7. If a face image is a 100 × 100 image, written in row-major, this is a 10,000-

dimensional vector. If we shift the image one pixel to the right, this will be a very different vector in the 10,000-dimensional space. How can we build face recognizers robust to such distortions?

types of strokes, curvatures, loops, how you make the dots, and so on, that discriminate your handwriting from that of your friend’s.
