SoftQE: Learned Representations of Queries Expanded by LLMs

no code implementations20 Feb 2024 Varad Pimpalkhute, John Heyer, Xusen Yin, Sameer Gupta

We investigate the integration of Large Language Models (LLMs) into query encoders to improve dense retrieval without increasing latency and cost, by circumventing the dependency on LLMs at inference time.

Learning to Generalize for Sequential Decision Making

1 code implementation Findings of the Association for Computational Linguistics 2020 Xusen Yin, Ralph Weischedel, Jonathan May

However, the large amount of computation necessary to adequately train and explore the search space of sequential decision making, under a reinforcement learning paradigm, precludes the inclusion of large contextualized language models, which might otherwise enable the desired generalization ability.

Zero-Shot Learning of Text Adventure Games with Sentence-Level Semantics

no code implementations6 Apr 2020 Xusen Yin, Jonathan May

Reinforcement learning algorithms such as Q-learning have shown great promise in training models to learn the optimal action to take for a given system state; a goal in applications with an exploratory or adversarial nature such as task-oriented dialogues or games.

Learn How to Cook a New Recipe in a New House: Using Map Familiarization, Curriculum Learning, and Bandit Feedback to Learn Families of Text-Based Adventure Games

1 code implementation13 Aug 2019 Xusen Yin, Jonathan May

We consider the task of learning to play families of text-based computer adventure games, i. e., fully textual environments with a common theme (e. g. cooking) and goal (e. g. prepare a meal from a recipe) but with different specifics; new instances of such games are relatively straightforward for humans to master after a brief exposure to the genre but have been curiously difficult for computer agents to learn.
