  Talk Title
  Beyond Scaling: Frontiers of Retrieval-Augmented Language Models

  Abstract
  Large Language Models (LMs) have demonstrated remarkable capabilities by scaling up training data and model sizes. However, they continue to face critical challenges, including hallucinations and outdated knowledge, which particularly limit their reliability in expert domains such as scientific research and software development. In this talk, I will urge the necessity of moving beyond the traditional scaling of monolithic LMs and advocate for Augmented LMs—a new AI paradigm that designs, trains, and deploys LMs alongside complementary modules to address these limitations. Focusing on my research on Retrieval-Augmented LMs, one of the most impactful and widely adopted forms of Augmented LMs today, I will begin by presenting our systematic analyses of current LM shortcomings and demonstrate how Retrieval-Augmented LMs offer a more effective and efficient path forward. I will then discuss my work to establish new foundations for further reliability and efficiency by designing and training new LMs and retrieval systems to dynamically adapt to diverse inputs. Finally, I will demonstrate the real-world impact of such Retrieval-Augmented LMs through OpenScholar, our fully open Retrieval-Augmented LM designed to assist scientists in synthesizing scientific literature, now used by more than 25,000 researchers and practitioners worldwide. I will conclude by outlining my vision for the future of Augmented LMs, emphasizing advancements in their abilities to handle heterogeneous and diverse modalities, more efficient and effective integration with diverse components, and advancing evaluations with interdisciplinary collaboration.

  Biography
  Akari Asai is a Ph.D. candidate in the Paul G. Allen School of Computer Science & Engineering at the University of Washington. Her research addresses the limitations of large language models (LMs) by developing advanced systems, such as Retrieval-Augmented LMs, and applying them to real-world challenges, including scientific research and underrepresented languages. Her contributions have received widespread recognition, including multiple paper awards at top NLP and ML conferences, the EECS Rising Stars 2022, and MIT Technology Review's Innovators Under 35 Japan. She has also been honored with the IBM Global Fellowship and several industry grants. Akari actively engages with the research community as a co-organizer of a tutorial and workshops, including the first tutorial on Retrieval-Augmented LMs at ACL 2023, as well as NAACL 2022 Workshop on Multilingual Information Access and NAACL 2025 Workshop on Knowledge-Augmented NLP.

  CS Seminar: Reusing Deep Learning Models: Challenges and Directions in Software Engineering: An Update (George K. Thiruvathukal)

  Department of Computer Science (CS)

  12:00 PM

  Speaker: George K. Thiruvathukal

  Talk Title: Reusing Deep Learning Models: Challenges and Directions in Software Engineering: An Update

  Abstract: Deep neural networks (DNNs) achieve state-of-the-art performance in many areas, including computer vision, system configuration, and question-answering. However, DNNs are expensive to develop, both in intellectual effort (e.g., devising new architectures) and computational costs (e.g., training). Re-using DNNs is a promising direction to amortize costs within a company and across the computing industry. As with any new technology, however, there are many challenges in re-using DNNs. These challenges include both missing technical capabilities and missing engineering practices. We discusschallenges in current approaches to DNN re-use. We summarize studies of re-use failures across the spectrum of re-use techniques, including conceptual (e.g., re-using based on a research paper), adaptation (e.g., re-using by building on an existing implementation), and deployment (e.g., direct re-use on a new device). We outline possible advances that would improve each kind of re-use.

  In this update of my invited presentation at IEEE Services 2023 at the John Vincent Atanasoff Sypmposium on Modern Computing, I will include information about our work in progress on the use of Deep Learning and Pre-Trained Models (PTMs) in science and engineering applications and our efforts to conduct automated longitudinal analysis of same.
