Run a focused checkpoint.
Answer what you know, skip what you do not, and let the run turn weak signals into a short review path.
Scope
Run at a glance
Starts with lower-friction anchors, then checks the concentration-to-learning-theory bridge.
Focused checkpoint
Ready for the checkpoint run?
Answer what you know and skip what you do not. Misses adjust the remaining order, and the result becomes a short review path for this checkpoint.
Probability / concentration foundations
A curated 10-question diagnostic spine for probability measures, moments, Markov, union bounds, and continuity of probability.
Learner can read basic probability-measure arguments and recognize when Markov, union-bound, or continuity assumptions are being used.
How this run adapts
Review focus
- event algebra
- probability-measure assumptions
- finite versus countable additivity
- tail-bound setup
Could unlock
- Event Risk Calculator
- Union Bound Sanity Checker
Optional self-check
Leave blank if you want the neutral ramp. Pick only the areas where you have a strong signal.
Vectors, matrices, derivatives, notation.
Distributions, estimators, likelihood, concentration.
Gradients, convexity, SGD, Adam, proximal ideas.
ERM, VC, PAC, Rademacher, generalization.
Deep nets, attention, transformers, value functions.
Moving ideas across topics and checking assumptions.

Browser-only run
This diagnostic will save for this browser, but it will not create account-level learning events. Sign in first if you want the run to count toward your profile.
