Understanding the Impact of Artificial Intelligence in Academic Writing: Metadata to the Rescue

no code implementations23 Feb 2025 Javier Conde, Pedro Reviriego, Joaquín Salvachúa, Gonzalo Martínez, José Alberto Hernández, Fabrizio Lombardi

This column advocates for including artificial intelligence (AI)-specific metadata on those academic papers that are written with the help of AI in an attempt to analyze the use of such tools for disseminating research.

Designing Reliable Experiments with Generative Agent-Based Modeling: A Comprehensive Guide Using Concordia by Google DeepMind

no code implementations11 Nov 2024 Alejandro Leonardo García Navarro, Nataliia Koneva, Alfonso Sánchez-Macián, José Alberto Hernández, Manuel Goyanes

In social sciences, researchers often face challenges when conducting large-scale experiments, particularly due to the simulations' complexity and the lack of technical expertise required to develop such frameworks.

How many words does ChatGPT know? The answer is ChatWords

1 code implementation28 Sep 2023 Gonzalo Martínez, Javier Conde, Pedro Reviriego, Elena Merino-Gómez, José Alberto Hernández, Fabrizio Lombardi

The benefits of ChatWords are illustrated with two case studies: evaluating the knowledge that ChatGPT has of the Spanish lexicon (taken from the official dictionary of the "Real Academia Espa\~nola") and of the words that appear in the Quixote, the well-known novel written by Miguel de Cervantes.

Launch Power Optimization for Dynamic Elastic Optical Networks over C+L Bands

no code implementations25 Aug 2023 Farhad Arpanaei, Mahdi Ranjbar Zefreh, José Alberto Hernández, Behnam Shariati, Johannes Fischer, José Manuel Rivas-Moscoso, Filipe Jiménez, Juan Pedro Fernández-Palacios, David Larrabeiti

We propose an algorithm for calculating the optimum launch power over the entire C+L bands by maximizing the cumulative link GSNR of a channel plan built upon multiple modulation formats, with application to dynamic EONs.

Playing with Words: Comparing the Vocabulary and Lexical Richness of ChatGPT and Humans

no code implementations14 Aug 2023 Pedro Reviriego, Javier Conde, Elena Merino-Gómez, Gonzalo Martínez, José Alberto Hernández

Therefore, further research is needed to understand how the use of ChatGPT and more broadly generative AI tools will affect the vocabulary and lexical richness in different types of text and languages.

Towards Understanding the Interplay of Generative Artificial Intelligence and the Internet

1 code implementation8 Jun 2023 Gonzalo Martínez, Lauren Watson, Pedro Reviriego, José Alberto Hernández, Marc Juarez, Rik Sarkar

Our results show that the quality and diversity of the generated images can degrade over time suggesting that incorporating AI-created data can have undesired effects on future versions of generative models.
