Perceptrons: the limits of a single layer
Marvin Minsky and Seymour Papert published a mathematical analysis of what a perceptron can and cannot do.
Why it matters
The book established concrete limits of single-layer models. It is often linked to the decline of neural-network research, although it does not claim multilayer learning is impossible.
How far the book affected research funding remains a matter of historical debate.

It refutes the broad reading of the perceptron critique: with a hidden layer the limitation disappears.
