LgTS: Dynamic Task Sampling using LLM-generated sub-goals for Reinforcement Learning Agents

no code implementations14 Oct 2023 Yash Shukla, Wenchang Gao, Vasanth Sarathy, Alvaro Velasquez, Robert Wright, Jivko Sinapov

In this work, we propose LgTS (LLM-guided Teacher-Student learning), a novel approach that explores the planning abilities of LLMs to provide a graphical representation of the sub-goals to a reinforcement learning (RL) agent that does not have access to the transition dynamics of the environment.

RAPid-Learn: A Framework for Learning to Recover for Handling Novelties in Open-World Environments

1 code implementation24 Jun 2022 Shivam Goel, Yash Shukla, Vasanth Sarathy, Matthias Scheutz, Jivko Sinapov

We propose RAPid-Learn: Learning to Recover and Plan Again, a hybrid planning and learning method, to tackle the problem of adapting to sudden and unexpected changes in an agent's environment (i. e., novelties).

From Unstructured Text to Causal Knowledge Graphs: A Transformer-Based Approach

no code implementations23 Feb 2022 Scott Friedman, Ian Magnusson, Vasanth Sarathy, Sonja Schmer-Galunder

Qualitative causal relationships compactly express the direction, dependency, temporal constraints, and monotonicity constraints of discrete or continuous interactions in the world.

SPOTTER: Extending Symbolic Planning Operators through Targeted Reinforcement Learning

no code implementations24 Dec 2020 Vasanth Sarathy, Daniel Kasenberg, Shivam Goel, Jivko Sinapov, Matthias Scheutz

Symbolic planning models allow decision-making agents to sequence actions in arbitrary ways to achieve a variety of goals in dynamic domains.

Reasoning Requirements for Indirect Speech Act Interpretation

no code implementations COLING 2020 Vasanth Sarathy, Alexander Tsuetaki, Antonio Roque, Matthias Scheutz

We perform a corpus analysis to develop a representation of the knowledge and reasoning used to interpret indirect speech acts.

Developing a Corpus of Indirect Speech Act Schemas

no code implementations LREC 2020 Antonio Roque, Alex Tsuetaki, er, Vasanth Sarathy, Matthias Scheutz

Resolving Indirect Speech Acts (ISAs), in which the intended meaning of an utterance is not identical to its literal meaning, is essential to enabling the participation of intelligent systems in peoples{'} everyday lives.

Quasi-Dilemmas for Artificial Moral Agents

no code implementations6 Jul 2018 Daniel Kasenberg, Vasanth Sarathy, Thomas Arnold, Matthias Scheutz, Tom Williams

In this paper we describe moral quasi-dilemmas (MQDs): situations similar to moral dilemmas, but in which an agent is unsure whether exploring the plan space or the world may reveal a course of action that satisfies all moral requirements.

The MacGyver Test - A Framework for Evaluating Machine Resourcefulness and Creative Problem Solving

no code implementations26 Apr 2017 Vasanth Sarathy, Matthias Scheutz

Current measures of machine intelligence are either difficult to evaluate or lack the ability to test a robot's problem-solving capacity in open worlds.

Enabling Basic Normative HRI in a Cognitive Robotic Architecture

no code implementations11 Feb 2016 Vasanth Sarathy, Jason R. Wilson, Thomas Arnold, Matthias Scheutz

Collaborative human activities are grounded in social and moral norms, which humans consciously and subconsciously use to guide and constrain their decision-making and behavior, thereby strengthening their interactions and preventing emotional and physical harm.
