Ch 16. Visual recognition models
Successful models based on deep convolutional neural networks (CNNs) but early models required supervised learning and very data dense input
More modern models are data lean (representing objects with the smallest most efficient means) and use unsupervised training methods. They are very good

Emotions have both physiologic and cognitive components.
