For AlexNet, draw a sequence of convolution/pooling stages followed by dense layers and classifier. For Inception, draw four parallel branches and a channel-concatenation join. For ResNet, draw one transformation branch and one shortcut meeting at a plus sign. For transfer learning, draw frozen pretrained base → new trainable head, then mark selected base layers optionally unfrozen for fine-tuning.
Draw the sequential path, parallel branches or additive shortcut that explains the architecture. Tap the diagram to enlarge.
