A novel image analysis using convolutional neural networks in a one-shot learning architecture with a triplet loss function is used to develop a range of \u2018distances\u2019 to known \u2018reference\u2019 images for a group of skulls with known provenances and a group of images of skulls from social media posts. Comparing the two groups enables us to predict a broad geographic \u2018ancestry\u2019 for any given skull depicted, using a mixture discriminant analysis, as well as a machine-learning model, on the image dissimilarity scores. It thus seems possible to assign, in broad strokes, that a particular skull has a particular geographic ancestry.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>History Professor Shawn Graham, along with three of his colleagues, have published a paper in the Journal of Computer Applications in Archaeology (CAA).
