Towards the design of user-centric strategy recommendation systems for collaborative Human-AI tasks

no code implementations17 Jan 2023 Lakshita Dodeja, Pradyumna Tambwekar, Erin Hedlund-Botti, Matthew Gombolay

While these strategy recommendation schemes have been explored independently in prior work, our study is novel in that we employ all of them simultaneously and in the context of strategy recommendations, to provide us an in-depth overview of the perception of different strategy recommendation systems.

Towards Reconciling Usability and Usefulness of Explainable AI Methodologies

no code implementations13 Jan 2023 Pradyumna Tambwekar, Matthew Gombolay

Our findings highlight internal consistency issues wherein participants perceived language explanations to be significantly more usable, however participants were better able to objectively understand the decision making process of the car through a decision tree explanation.

FedPC: Federated Learning for Language Generation with Personal and Context Preference Embeddings

no code implementations7 Oct 2022 Andrew Silva, Pradyumna Tambwekar, Matthew Gombolay

Federated learning is a training paradigm that learns from multiple distributed users without aggregating data on a centralized server.

A Computational Interface to Translate Strategic Intent from Unstructured Language in a Low-Data Setting

1 code implementation17 Aug 2022 Pradyumna Tambwekar, Lakshita Dodeja, Nathan Vaska, Wei Xu, Matthew Gombolay

Leveraging a game environment, we collect a dataset of over 1000 examples, mapping language strategies to the corresponding goals and constraints, and show that our model, trained on this dataset, significantly outperforms human interpreters in inferring strategic intent (i. e., goals and constraints) from language (p < 0. 05).

Towards a Comprehensive Understanding and Accurate Evaluation of Societal Biases in Pre-Trained Transformers

no code implementations NAACL 2021 Andrew Silva, Pradyumna Tambwekar, Matthew Gombolay

The ease of access to pre-trained transformers has enabled developers to leverage large-scale language models to build exciting applications for their users.

Natural Language Specification of Reinforcement Learning Policies through Differentiable Decision Trees

1 code implementation18 Jan 2021 Pradyumna Tambwekar, Andrew Silva, Nakul Gopalan, Matthew Gombolay

Human-AI policy specification is a novel procedure we define in which humans can collaboratively warm-start a robot's reinforcement learning policy.

Automated Rationale Generation: A Technique for Explainable AI and its Effects on Human Perceptions

no code implementations11 Jan 2019 Upol Ehsan, Pradyumna Tambwekar, Larry Chan, Brent Harrison, Mark Riedl

The second study further explores user preferences between the generated rationales with regard to confidence in the autonomous agent, communicating failure and unexpected behavior.

Controllable Neural Story Plot Generation via Reward Shaping

1 code implementation27 Sep 2018 Pradyumna Tambwekar, Murtaza Dhuliawala, Lara J. Martin, Animesh Mehta, Brent Harrison, Mark O. Riedl

Language-modeling--based approaches to story plot generation attempt to construct a plot by sampling from a language model (LM) to predict the next character, word, or sentence to add to the story.
