My research interests center on the intersection of natural language processing, machine learning, and multi-agent systems. Specifically, I am interested in exploring how large language models (LLMs) can communicate and collaborate to solve complex tasks together, and how they can be trained to specialize in different domains for a division of labor. My key focus areas include:
- Inducing Latent Language for Inter-LLM Communication: Developing methods to induce a specialized language for LLM communication, thereby enabling LLMs to leverage each other’ s expertise.
- Communication for Models Across Modalities: Extending Inter-LLM communication methods to enable collaboration among models that specialize in different modalities, such as language, image, and sensory data.
- Collaborative Training for Division of Labor among Models: Exploring ways to foster a division of labor among models, using communication as a tool to distribute knowledge among them during the training process.
I also work on open-source projects such as OpenNMT, Im2LaTeX, LaTeX2Im, and Steganography to make my research efforts more readily available for developers and researchers.
