Exhibit 2.1
1969The limits of the perceptron
Minsky and Papert show mathematically that a simple perceptron cannot solve some basic classes of problems. Research on neural networks then loses momentum for years.

Why it is in the museum
Progress was not continuous. Periods of great expectations were followed by technical limits, disappointment and cuts in funding.
What supports this exhibit
Primary technical monograph
The mathematical analysis of limitations of single-layer perceptrons.
Main source: Minsky, M. & Papert, S. (1969), Perceptrons, MIT Press.
What to keep in mind: Primary technical source; its connection with later funding decline is a historical interpretation.
