Pre-registration: certifying offline evaluation lenses from gold users on KuaiRec (confirmatory half)

Year: 2026

Type: preprint

Abstract: Pre-registration of the confirmatory analysis for a study of offline evaluation of recommender systems under sparse, partially randomized logs. It fixes five hypotheses (HC1 to HC5), their thresholds, the analysis procedure and seed before the confirmatory half of the KuaiRec 2.0 dense users is read. The SHA-256 lists fix the analysis code and the user split.
