Making large models and generative AI fast, reliable, and affordable at the edge
We build edge AI systems that coordinate heterogeneous edge devices with the cloud, so that LLMs, diffusion models, and other AI applications run efficiently under tight compute, memory, and bandwidth budgets. Our work spans LLM serving, efficient generative AI, and container scheduling and resource management, published at ICLR, ICML, ACM MM, IEEE TMC, IEEE TSC, and other venues.
Edge devices have limited compute, while cloud models are powerful but distant and costly. We study how to split requests, caches, and computation between cloud and edge to improve the latency, throughput, and quality of LLM services.
Real-world LLM applications are workflows of RAG, agents, and multiple models. We optimize entire workflows end to end on heterogeneous hardware.
Diffusion models for image and video generation run dozens of denoising steps. We exploit redundancy across steps with feature caching, feature forecasting, and multi-device collaboration to accelerate generation with little quality loss.
Edge clusters are resource-constrained and highly dynamic. We study layer-aware container scheduling, migration, and updates, cold-start optimization, and resource overbooking, using deep reinforcement learning and online algorithms.
Retrieval and question answering over images, text, audio, and video must be accurate, fast, and memory-efficient on edge devices.
Our long-standing work covers task offloading and scheduling, service placement, UAV and vehicular edge computing, crowdsourcing, and federated learning, as well as a survey of on-device AI models.
We are recruiting postdocs, PhD and master students, research assistants, and undergraduates.
