Today in 1943, Warren S. McCulloch and Walter Pitts published “A logical calculus of the ideas immanent in nervous activity” in the Bulletin of Mathematical Biophysics.
The paper, in which they discussed networks of idealized and simplified artificial “neurons” and how they might perform simple logical functions, became the inspiration for computer-based “neural networks” (later renamed “deep learning”) and their popular description as “mimicking the brain.”
Today, artificial neural networks-based AI programs such as ChatGPT follow McCulloch and Pitts in producing hallucinations.
