A Mixture-of-Experts Approach to Few-Shot Task Transfer in Open-Ended Text Worlds

Christopher Z. Cui, Xiangyu Peng, Mark O. Riedl

Open-ended worlds are those in which there are no pre-specified goals or environmental reward signal. As a consequence, an agent must know how to perform a multitude of tasks. Howe…

Thespian: Multi-Character Text Role-Playing Game Agents

Christopher Cui, Xiangyu Peng, Mark Riedl

Text-adventure games and text role-playing games are grand challenges for reinforcement learning game playing agents. Text role-playing games are open-ended environments where an a…

Ambient Adventures: Teaching ChatGPT on Developing Complex Stories

Zexin Chen, Eric Zhou, Kenneth Eaton +2

Imaginative play is an area of creativity that could allow robots to engage with the world around them in a much more personified way. Imaginary play can be seen as taking real obj…

Neuro-Symbolic World Models for Adapting to Open World Novelty

Jonathan Balloch, Zhiyu Lin, Robert Wright +5

Open-world novelty--a sudden change in the mechanics or properties of an environment--is a common occurrence in the real world. Novelty adaptation is an agent's ability to improve…

Model ensemble instead of prompt fusion: a sample-specific knowledge transfer method for few-shot prompt tuning

Xiangyu Peng, Chen Xing, Prafulla Kumar Choubey +2

Prompt tuning approaches, which learn task-specific soft prompts for a downstream task conditioning on frozen pre-trained models, have attracted growing interest due to its paramet…

Detecting and Adapting to Novelty in Games

Xiangyu Peng, Jonathan C. Balloch, Mark O. Riedl

Open-world novelty occurs when the rules of an environment can change abruptly, such as when a game player encounters "house rules". To address open-world novelty, game playing age…

Reducing Non-Normative Text Generation from Language Models

Xiangyu Peng, Siyan Li, Spencer Frazier +1

Large-scale, transformer-based language models such as GPT-2 are pretrained on diverse corpora scraped from the internet. Consequently, they are prone to generating non-normative t…
