Counterfactual Token Generation in Large Language Models

1 code implementation25 Sep 2024 Ivi Chatzi, Nina Corvelo Benz, Eleni Straitouri, Stratis Tsirtsis, Manuel Gomez-Rodriguez

Our model allows any large language model to perform counterfactual token generation at almost no cost in comparison with vanilla token generation, it is embarrassingly simple to implement, and it does not require any fine-tuning nor prompt engineering.

Controlling Counterfactual Harm in Decision Support Systems Based on Prediction Sets

1 code implementation10 Jun 2024 Eleni Straitouri, Suhas Thejaswi, Manuel Gomez Rodriguez

In this paper, our goal is to control how frequently a decision support system based on prediction sets may cause harm, by design.

Towards Human-AI Complementarity with Predictions Sets

1 code implementation27 May 2024 Giovanni De Toni, Nastaran Okati, Suhas Thejaswi, Eleni Straitouri, Manuel Gomez-Rodriguez

Then, we show that the problem of finding the optimal prediction sets under which the human experts achieve the highest average accuracy is NP-hard.

Prediction-Powered Ranking of Large Language Models

1 code implementation27 Feb 2024 Ivi Chatzi, Eleni Straitouri, Suhas Thejaswi, Manuel Gomez Rodriguez

Using pairwise comparisons made by humans in the LMSYS Chatbot Arena platform and pairwise comparisons made by three strong large language models, we empirically demonstrate the effectivity of our framework and show that the rank-sets constructed using only pairwise comparisons by the strong large language models are often inconsistent with (the distribution of) human pairwise preferences.

Designing Decision Support Systems Using Counterfactual Prediction Sets

1 code implementation6 Jun 2023 Eleni Straitouri, Manuel Gomez Rodriguez

In this context, it has been recently argued that an alternative type of decision support systems may circumvent this challenge.

Improving Expert Predictions with Conformal Prediction

1 code implementation28 Jan 2022 Eleni Straitouri, Lequn Wang, Nastaran Okati, Manuel Gomez Rodriguez

In this work, we develop an automated decision support system that, by design, does not require experts to understand when to trust the system to improve performance.

Reinforcement Learning Under Algorithmic Triage

no code implementations23 Sep 2021 Eleni Straitouri, Adish Singla, Vahid Balazadeh Meresht, Manuel Gomez-Rodriguez

Methods to learn under algorithmic triage have predominantly focused on supervised learning settings where each decision, or prediction, is independent of each other.
