  29. T 12/3: Convolutional Neural Nets. Slides, Sample Problems, Solutions.
  30. R 12/5: Simulated Annealing, Mini-Batch, Data Augmentation. Slides, a video about simulated annealing.
    There is no new theory, in this lecture, that you need for the exam. You don't need to know about simulated annealing, or about mini-batch, or about data augmentation. However, the sample problem only covers (1) forward-prop, (2) knowledge-based design, and (3) back-prop training, so the sample problem is fair game for the exam. Here it is: Sample Problem, Solutions.
  31. T 12/10: Exam 3 Review
