Agentic-Ideation: Sample Efficient Agentic Trajectories Synthesis for Scientific Ideation Agents

2026-06-30 · Source: Artificial Intelligence · Field: Technology & Digital — Artificial Intelligence & Machine Learning, Robotics & Autonomous Systems · Depth: Expert, quick

Summary

The Agentic-Ideation framework addresses the high data synthesis cost in training agentic Large Language Models (LLMs) for scientific ideation. Existing LLM-based AI Scientist systems often rely on rigid, pre-defined workflows, limiting their flexibility in navigating complex scientific literature and research reasoning. Agentic-Ideation introduces an automated trajectory synthesis pipeline and a specialized agentic LLM. It defines a comprehensive tool space, including three external and three cognitive tools. A key component is the Oracle-Guided Data Synthesis strategy, which uses a reference idea as guidance to efficiently reconstruct logical reasoning and tool invocation paths, transforming trial-and-error into directed trajectory generation. The agent is then trained on these synthesized trajectories, utilizing a masking strategy on tool execution results to focus on decision-making logic. This method outperforms workflow-based baselines by 11.91% in overall quality and improves high-quality data synthesis sample efficiency by over 10x.

Key takeaway

For AI Scientists developing advanced ideation agents, Agentic-Ideation offers a path to overcome high data synthesis costs. You should consider implementing oracle-guided data synthesis to direct agent trajectory generation, significantly improving sample efficiency. This approach allows your models to focus on core decision-making logic by masking tool execution results, leading to an 11.91% quality improvement over workflow-based methods and over 10x better data synthesis efficiency.
