- 20 What is machine learning and deep learning?
- 21 Machine learning ML: A new kind of science
- 22 Talk overview
- 23 Part 1 - Mathematical formalization of Machine Learning ML
- 24 Old Idea: Curve fitting Legendre, Gauss, c. 1800
- 25 Example: Learning to score reviews
- 26 Example: Learning to rate reviews contd
- 27 ML ~ finding suitable function "model" given examples of desired input/output behavior
- 28 Formal framework
- 29 Training via Gradient Descent "natural algorithm"
- 30 Subcase: deep learning* deep models = "multilayered"
- 31 Summary so far:
- 32 Unsupervised learning no human-supplied labels

- 37 Part 3 - Toward mathematical understanding of Deep Learning
- 38 Special case: deep learning deep = "multilayered"
- 39 Some key questions
- 40 Analysis of optimization
- 41 Black box analysis sketch
- 42 More about optimization in next talk, including recent works using trajectory analysis for gradient descent
- 43 Why no overfitting?
- 44 Part 4 - Taking stock, wrapping up
- 45 1. Imitation approach has not worked well in the past: airplanes, chess/go etc.
