Anderson Luis Bento Soares is a Master's student at the Institute of Computing, University of Campinas (Unicamp), affiliated with the Laboratório de Informática Visual (LIV). My research concerns fairness, ideological sycophancy, and the identification and mitigation of bias in large language models, with an emphasis on Brazilian educational and societal benchmarks.
About
Anderson Luis Bento Soares is a Master's student in Computer Science at the Institute of Computing, University of Campinas (Unicamp), and holds a Bachelor's degree in Computer Science from the Federal University of Ceará (UFC).
He conducts research at the Laboratório de Informática Visual (LIV) at Unicamp. His work focuses on identifying and mitigating biases in language models, particularly in scenarios involving political behavior, socioeconomic attribution, and stereotypes. He also works with knowledge graphs and retrieval-augmented generation as tools for grounding and evaluating model outputs.
