OpenSimula — 開源實現 Simula 風格機制設計用於合成資料（在 AfterImage 中）[P]

Hi r/MachineLearning, We added OpenSimula to our open-source dataset tool AfterImage: an experimental Python implementation of the Simula mechanism-design recipe from Davidson et al. (TMLR, PDF; framing also in this research blog). Problem it targets: For some SFT/eval setups you care less about “one prompt → one answer” and more about controlled diversity over a reasoning space: which axes of variation exist, how you joint-sample them, and how you stress-test generations before they land in
