check-out “model extraction attacks”
The search results I’m seeing for that term point to people extracting (a clone of) the model, through interacting with the available API of an otherwise closed model. I’m not really seeing anyone interacting with a model to extract its training input data.
Is there a better search term, or do you have a more direct reference to lossless extraction of training data from model weights?









Probably yes. Dionysius Exiguus invented numbering years since the supposed birth of Christ, instead of counted by era of Roman consuls. So by 1066 the practice would have been common throughout Christian Europe. The only doubts I have are around the introduction of the Gregorian Calendar later, and whether the 14 October 1066 would be counted as the 14 October 1066 in their system. But I think the year would be right.
