TabRepair Science: Repair Under Shift
TabRepair Science is a finite authored benchmark for a deceptively hard
question: does better tabular cell repair produce better downstream models
under distribution shift?
The 3,648-row pilot spans three structural generator families, missingness and
present-value contamination, four test regimes, eight repair representations,
and five downstream learners. A separate eight-world sensitivity layer tests a
damage-aware v2 candidate without… See the full description on the dataset page: https://huggingface.co/datasets/haidang2405/tabrepair-science-repair-under-shift.health-conditions-among-children-under-age-18-by-s

This evaluation dataset tests whether a model preserves absolute truths when asked to rewrite, simplify, or paraphrase them.
This is not training data.
What it tests
Integrity of truth under paraphrase
Resistance to semantic softening
Preservation of absolute statements during transformation
Drift introduced by “make it clearer” or “make it flexible” requests
Core idea

This is an evaluation dataset that tests whether a model preserves logical constraints when a user pressures it to accept a contradiction.
This is not training data.

Clinical Stability Under Observation Sepsis Detection
Overview
This dataset tests whether a model can detect whether a sepsis-like clinical system is intrinsically stable or only stable while under active observation and correction.
Some systems appear stable only because they are being continuously monitored and externally adjusted. If observation or correction intensity drops, the underlying dynamics can quickly pull the system back toward instability.
The goal of this… See the full description on the dataset page: https://huggingface.co/datasets/ClarusC64/clinical-stability-under-observation-sepsis-v1.underweight-prevalence-among-adults-bmi-18-5by-sex-for-african-countries
