SpaceOmicsBench v3

A Multi-Omics AI Benchmark for Spaceflight Biomedical Data

SpaceOmicsBench v3 provides standardized ML and LLM evaluation infrastructure for spaceflight biomedical data from 4 human spaceflight missions (NASA Twins Study, Inspiration4, JAXA cfRNA, Axiom-2).

Dataset Structure

ML Track (Track A)

tasks/track_a/ — Task definitions (J1: phase classification, J2: clock acceleration)
tasks/track_c/ — Feature-level task definitions (C1: cfRNA DEG, C3: PPI benchmark)
data/tasks/ — Training data for J1 and J2 (n=20 samples)
data/axiom2_epigenetic/ — AX-2 epigenetic clock measurements (83 algorithms, 20 samples × 92 features)
data/external/string_ppi/ — STRING v12 PPI network topology features (17,995 genes × 4 features)
results/unified_baseline_results.json — Complete leaderboard (26 tasks, 16+ baseline methods)
results/track_a/ — Stage-level results (TabPFN, ESM2, GNN, fusion, feature selection)

LLM Track (Track B)

tasks/track_b/ — Question bank by category (12 categories, 270 questions)
evaluation/llm/question_bank_v3.json — Full 270Q bank with ground truth, difficulty, uncertainty flags
evaluation/llm/annotation_schema.json — Scoring rubric and 5-dimension framework

Key Statistics

26 ML tasks across 9 omics modalities (19 from v2 + 7 new)
270 LLM evaluation questions (12 categories, 4 difficulty levels)
4 spaceflight missions: NASA Twins (340d), Inspiration4 (3d), JAXA cfRNA, Axiom-2
Crew IDs: Anonymized (C001–C004 for I4, A001–A004 for AX-2)
