Researchers use RL to improve MLLM regression on imbalanced data

Researchers have developed a new framework to improve how multimodal large language models (MLLMs) handle numerical regression tasks, particularly those with imbalanced data distributions. Existing training methods often lead to poor performance on less frequent data points. The proposed solution uses a distribution-aware reinforcement learning approach with batch-level supervision to better align predicted and actual data distributions. Experiments demonstrated significant improvements over standard fine-tuning methods, especially in scenarios with limited training examples. AI
