- New Aenebris.ML.Inference module: pure tree-walk over the unified Tree SoA produced by Aenebris.ML.Loader. Mirrors LightGBM C++ NumericalDecision exactly: NaN remapped to 0 unless MissingType=NaN; MissingType=Zero/NaN routes via default-left flag; '<=' predicate (not '<'); categorical bitmap test using cat_boundaries slice; average_output divisor for RF mode; sigmoid link for binary logistic objective. kZeroThreshold = 1e-35 matches LightGBM's IsZero exactly. Defensive against NaN/Inf/negative on categorical paths. 35 tests covering leaf-only, numerical splits, missing-value semantics, categorical routing, multi-tree sums, sigmoid saturation, average_output, regression vs binary objectives, and end-to-end against the disk fixture. - New Aenebris.ML.Calibration module: pure calibration of binary classifier outputs. Calibrator ADT (NoCalibrator | PlattCalibrator a b | IsotonicCalibrator bp). Platt scaling uses Newton's method with damped line search on Platt-1999 smoothed targets (N+ + 1)/(N+ + 2) and 1/(N- + 2); numerically stable softplus-based log-loss. Isotonic regression uses Pool Adjacent Violators on a stack with tie pre- grouping, sorted (raw, calibrated) breakpoints, linear interpolation, out-of-range clamping. Sub-2-sample input returns NoCalibrator. 28 tests covering all three calibrator constructors, fit edge cases, Platt convergence on logistic data, isotonic correction of non- monotone data, tie handling, all-same-label degenerate cases, and lookup behavior including clamping and interpolation. - aenebris.cabal: expose both new modules in the library stanza. - 301 total examples passing, 0 GHC warnings on either new module. |
