An anonymous reader quotes a report from Ars Technica: The fall of the Berlin Wall in November 1989 was a seminal moment in 20th century history, paving the way for German reunification. So [Francesco Armetta of the University of Palermo and co-authors of the paper] decided to adopt a machine-learning approach to enhance the precision and sensitivity of spectral data collected by those handheld devices. Armetta et al. also created their own mock-up samples by mixing commercial German acrylic paints (commonly used since the 1800s) in different ratios to try to match colors and tints from the fragments -- crucial information for restoration.
