LLM-based clustering generates hard negatives for real-time retrieval model training

By PulseAugur Editorial · [1 sources] ·

A new research paper introduces a self-supervised method for generating "hard negatives" in real-time during the training of large-scale two-tower retrieval models. This technique utilizes a large language model (LLM) to cluster media representations, ensuring that the generated negatives are more challenging and informative than traditional in-batch or out-of-batch methods. The proposed framework is designed for seamless integration into production systems, capable of handling billions of data points with minimal computational overhead. Experiments and deployment in a large-scale online system demonstrate its superiority over existing industry methods, showing it can break feedback loops and reduce popularity bias in recommendations. AI

IMPACT This method could improve the effectiveness of recommendation systems by generating more informative training data, potentially reducing bias and improving user experience.

    Real-Time Hard Negative Sampling via LLM-based Clustering for Large-Scale Two-Tower Retrieval

    The two-tower model has been widely used for large-scale recommendation systems, particularly in the retrieval stage. Industry standards for training two-tower models typically involve in-batch and/or out-of-batch negative sampling. However, these methods often produce easy negat…
