Improve LLM idea generation with set-level reinforcement learning
Train models to score idea sets jointly, weighting new ideas by their distance from previous ones.
Train models using a set-level reinforcement learning objective where the model generates K structured idea cards grounded in source papers. The set is scored jointly, with each idea's quality weighted by its distance from preceding ideas.
This approach teaches the model to generate ideas that are not only high-quality but also distinct from one another, directly addressing the oversight of diversity in most LLM ideation work.
A model trained this way might propose a set of scientific hypotheses for a given research paper, ensuring each hypothesis is novel and not just a minor variation of another in the set.
This heuristic describes a method to enhance LLM-generated scientific ideas by focusing on diversity. It involves training models with a set-level reinforcement learning objective that scores idea sets jointly, penalizing ideas too similar to previous ones.
By explicitly weighting new ideas based on their distance from prior ones within a single generation, the model learns to actively steer away from redundancy, thereby increasing the diversity of its output.
