SimplexTasks-12-data

Dataset-style artifact for the SimplexUQ benchmark.

Please cite: If you use SimplexUQ or SimplexTasks-12 in your research, please cite our paper: Liang You, Hengyu Shi, and Dongwen Ou. SimplexUQ: An Evaluation Framework and Benchmark for Conformal Uncertainty on Simplex-Valued Predictions, 2026.

Official repository

Authors: Liang You, Hengyu Shi, and Dongwen Ou.

This personal-account release is synchronized from the anonymous review artifact at revision a3c1f1f3975cecaae991e8dd256c2e66cd42adf6. The frozen data arrays are unchanged; this is a repository and metadata update, not a new experiment run. The source repository is anonymous0523ly/SimplexTasks-12-data. Archived result summaries retain their original experiment protocols; they are not a claim that every historical summary matches the final manuscript.

The repository retains the source artifact's license metadata. This does not override task-specific source terms or grant new rights to third-party assets; consult LICENSE, ASSET_PROVENANCE_AND_TERMS.md, and the task cards.

This bundle is artifact-first. Its primary contents are:

  • task_cards/ with one card per synthetic or real task
  • configs/ with method specs, benchmark task specs, and split policies
  • data/synthetic/ with frozen synthetic benchmark arrays
  • data/derived/ with frozen real-task derived arrays
  • data/summaries/ with metric summaries and figure/table inputs
  • data/viewer/tasks.jsonl as the flat table used by the Hugging Face Dataset Viewer
  • docs/ with provenance, restricted-asset notes, and reviewer quickstart

The benchmark is designed to run on frozen derived arrays and fixed predictor outputs. Restricted raw assets are intentionally excluded.

Important Release Rule

The benchmark consumes frozen (Y, U) arrays, task-specific strata metadata, and release notes for restricted assets. It is not a raw-data mirror.

Hugging Face Dataset Viewer

The viewer-facing dataset is intentionally limited to data/viewer/tasks.jsonl. This flat JSONL table summarizes the 12 task cards with a uniform schema. The other JSON, JSONL, CSV, and NumPy files in this repository are artifact inputs for reproduction and should not be mixed into the Dataset Viewer table.

Croissant-compatible tables

The data/parquet/ directory contains one lossless table for each of the 12 tasks. sample_index is the zero-based row index in the original frozen arrays. Columns U_0, U_1, ... and Y_0, Y_1, ... preserve the original component order. Synthetic tables additionally include R and sigma_true. Floating-point values and their stored precision are unchanged. The viewer split named train is a transport convention for a frozen sample pool, not a prescribed training split. Use the benchmark split policies for conformal evaluation.

See docs/parquet_verification.json for source-array hashes, table hashes and exact round-trip verification. These are format conversions, not new experiment runs. Croissant metadata is provided under croissant/.

License scope

The repository uses the other license category to match its existing artifact license notice and CITATION.cff. The notice and task-specific source terms govern reuse; there is no blanket CC-BY-4.0 grant for this collection. Format conversion does not change those terms. See LICENSE, ASSET_PROVENANCE_AND_TERMS.md and the individual task cards.
