Abstract
\nLarge Language Models (LLM s) have demonstrated remarkable capabilities across various domains. Howev er\, it is still very challenging to build highly-reliable applications wi th LLMs that support specialized use cases. LLMs trained on web data often excel at capturing general language patterns\, but they could struggle to support specialized domains and personalized user needs. Moreover\, LLMs can produce errors that are deceptively plausible\, making them potentiall y dangerous for high-trust scenarios. In this talk\, I will discuss some o f our recent efforts in addressing these challenges with data-efficient tu ning methods and a novel factuality evaluation framework. Specifically\, m y talk will focus on building multilingual applications\, one crucial use case often characterized by limited tuning and evaluation data.
\nBio
Xinyi(Cindy) Wang is a research scientist at Go ogle DeepMind working on Large Language Models(LLM) and its application to generative question-answering. She has worked on multilingual instruction -tuning for Gemini and multilingual generative models used in Google searc h. Before Google DeepMind\, Cindy Wang obtained her PhD degree in Language Technologies at Carnegie Mellon University. During her PhD\, she mainly w orked on developing data-efficient natural language processing~(NLP) syste ms. She has made several contributions in data selection\, data representa tion\, and model adaptation for multilingual NLP.

\nNatural language provides an intuitive and powerful interface to access knowledge at scale. Modern l anguage systems draw information from two rich knowledge sources: (1) info rmation stored in their parameters during massive pretraining and (2) docu ments retrieved at inference time. Yet\, we are far from building systems that can reliably provide information from such knowledge sources. In this talk\, I will discuss paths 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 compressor that maps retrieved documents into tex tual summaries prior to in-context integration. This not only reduces the computational costs but also filters irrelevant or incorrect information. In the second half of the talk\, I will discuss the challenges of updating knowledge stored in model parameters and propose a method to prevent mode ls from reciting outdated information by identifying facts that are prone to rapid change. I will conclude my talk by proposing an interactive syste m that can elicit information from users when needed.
