This collaboration exemplifies our commitment to advancing AI and machine learning technologies through partnerships with leading research institutions.

[15/10/2024] $\bullet$ Two research papers from our team have been accepted for presentation at the 26th International Conference on High Performance Computing and Communications (HPCC2024). The accepted papers are titled “Incremental Label Distribution Learning With Scalable Graph Convolutional Networks” and “ESARM: 3D Emotional Speech-To-Animation via Reward Model From Automatically-Ranked Demonstrations.” HPCC2024 is a leading forum for advances in high-performance computing and communications technology. Sponsored by IEEE, the conference brings together experts from academia, industry, and government to address challenges and present innovations in theoretical foundations, systems, infrastructure, tools, and applications. This year’s event continues the conference’s tradition of showcasing cutting-edge research and defining future directions in the rapidly evolving field of high-performance computing. Our team’s participation underscores our commitment to pushing the boundaries of this critical technology.

[20/09/2024] $\bullet$ We are thrilled to announce that our paper, “IDEAW: Robust Neural Audio Watermarking with Invertible Dual-Embedding,” has been officially accepted for presentation at the prestigious EMNLP 2024 main conference! IDEAW represents a significant advancement in neural audio watermarking, and we are excited to share our findings with the NLP community at this premier event.

[16/07/2024] $\bullet$ Today announced the acceptance of its groundbreaking research paper, “Beyond Aggregation: Efficient Federated Model Consolidation with Heterogeneity-Adaptive Weights Diffusion,” at the prestigious Conference on Information and Knowledge Management (CIKM) 2024. This innovative work addresses the critical challenge of communication costs in Federated Learning (FL), a privacy-preserving approach to training machine learning models across decentralized devices. The team pioneers the use of diffusion models, renowned for their success in AI-generated content, to revolutionize how model weights are consolidated on the server-side of FL systems. Our FedDiff method not only significantly reduces communication overhead but also demonstrates remarkable convergence speed, accuracy, and robustness against noise. This research has the potential to unlock broader real-world applications of Federated Learning in fields like healthcare, finance, and IoT. CIKM is an international forum for presenting and discussing cutting-edge research in information and knowledge management. Acceptance at CIKM underscores the significance and quality of this research contribution.

[16/05/2024] $\bullet$ It feels amazing to receive an acceptance notification from a top-tier conference on a weekday afternoon! The latest research paper “Superfiltering: Weak-to-Strong Data Filtering for Fast Instruction-Tuning,” a collaboration between Ping An Technology’s Dr. Jianzong Wang’s team and Professor Tianyi Zhou’s team from the University of Maryland, has been accepted as a long paper at ACL 2024 CCF Class A paper, with an acceptance rate of less than 20%. This represents a significant breakthrough in the field of instruction-tuning for large models. For the first time, we have revealed the consistency in instruction difficulty perception across models of different scales and achieved over a 20-fold speed improvement in the large model training process through our superfiltering method. This achievement opens up new avenues for data filtering technology. We welcome citations from our peers! Research Highlights: 1. Weak-to-Strong Data Consistency: We discovered that both small and large language models exhibit a high degree of consistency in perceiving and evaluating the difficulty of instruction-tuning data. This finding is crucial for optimizing data filtering processes. 2. Efficient Superfiltering Strategy: We proposed the first superfiltering method that uses small models (e.g., GPT-2) to select data, significantly accelerating the fine-tuning process of large language models. 3. Effectiveness of Selected Training Data: Superfiltering is highly precise in allocating high-quality and information-rich data. Models trained with only 5% of the filtered data performed similarly to or even better than models trained with the entire dataset in multiple benchmark tests. The complete research results and code are publicly available on GitHub: https://github.com/tianyi-lab/Superfiltering. This is our second paper at a top NLP conference. Our team’s collaboration with the University of Maryland has already resulted in a paper published at NAACL, addressing the innovative problem of how to automatically identify high-quality instruction data from datasets during large model training.
