Intermediate Topic 33 of 51 AI & Machine Learning

Convolutional Neural Networks

Networks using shared filters for images.

How it works

CNNs slide small learned filters over images, sharing weights and capturing local patterns, with pooling and hierarchical features (edges → shapes → objects). ResNets add skip connections.

Where it is used

Image classification, medical imaging.

Common pitfall

Not inherently rotation or scale invariant; augment data.

Where it fits in the course

Convolutional Neural Networks is topic 33 of 51 in AI & Machine Learning, rated Intermediate. It follows Backpropagation. The next topic is Recurrent Neural Networks.
