Dependability Evaluation of Stable Diffusion with Soft Errors on the Model Parameters

no code implementations30 Mar 2024 Zhen Gao, Lini Yuan, Pedro Reviriego, Shanshan Liu, Fabrizio Lombardi

In this paper, the dependability of Stable Diffusion is studied focusing on soft errors in the memory that stores the model parameters; specifically, errors are injected into some critical layers of the Transformer in different blocks of the image information creator, to evaluate their impact on model performance.

Concurrent Linguistic Error Detection (CLED) for Large Language Models

no code implementations25 Mar 2024 Jinhua Zhu, Javier Conde, Zhen Gao, Pedro Reviriego, Shanshan Liu, Fabrizio Lombardi

Since the proposed error detection mechanism only relies on the outputs of the model, then it can be used on LLMs in which there is no access to the internal nodes.

Open Source Conversational LLMs do not know most Spanish words

no code implementations21 Mar 2024 Javier Conde, Miguel González, Nina Melero, Raquel Ferrando, Gonzalo Martínez, Elena Merino-Gómez, José Alberto Hernández, Pedro Reviriego

The growing interest in Large Language Models (LLMs) and in particular in conversational models with which users can interact has led to the development of a large number of open-source chat LLMs.

Establishing Vocabulary Tests as a Benchmark for Evaluating Large Language Models

1 code implementation23 Oct 2023 Gonzalo Martínez, Javier Conde, Elena Merino-Gómez, Beatriz Bermúdez-Margaretto, José Alberto Hernández, Pedro Reviriego, Marc Brysbaert

Vocabulary tests, once a cornerstone of language modeling evaluation, have been largely overlooked in the current landscape of Large Language Models (LLMs) like Llama, Mistral, and GPT.

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.

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.

Concurrent Classifier Error Detection (CCED) in Large Scale Machine Learning Systems

no code implementations2 Jun 2023 Pedro Reviriego, Ziheng Wang, Alvaro Alonso, Zhen Gao, Farzad Niknia, Shanshan Liu, Fabrizio Lombardi

In this paper, we introduce Concurrent Classifier Error Detection (CCED), a scheme to implement CED in ML systems using a concurrent ML classifier to detect errors.

A brief introduction to satellite communications for Non-Terrestrial Networks (NTN)

no code implementations8 May 2023 Jose Alberto Hernandez, Pedro Reviriego

At present (year 2023), approximately 2, 500 satellites are currently orbiting the Earth.

Unfinished Architectures: A Perspective from Artificial Intelligence

no code implementations3 Mar 2023 Elena Merino-Gómez, Pedro Reviriego, Fernando Moral

Unfinished buildings are a constant throughout the history of architecture and have given rise to intense debates on the opportuneness of their completion, in addition to offering alibis for theorizing about the compositional possibilities in coherence with the finished parts.

Can Artificial Intelligence Reconstruct Ancient Mosaics?

no code implementations7 Oct 2022 Fernando Moral-Andrés, Elena Merino-Gómez, Pedro Reviriego, Fabrizio Lombardi

A large number of ancient mosaics have not reached us because they have been destroyed by erosion, earthquakes, looting or even used as materials in newer construction.

Text to Image Generation: Leaving no Language Behind

no code implementations19 Aug 2022 Pedro Reviriego, Elena Merino-Gómez

The results show that there is a significant performance degradation when using languages other than English, especially for languages that are not widely used.
