AI "News" Content Farms Are Easy to Make and Hard to Detect: A Case Study in Italian

no code implementations17 Jun 2024 Giovanni Puccetti, Anna Rogers, Chiara Alzetta, Felice Dell'Orletta, Andrea Esuli

Large Language Models (LLMs) are increasingly used as "content farm" models (CFMs), to generate synthetic text that could pass for real news articles.

The Invalsi Benchmarks: measuring Linguistic and Mathematical understanding of Large Language Models in Italian

no code implementations27 Mar 2024 Giovanni Puccetti, Maria Cassese, Andrea Esuli

For both Invalsi MATE and Invalsi ITA we compare LLMs with the average performance of Italian students to show that Llama 3. 1 is the only one to outperform them on Invalsi MATE while most models do so on Invalsi ITA, we then show that Olimpiadi MATE is more challenging than Invalsi MATE and the highest accuracy, achieved by Llama 3. 1 405b instruct is 45%.

Outliers Dimensions that Disrupt Transformers Are Driven by Frequency

1 code implementation23 May 2022 Giovanni Puccetti, Anna Rogers, Aleksandr Drozd, Felice Dell'Orletta

While Transformer-based language models are generally very robust to pruning, there is the recently discovered outlier phenomenon: disabling only 48 out of 110M parameters in BERT-base drops its performance by nearly 30% on MNLI.
