In page Marvin Minsky:

"

Minsky and Papert's book Perceptrons attacked the work of Frank Rosenblatt on Perceptrons and became the foundational work in the analysis of artificial neural networks. The book is the center of a controversy in the history of AI, as some claim it greatly discouraged research on neural networks in the 1970s and contributed to the so-called "AI winter".[4] Minsky also developed several other AI models.[citation needed] His paper, "A Framework for Representing Knowledge,"[5] created a new paradigm in knowledge representation.[citation needed] Perceptrons is now viewed as being more of historical rather than practical interest, but his theory of frames was, as of 1975, in wide use.[citation needed][6]
