Beijing, China – April 1, 2024 – In a significant achievement for Chinese AI research, a joint team from the Institute for Digital Economy and Artificial Intelligence (IDEA), Tsinghua University, Peking University, and the Hong Kong University of Science and Technology (Guangzhou) has secured an Oral presentation at the prestigious International Conference on Learning Representations (ICLR) 2025 for their groundbreaking work, ChartMoE. Their paper, titled ChartMoE: Exploring Representations and Knowledge in Diversely Aligned Mixture-of-Experts for Downstream Tasks, introduces a novel approach to enhancing machine understanding of charts using a Mixture-of-Experts (MoE) architecture.
ICLR, a leading global conference in AI and machine learning, is highly competitive. This year’s conference received a staggering 11,672 submissions, with only approximately 1.8% selected for Oral presentation, highlighting the significance of the ChartMoE’s acceptance.
The research addresses a critical need in the field of AI: enabling machines to effectively interpret and utilize information presented in visual formats like charts and graphs. While large language models (LLMs) have demonstrated impressive capabilities in natural language processing, their ability to reason about and extract insights from visual data remains a challenge.
The ChartMoE model, detailed in the paper available on arXiv (https://arxiv.org/abs/2409.03277), offers a unique solution. Unlike conventional applications of MoE architectures that primarily focus on scaling model capacity, the ChartMoE project leverages the sparse structure of MoEs to improve performance on downstream tasks related to chart understanding. The core innovation lies in aligning the MoE architecture with specific tasks, thereby enhancing the model’s ability to comprehend and reason about graphical data.
Our goal wasn’t simply to build a larger model, explains [Spokesperson from the research team – Note: No specific name provided in source material, so this is a placeholder]. We wanted to explore how the MoE architecture could be strategically utilized to improve the understanding of charts and graphs, while maintaining strong performance on other general tasks.
The team’s approach distinguishes itself from previous methods that rely on random or co-upcycle initialization. ChartMoE leverages a multi-faceted alignment strategy to guide the learning process, resulting in a more robust and interpretable model.
The research team has made their code, model, and data publicly available, fostering collaboration and further advancements in the field:

The acceptance of ChartMoE at ICLR 2025 underscores the growing strength of Chinese research in AI and its commitment to pushing the boundaries of machine learning. The model’s innovative approach to chart understanding holds significant potential for applications across various industries, including finance, healthcare, and data analytics, where the ability to extract meaningful insights from visual data is crucial. The research team’s open-source approach will undoubtedly accelerate further progress in this important area.
Conclusion:
The ChartMoE model represents a significant step forward in enabling machines to understand and reason about visual data. By strategically leveraging the Mixture-of-Experts architecture and focusing on task-specific alignment, the research team has developed a novel approach that holds promise for improving performance on downstream tasks related to chart understanding. The open-source release of the code, model, and data will facilitate further research and development in this important area, paving the way for more intelligent and insightful AI systems. Future research could explore the application of ChartMoE to other visual data formats and investigate methods for further improving the model’s interpretability and robustness.
