Supporting many models simultaneously on a device is challenging due to the linearly increased co mputation\, energy\, and storage costs. An effective approach to address t he problem is multi-task learning (MTL) where a set of tasks are learned j ointly to allow some parameter sharing among tasks. MTL creates multi-task models based on common DNN architectures and has shown significantly redu ced inference costs and improved generalization performance in many machin e learning applications. In this talk\, we will introduce our recent effor ts on leveraging MTL to improve accuracy and efficiency for edge computing . The talk will introduce multi-task architecture design systems that can automatically identify resource-efficient multi-task models with low infer ence costs and high task accuracy.\n\nBiography\n\n\nHui Guan is an Assist ant Professor in the College of Information and Computer Sciences (CICS) a t the University of Massachusetts Amherst\, the flagship campus of the UMa ss system. She received her Ph.D. in Electrical Engineering from North Car olina State University in 2020. Her research lies in the intersection betw een machine learning and systems\, with an emphasis on improving the speed \, scalability\, and reliability of machine learning through innovations i n algorithms and programming systems. Her current research focuses on both algorithm and system optimizations of deep multi-task learning and graph machine learning.

\nNatural language provides an intuitive and powerful i nterface to access knowledge at scale. Modern language systems draw inform ation from two rich knowledge sources: (1) information stored in their par ameters during massive pretraining and (2) documents retrieved at inferenc e time. Yet\, we are far from building systems that can reliably provide i nformation from such knowledge sources. In this talk\, I will discuss path s for more robust systems. In the first part of the talk\, I will present a module for scaling retrieval-based knowledge augmentation. We learn a co mpressor that maps retrieved documents into textual summaries prior to in- context integration. This not only reduces the computational costs but als o filters irrelevant or incorrect information. In the second half of the t alk\, I will discuss the challenges of updating knowledge stored in model parameters and propose a method to prevent models from reciting outdated i nformation by identifying facts that are prone to rapid change. I will con clude my talk by proposing an interactive system that can elicit informati on from users when needed.
