8.6 The ‘deep’ in deep learning (3)

  • Q: What is illustrated in Figure 8.3?
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
