- The Main Problem: Semantic Gap(to computer, it’s just a gigantic grid(matrix) of numbers)
- Visual recognition algorithm must be robust with
- Lighting conditions
- Location of camera
- Brightness
- Deformation
- Occlusion
- Background
- Intraclass variation
- Various labels
- Data-driven approach: Train bunch of data, then predict given test data for pre-knowledge from train data
- Nearest Neighbor
- K-Nearest Neighbor
