15.6 The ‘deep’ in deep learning (3)
- Q: What is illustrated in Figure 15.3?

Figure 15.3: Deep representations learned by a digit-classification model (Chollet & Allaire, 2018, Fig. 1.6)
- Network transforms the digit image into representations that are…
- increasingly different from the original image (going from layer to layer)
- increasingly informative about the final result
- Deep network = multistage information-distillation operation
- Information goes through successive filters and comes out increasingly purified (that is, useful with regard to some task)
- Deep learning (technically): a multistage way to learn data representations
