ExoMiner++ TESS 2-min TCEs (Hugging Face format)

The ExoMiner++ dataset of TESS SPOC 2-min TCEs, sectors 1-67, converted from the original TFRecords to Hugging Face datasets.

• Paper: https://doi.org/10.3847/1538-3881/ae03a4 (arXiv:2502.09790)
• License: CC BY 4.0, as the original.

Changes from the original

• The TFRecords were decoded and stored as Arrow/Parquet. Feature values are unchanged.
• Each TCE was joined with its catalog row (label, fold, paper_score).
• The data is split into labeled (57,162 TCEs) and unlabeled (147,567 TCEs).

Built with scripts/build_dataset.py from [TODO].

This is not an official NASA release and is not endorsed by NASA.

Columns

• uid, target_id: TCE and TIC identifiers.
• label: KP, CP, BD, EB, FP, NTP, NEB or NPC for labeled TCEs; UNK for unlabeled ones.
• fold: the paper's cross-validation fold 0-9; -1 for unlabeled TCEs.
• paper_score: the ExoMiner++ score from the original catalog.
• All other columns are the raw, unnormalized TFRecord features: scalars, 1-D views (31, 301 or 674 bins), the unfolded flux view (20 x 31) and the difference images (5 x 33 x 33).

Usage

import datasets
labeled = datasets.load_dataset("29thDay/exominer-plusplus", split="labeled")
labeled = labeled.with_format("numpy")
