Text Embedding Inversion Security for Multilingual Language Models

no code implementations22 Jan 2024 Yiyi Chen, Heather Lent, Johannes Bjerva

However, storing sensitive information as embeddings can be vulnerable to security breaches, as research shows that text can be reconstructed from embeddings, even without knowledge of the underlying model.

Patterns of Closeness and Abstractness in Colexifications: The Case of Indigenous Languages in the Americas

no code implementations18 Dec 2023 Yiyi Chen, Johannes Bjerva

Colexification refers to linguistic phenomena where multiple concepts (meanings) are expressed by the same lexical form, such as polysemy or homophony.

CreoleVal: Multilingual Multitask Benchmarks for Creoles

1 code implementation30 Oct 2023 Heather Lent, Kushal Tatariya, Raj Dabre, Yiyi Chen, Marcell Fekete, Esther Ploeger, Li Zhou, Ruth-Ann Armstrong, Abee Eijansantos, Catriona Malau, Hans Erik Heje, Ernests Lavrinovics, Diptesh Kanojia, Paul Belony, Marcel Bollmann, Loïc Grobol, Miryam de Lhoneux, Daniel Hershcovich, Michel DeGraff, Anders Søgaard, Johannes Bjerva

Creoles represent an under-explored and marginalized group of languages, with few available resources for NLP research. While the genealogical ties between Creoles and a number of highly-resourced languages imply a significant potential for transfer learning, this potential is hampered due to this lack of annotated data.

Colexifications for Bootstrapping Cross-lingual Datasets: The Case of Phonology, Concreteness, and Affectiveness

no code implementations5 Jun 2023 Yiyi Chen, Johannes Bjerva

Colexification refers to the linguistic phenomenon where a single lexical form is used to convey multiple meanings.

Efficient Residual Dense Block Search for Image Super-Resolution

3 code implementations25 Sep 2019 Dehua Song, Chang Xu, Xu Jia, Yiyi Chen, Chunjing Xu, Yunhe Wang

Focusing on this issue, we propose an efficient residual dense block search algorithm with multiple objectives to hunt for fast, lightweight and accurate networks for image super-resolution.
