One helpful tip per day:)

The article in Nature presents an intriguing story of applying machine learning to ancient text discovery:

  1. A student named Luke Farritor used a machine-learning algorithm to identify text within ancient scrolls found in the city of Herculaneum.
  2. The identified Greek word is πορφύρας, meaning "purple". This discovery is the first of its kind in such scrolls, indicating that more content might be deciphered in the future.
  3. Previously, a similar discovery was made in Israel where the ancient scroll contained metals, enabling imaging with CT scans. However, the carbonized scrolls from this recent find lacked metal, requiring the use of high-resolution X-ray imaging.

这篇 Nature 的报道相当精彩，讲述了一个将机器学习用于古文本发掘的故事：

  1. 一位名叫 Luke Farritor 的学生使用机器学习算法，识别了 Herculaneum 古城中遗留的古卷中的文字；
  2. 识别出来的希腊语单词是 πορφύρας，意即紫色，这个单词是第一次在这类古卷中被识别出来，意味着更多的内容将被破解；
  3. 类似的发现之前曾在以色利出现，当时的古卷里富含金属，所以用 CT 就能造影；而这回的碳化古卷里不含金属，所以只能用高精度的 X 光造影。
