โ€ข Next, Pooling layers reduce the spatial dimensions while preserving important information. โ€ข Then, fully connected layers take these extracted features and make final classifications by weighting connections between all neurons.

Fukushima's video (1986) shows a CNN that recognises handwritten digits [3], three years before LeCun's video (1989). CNN timeline taken from [5]: โ˜… 1969: Kunihiko Fukushima published rectified linear units or ReLUs [1] which are now extensively used in CNNs. โ˜… 1979: Fukushima published the basic CNN architecture with convolution layers and downsampling layers [2]. He called it neocognitron. It was trained by unsupervised learning rules. Compute was 100 times more expensive than in 1989, and a billion times more expensive than today. โ˜… 1986: Fukushima's video on recognising hand-written digits [3]. โ˜… 1988: Wei Zhang et al had the first "modern" 2-dimensional CNN trained by backpropagation, and also applied it to character recognition [4]. Compute was about 10 million times more expensive than today. โ˜… 1989-: later work by others [5]. REFERENCES (more in [5]) [1] K. Fukushima (1969).
