Parts 1–3
Slides
CNNs, YOLO, and a step-by-step training guide. Use the arrow keys to move through them, S for speaker notes, Esc for an overview.
Part 4
Training notebook
Train a YOLO11n detector on a 4-class wildlife dataset, read the results, look at predictions, and find the failures. Shown here with saved outputs.
What's covered
- What is a CNN? Images as numbers, filters and feature maps, layers, how learning works
- YOLO. Detection vs classification, grid prediction, backbone/neck/head, IoU, NMS, model sizes, transfer learning
- Training, practically. Collecting and labelling data, splits, training, reading curves and metrics, augmentation, troubleshooting
- Live notebook. Train a model end to end and inspect its predictions
