The history of deep learning is a fascinating journey of theoretical breakthroughs, technological advancements, and periods of both excitement and disillusionment. While the term 'deep learning' is relatively recent, the underlying concepts have been around for decades.

Early Days (1940s-1960s):

• 1943: Warren McCulloch and Walter Pitts create a computational model for neural networks, laying the foundation for artificial neural networks.
• 1958: Frank Rosenblatt invents the Perceptron, an algorithm for pattern recognition, sparking initial enthusiasm for neural networks.
• 1969: Marvin Minsky and Seymour Papert publish 'Perceptrons,' highlighting the limitations of single-layer perceptrons and contributing to a decline in neural network research (the 'AI Winter').

The Revival (1980s-1990s):

• 1986: Geoffrey Hinton, David Rumelhart, and Ronald Williams popularize the backpropagation algorithm, enabling the training of multi-layer neural networks.
