17. Commentary on article on coding hate speech offers nuanced look at limits of AI systemsЧт, 08 мая[-/+]

Категория^(?)

Large language models (LLMs) are artificial intelligence (AI) systems that can understand and generate human language by analyzing and processing large amounts of text. In a new essay, a Carnegie Mellon University researcher critiques an article on LLMs and provides a nuanced look at the models' limits for analyzing sensitive discourse, such as hate speech. The commentary is published in the Journal of Multicultural Discourses.

18. New study explores role of generative AI in using copyrighted materialЧт, 08 мая[-/+]

Категория^(?)

Generative artificial intelligence (AI) facilitates the compilation of huge volumes of data, which often include copyrighted materials. While debates about the legality of the process abound, in a recent report issued by the US Copyright Office, researchers examine to what degree allowing or restricting this practice serves the economic objectives of copyright. In short, does AI shift the balance between incentives and access, and what policies could recalibrate that balance?
