Unlock: FSRS: Spaced-Repetition Scheduling as Parameter Estimation
FSRS models memory as a difficulty-stability-retrievability (DSR) triple with a power-law forgetting curve, fits its weights by maximum-likelihood optimization over real review logs, and beats SM-2 on held-out calibration benchmarks. What TheoremPath's own scheduler does, and does not, implement.
