Ideation Arena: Evaluating LLM Generated Research Ideas with Battle-style Human Expert Assessment

Ideation Arena is a battle-style platform that evaluates research ideas generated by large language models (LLMs) and research agents through pairwise human assessment. The system builds shared literature contexts, collects over 6,000 double-blind comparisons from 105 computer science researchers, and constructs an Elo rating leaderboard to rank proposal-stage expert preferences. It also introduces Ideation Arena Eval, a benchmark to test whether automated evaluators align with human preferences, finding that current LLM judges achieve at best 72.56% Soft Accuracy on overall quality.

Do AI Scientists Know What's New?

The paper introduces ClaimNov, a claim‑level novelty detection module designed to improve AI scientific discovery pipelines. By evaluating novelty at the proposal and claim levels using four datasets of 1,060 proposals, the authors show that existing checks either reject too many novel ideas or fail to isolate non‑novel parts of a proposal. ClaimNov achieves a 97% detection rate of disguised papers with only a 1.5% false‑alarm rate, significantly reducing false positives compared to prior methods and preserving proposals that build on established work.

Sci$\Pi$vot: Benchmarking Principal-Investigator Judgment at Pivotal Moments of Scientific AutoResearch Agents

Sciπvot is a 248‑case benchmark that evaluates how well large language model (LLM) agents perform scientific judgment during autonomous research. The benchmark is built from six months of real‑world experiments where senior researchers ran LLM agents on 26 projects across six scientific fields and repeatedly corrected the agents’ decisions. In each case, the agent must choose between its original plan and a human‑corrected alternative using only the project record available before the correction, allowing a direct comparison of LLM and human performance under varying reasoning effort and record access.
