YOU MAY ENJOY TO WATCH A TALK THAT ENTAILS THE DIGIDAN INSTALLATION:
I am working on the question of what digital replicas are and investigate their relation to their origins. Thereby I asked myself, how far can we get in developing language models like GPT-3 to let them represent the view of a philosopher?
WHAT is a GPT-3? A GPT-3 is a neural network trained to predict the next likely word in a sequence.
Technically, it is a 175 billion parameter language model that shows strong performances on many Natural Language Processing tasks. The abbreviation stands for Generative Pretrained Transformer!

This picture illustrates the project: On the left side, you see the complete work of a philosopher. In the middle, you see the GPT-3 we fine-tuned. On the right side, you see the not yet existing manual on how to operate this machine.
Experiment to evaluate the model in collaboration with Eric & David Schwitzgebel
We asked the real Dennett 10 philosophical questions and then posed the same questions to the language model, collecting four responses for each question without cherry-picking. Experts on Dennett's work succeeded at distinguishing the Dennett-generated and machine-generated answers above chance but substantially short of our expectations. Philosophy blog readers performed similarly to the experts, while ordinary research participants were near chance distinguishing GPT-3's responses from those of an “actual human philosopher”.
