“Functional Programming for optimization problems in Big Data” by Paco Nathan.
Interesting slide deck, even if it doesn’t start with high drama. 
Covers:
- Data Science
- Functional Programming
- Workflow Abstraction
- Typical Use Cases
- Open Data Example
The reading list mentioned in these slides makes a nice self-review course in data science.
The Open Data Example is for Palo Alto but you can substitute a city with open data closer to home.
