The insight library

Every night a deterministic miner tests every feature against every target it is allowed to touch, with as-of joins, false-discovery control and a time-ordered holdout. Survivors land here, graded; failures stay, labelled. How it works

promising 7weak 13baseline_onlybaseline_only A game insight that predicts the result (who wins, by how much) rather than the result against the betting line. Real, but the line already prices it, so it is not an edge. glossary = predicts the result, not the result against the line what the grades meanGrade robust: significant after correction, out of sample, costs, stable, holdout agrees. promising: significant with out-of-sample excess, holdout not decisive. weak: screened but failed out of sample or the holdout. failed: was promising, no longer. Retired rows stay visible. glossary
