concept:decontamination
Decontamination
Decontamination in the context of production machine-learning systems.
Lessons
Formal explanations, examples, simulations, and checkpoints.
Foundation-model lifecycle
Pretraining objectives, scaling, and checkpoints
Pretraining progress is tokens transformed into validated capability, backed by slice-aware loss and checkpoints that preserve the exact continuation state.
Foundation-model lifecycleSFT, preference optimization, safety, and tools
Post-training aligns behavior only to the examples and constraints you encode; tool permissions and safety must still be enforced and evaluated outside the loss.
Foundation-model lifecycleEvals, model cards, feedback, and reproducibility
Reliable releases bind artifacts, predeclared eval gates, honest limitations, and bias-aware feedback into one reproducible decision record.
Courses & assignments
Dependency-authoritative learning units.
Casebook
Reported facts and course reconstructions.
