The 30-second scan

Ask a strong AI to invent a research idea and it will hand you something reasonable.

  1. For each paper, the framework reverse-engineers a small set of closely related prior works that likely inspired its core idea.
  2. LLMs are prompted to generate a new idea from the set of paper titles and summaries.
  3. The authors introduce a two-axis research-taste taxonomy that profiles each idea by its opportunity pattern and research paradigm.
