Expository Machine Learning talks at Berkeley Lab:
In July and August 2017 I led an introductory learning seminar in Machine Learning at Berkeley Lab.
The majority of the material that we covered was based on the slides and literature for this Stanford
class.
Some additional materials I prepared for the convenience of presentation:
 Unsupervised learning techniques: beyond clustering and PCA

Slides
 Regularizations in linear regression: ridge, lasso, bridge, elastic net etc
