Example of a core and removed flakes from the input dataset. (a) The training dataset consists of pairs of flaked cores (blue) and their matching flakes removals (red), oriented such that together they represent the complete core prior to flaking, much like a refit. (b) Some of the flake and core pairs were generated in different stages of reduction (see “Methods”). This is an illustration of a generated reduction sequence. Note that, in the dataset, each flake has a matching modified core model as well.
