病人，調(diào)整治療方案，并在發(fā)生緊急情況之前及時處理醫(yī)療事故。

It could also free up healthcare workers, who would no longer have to manipulate the data into a standardized, legible format.

它也可以解放醫(yī)療工作者，他們不再需要將數(shù)據(jù)轉(zhuǎn)換成標準化的、更易讀取的格式。
