# exp/10 sp5d-moment-features
|
||||||
|
|
||||||
|
Variant C: generic-only 19 + 16 new moment/volatility families (skew, kurt,
|
||||||
|
DSV+ratios, max_up/down, rv_ac1, rv_cv_22, sig lag-5). 35 sp_* fields, ou/hmm excluded.
|
||||||
|
|
||||||
|
Run a3f7d1d40c3d4b839314fcf5b40f9b08 (tac-rd-moments / exp 12) — FINISHED.

Same failure mode as ou/hmm in exp 9: adding cross-sectional moment features
|
||||||
|
to the 50-name panel degrades the rank signal. Generic-only 19 remains the
|
||||||
|
best configuration. No further moment-family variants planned.

# VARIANT C (generic + moments): keeps the winning generic-only 19-field set
|
||||||
|
# (jump,har,trend,hurst,signature) and adds the NEW generic moment families the
|
||||||
|
# engine now exposes:
|
||||||
|
# - realized skewness / kurtosis (sp_rskew_5, sp_rskew_22, sp_rkurt_5, sp_rkurt_22)
|
||||||
|
# - downside semi-variance + ratios (sp_dsv_1/5/22, sp_dsv_ratio_1/5/22)
|
||||||
|
# - signed max moves (sp_max_up, sp_max_down)
|
||||||
|
# - RV autocorr / vol-of-vol (sp_rv_ac1, sp_rv_cv_22)
|
||||||
|
# - longer-lag signature terms (sp_sig_level2_*_5)
|
||||||
|
# Drops the model-specific ou/hmm families (they scored high in importance but
|
||||||
|
# hurt the rank dimension in the all-24 run). Same panel/model as baseline.
