Adverse weather amplifies social media activity

no code implementations16 Feb 2023 Kelton Minor, Esteban Moro, Nick Obradovich

Weather that is adverse on both the temperature and precipitation dimensions produces markedly larger increases in social media activity.

Evidence of behavior consistent with self-interest and altruism in an artificially intelligent agent

no code implementations5 Jan 2023 Tim Johnson, Nick Obradovich

The agent's altruistic behaviors, moreover, vary by recipient: the AI agent shared substantially less of the endowment with the human experimenter or an anonymous charity than with other AI agents.

Measuring an artificial intelligence agent's trust in humans using machine incentives

no code implementations27 Dec 2022 Tim Johnson, Nick Obradovich

Furthermore, to address the possibility that the AI agent's trust decisions reflect a preference for uncertainty, the experiments include two conditions that present the AI agent with a non-social decision task that provides the opportunity to choose a certain or uncertain option; in those conditions, the AI agent consistently chooses the certain option.

Algorithmic Discrimination: Formulation and Exploration in Deep Learning-based Face Biometrics

1 code implementation4 Dec 2019 Ignacio Serna, Aythami Morales, Julian Fierrez, Manuel Cebrian, Nick Obradovich, Iyad Rahwan

We experimentally show that demographic groups highly represented in popular face databases have led to popular pre-trained deep face models presenting strong algorithmic discrimination.

Face Recognition

Human detection of machine manipulated media

no code implementations6 Jul 2019 Matthew Groh, Ziv Epstein, Nick Obradovich, Manuel Cebrian, Iyad Rahwan

Here we report on a randomized experiment designed to study the effect of exposure to media manipulations on over 15, 000 individuals' ability to discern machine-manipulated media.

1 code implementation NAACL 2019 Remi Mir, Bjarke Felbo, Nick Obradovich, Iyad Rahwan

Research in the area of style transfer for text is currently bottlenecked by a lack of standard evaluation practices.
