Good morning!
Abstract: The advent of large language models (LLMs) has revolutionized natural language processing, enabling the generation of coherent and contextually relevant human-like text. As LLMs increasingly powerconversational agents used by the general public world-wide, the synthetic personality traits embedded in these models, by virtue of training on large amounts of human data, is becoming increasingly important. Since personality is a key factor determining the effectiveness of communication, we present a novel and comprehensive psychometrically valid and reliable methodology for administering and validating personality tests on widely-used LLMs, as well as for shaping personality in the generated text of such LLMs. Applying this method to 18 LLMs, we found: 1) personality measurements in the outputs of some LLMs under specific prompting configurations are reliable and valid; 2) evidence of reliability and validity of synthetic LLM personality is stronger for larger and instruction fine-tuned models; and 3) personality in LLM outputs can be shaped along desired dimensions to mimic specific human personality profiles. We discuss the application and ethical implications of the measurement and shaping method, in particular regarding responsible AI.
Presenter: Kim Zierahn
When: 27th of November at 10AM CET
Where: usual meeting link! :D
Looking forward to seeing you there :)
After a brief hiatus, we are back with the HCML reading group, with some small changes in the organization. Kim and Diego, two new PhD students at ELLIS Alicante, will take over from Piera and Gergely who recently defended their thesis! Additionally, we will run the reading group jointly with ELLIOT, a new Horizon Europe project.
The reading group will still be open to everyone, and you are always welcome to propose papers you would like to discuss :)
Here are the details of our upcoming session:
