If you're a fan of the Beatles, you no doubt know that "She Loves You" came before "All You Need Is Love". But what about "Help!" or "Yellow Submarine" or "I am the Walrus"?
如果你喜歡甲殼蟲樂隊，不用說，你肯定知道歌曲《她愛你》的創作先于《你需要的只是愛》。那么你對《救命！》、《黃色潛水艇》、或者《我是海象》又了解多少？
You may not know which came first, but researchers from Lawrence Technological University in Michigan created an algorithm that does. By analyzing the evolving structure of the Beatles'music, the computer program was able to correctly place the Fab Four's albums in chronological order. The work is in the journal Pattern Recognition Letters.
你也許不知道最先創作的是哪首歌，但有種算法就能做到，該算法是美國密歇根勞倫斯理工大學的研究人員發明的。通過對甲殼蟲樂隊所創歌曲的發展結構進行分析，該計算機程序能夠準確地將其所創專輯按時間順序排列。該研究發表在《模式識別快報》中。
The researchers initially produced the algorithm to catalogue whale songs. And they figured what worked for killer whales should also work for the lads from Liverpool.
最初，該算法是用來編目《鯨之歌》的。當研究人員發現這方法行之有效時，他們認為該算法對甲殼蟲樂隊的歌曲肯定也行得通。
The program converts audio data into a visual spectrogram, and image it then evaluates for texture, shape, and pattern. Based on this analysis, the algorithm could tell that "Please Please Me" was from the early days and "She Came In through the Bathroom Window" came near the end. It even correctly estimated that songs from Let It Be were recorded before those onAbbey Road, although Abbey Road was released first.
該程序能將音頻數據轉化為視覺光譜圖，并合成圖像，然后對其紋理、形狀、模式進行評估。根據這一分析，該算法可分辨出《請取悅我》是甲殼蟲樂隊的早期作品，而《她通過浴室的窗戶進來》是他們的晚期作品。它甚至能辨認出歌曲《順其自然》的錄制先于《艾比路》，盡管《艾比路》的發行早于《順其自然》。
The algorithm also worked for the albums of Queen, U2, and ABBA. But the computer came up short on Taylor Swift, whose tunes thus far are too similar to sort. Of course, her style could still change over time.
該算法也適用于皇后樂隊、U2樂隊和阿巴合唱團所創的專輯。但對泰勒•斯威夫特所創專輯卻束手無策，因為她的曲調太相似了。除非她的風格隨著時間的改變而改變。
