SocialCounterfactuals: Probing and Mitigating Intersectional Social Biases in Vision-Language Models with Counterfactual Examples

1 code implementation30 Nov 2023 Phillip Howard, Avinash Madasu, Tiep Le, Gustavo Lujan Moreno, Anahita Bhiwandiwalla, Vasudev Lal

Our approach utilizes Stable Diffusion with cross attention control to produce sets of counterfactual image-text pairs that are highly similar in their depiction of a subject (e. g., a given occupation) while differing only in their depiction of intersectional social attributes (e. g., race & gender).

Semi-Structured Chain-of-Thought: Integrating Multiple Sources of Knowledge for Improved Language Model Reasoning

no code implementations14 Nov 2023 Xin Su, Tiep Le, Steven Bethard, Phillip Howard

An important open question in the use of large language models for knowledge-intensive tasks is how to effectively integrate knowledge from three sources: the model's parametric memory, external structured knowledge, and external unstructured knowledge.

Probing Intersectional Biases in Vision-Language Models with Counterfactual Examples

no code implementations4 Oct 2023 Phillip Howard, Avinash Madasu, Tiep Le, Gustavo Lujan Moreno, Vasudev Lal

While vision-language models (VLMs) have achieved remarkable performance improvements recently, there is growing evidence that these models also posses harmful biases with respect to social attributes such as gender and race.

Logic and Constraint Logic Programming for Distributed Constraint Optimization

no code implementations7 May 2014 Tiep Le, Enrico Pontelli, Tran Cao Son, William Yeoh

The field of Distributed Constraint Optimization Problems (DCOPs) has gained momentum, thanks to its suitability in capturing complex problems (e. g., multi-agent coordination and resource allocation problems) that are naturally distributed and cannot be realistically addressed in a centralized manner.
