Abstract:
The rapid advancement of AI has led to the emergence of massive, complex foundational models that require enormous computational resources, making efficient training and inference systems essential. Training these models involves distributing large-scale computations, optimizing resource usage through computation-communication overlap, employing advanced parallelization strategies, and ensuring fault tolerance at scale. Inference systems, on the other hand, must handle diverse workloads with varying SLAs, quickly adopt engineering optimizations, and balance trade-offs between throughput, latency, cost, and availability, particularly in distributed settings. In this talk, I will explore the key systems challenges in developing foundational models, including Qwen (large language models) and Wan (video generative models), and present our ongoing approaches to both training and inference at Alibaba. These designs significantly improve the efficiency of managing complex AI workloads in cloud environments.

Abstract:
Advances in AI are making it increasingly practical to extend traditional database management systems with the ability to query unstructured data, including images and videos, thus producing multimodal database management systems. In this talk, we will discuss some of the key components required for this integration, and will then focus specifically on video data management. A key challenge with video data management is the ability to cost-effectively
support complex queries in diverse applications and over video data from a variety of domains. We will present the VOCAL system and how it uses vision language models (VLMs) to achieve self-enhancing video data management, where the system extends its functionality to cost-effectively support compositional queries expressed in natural language in a variety of domains, increasing its capabilities with usage.
