137 - Nearest Neighbor Language Modeling and Machine Translation, with Urvashi Khandelwal

Author: Allen Institute for Artificial Intelligence January 14, 2023 Duration: 35:56
We invited Urvashi Khandelwal, a research scientist at Google Brain to talk about nearest neighbor language and machine translation models. These models interpolate parametric (conditional) language models with non-parametric distributions over the closest values in some data stores built from relevant data. Not only are these models shown to outperform the usual parametric language models, they also have important implications on memorization and generalization in language models. Urvashi's webpage: https://urvashik.github.io Papers discussed: 1) Generalization through memorization: Nearest Neighbor Language Models (https://www.semanticscholar.org/paper/7be8c119dbe065c52125ee7716601751f3116844) 2)Nearest Neighbor Machine Translation (https://www.semanticscholar.org/paper/20d51f8e449b59c7e140f7a7eec9ab4d4d6f80ea)

While NLP Highlights is currently on hiatus, its archive remains a compelling snapshot of conversations from the front lines of computational linguistics. Produced by the Allen Institute for Artificial Intelligence, this science podcast carved out a space for deep, researcher-led discussions about natural language processing. Each episode functions as an informal seminar, where the people actively designing algorithms and pushing the field forward explain their work in their own words. You'll hear about the nuanced challenges behind making machines understand, generate, and reason with human language, from foundational theories to unexpected applications. The dialogue in this podcast often delves into the "why" behind the research, not just the results, offering clarity on complex topics like machine translation, sentiment analysis, or large language models. It’s a chance to listen as experts articulate their thought processes, debates, and moments of insight, with all the candidness that comes from a conversation between peers. The views shared are personal perspectives from the hosts and their guests, independent of their affiliated institutions. For anyone curious about how machines learn to parse meaning, the archived episodes of NLP Highlights provide a thoughtful and accessible entry point.
