4 sections. Section 1 'What Makes It Deep': Multiple hidden layers (50-1000+). Each layer learns increasingly abstract features. Image example: Layer 1 → edges. Layer 2 → shapes. Layer 3 → parts (eyes, ears). Layer 4 → faces. More layers = more complex representations. Section 2 'CNNs (Convolutional
