SFT / LoRA fine‑tuning for scientific and engineering reasoning
Training "failure → re‑framing → hypothesis" behaviour rather than answer recall
Benchmarks and prompts exploring cross‑domain analogy generation
Research on synthetic reasoning data and self‑correction

Limitations

Fully synthetic, generated by Mistral‑Medium from expert‑system prompts. Historical narratives are plausible but not fact‑checked; treat context and failed_hypothesis as narrative scaffolding, not as a historical source.
novelty_score and implementation_feasibility are model self‑assessments on a narrow range, not calibrated measures.
Category labels are inconsistent (36 raw variants, including one‑off slash‑combined labels).
Duplicate themes exist across discovery_topic values; 4,434 unique topics over 5,001 records.
English only.

Provenance and repairs

Source: https://www.kaggle.com/datasets/dimsimd/kairos-thinking-5k, original file eureka_kairos_v1_5k.jsonl (31,039,929 bytes, 5,000 physical lines).

The upstream file contains two corrupt lines. Both were repaired without dropping any content, giving 5,001 valid records:

Line 4401 — duplicated object prefix: {"disc{"discovery_topic": "Biohybrid Robots", .... Removed the extra {"disc.
Line 5000 — two records concatenated, the second missing its opening {"discov: ...0.7}ery_topic": "Cold Storage via DNA Data Archiving", .... Split into two objects and restored the truncated key, yielding one extra valid record.

The untouched upstream file is kept at original/eureka_kairos_v1_5k.jsonl for verification. No other bytes were changed; field values, ordering and text are as published.
