- 4. The University of Washington eScience Institute • Rationale – The exponential increase in sensors is transitioning all fields of science and engineering from data-poor to data-rich – As a result, the techniques and technologies of data science must be widely practiced and widely adopted • Mission – Advance the forefront of research both in modern data science techniques and technologies, and in the fields that depend upon them • Strategy – Provide an umbrella organization for Big Data activities at UW and beyond (new curricula, collaborations, funding sources, hiring practices) – Bootstrap a national network of partners and peer institutes – Attract, develop, and retain “Pi-shaped people” 8/7/2013 Bill Howe, UW 4

- 15. 8/7/2013 Bill Howe, UW 15 matrices and linear algebra? relations and relational algebra? objects and methods? files and scripts? data frames and functions? What are the abstractions of data science? tools abstr.
- 16. 16 Data Access Hitting a Wall Current practice based on data download (FTP/GREP) Will not scale to the datasets of tomorrow • You can GREP 1 MB in a second • You can GREP 1 GB in a minute • You can GREP 1 TB in 2 days • You can GREP 1 PB in 3 years. • Oh!, and 1PB ~5,000 disks • At some point you need indices to limit search parallel data search and analysis • This is where databases can help • You can FTP 1 MB in 1 sec • You can FTP 1 GB / min (~1$) • … 2 days and 1K$ • … 3 years and 1M$ desk cloud [slide src: Jim Gray]
- 17. US faces shortage of 140,000 to 190,000 people “with deep analytical skills, as well as 1.5 million managers and analysts with the know-how to use the analysis of big data to make effective decisions.” 8/7/2013 Bill Howe, UW 17 --Mckinsey Global Institute hackers analysts
- 18. Three types of tasks: 8/7/2013 Bill Howe, UW 18 1) Preparing to run a model 2) Running the model 3) Interpreting the results Gathering, cleaning, integrating, restructuring, transforming, loading, filtering, deleting, combining, merging, verifying, extracting, shaping, massaging “80% of the work” -- Aaron Kimball “The other 80% of the work” -- Aaron Kimball structs stats

- 20. New Phd Track: “Big Data U” • Open to all departments • New courses to “level the playing field” – “Molecular Biology for Computer Scientists” offered this Fall • Dual advising in two disciplines • Joint projects leading to multiple theses – Each methods thesis will include domain impact component – Each domain thesis will include methods impact component • Contribution to a shared cyberinfrastructure – Software engineering experience as a side effect • “Application Assistantships” – Like RAs and TAs; focused on solving a concrete problem 8/7/2013 Bill Howe, UW 20 Magda Balazinska Carlos Guestrin

Three Activities • Massively Open Online Course • New Phd Tracks in Big Data • An Incubator for Data Science • Other actitivites I won’t discuss – Undergraduate “Data Wizardry” Courses – 2-day Bootcamps in Python, SQL, GitHub, … – Certificate Programs in Data Science – Hackathons 8/7/2013 Bill Howe, UW 21
- 22. Data Science Incubator: Motivation • We need the right people – We produce “builders,” but 99% of them go to industry to “make people click on ads” – They aren’t motivated by writing papers – No viable career path in the academy • We need the right processes – Hands-on, extended, intensive experience is required to produce π-shaped people – Data-driven discovery requires intensive collaboration 8/7/2013 Bill Howe, UW 22
- 23. Science Domains Stats, Computer Science, Applied Math • “Where’s the funding?” • “How does this help me write a paper in my field”? • Thin collaborations; nobody to work on the short- term, high-risk, high-impact “triage” projects • “Does method X work on dataset Y?”
- 24. Domain Labs Research Programmers • Expensive; doesn’t scale • “Code Monkey” – No viable career path • Can’t attract top people • No sharing, no community, no cross-pollination
- 25. Data Science Incubator: Structure • Recruit top-flight data science talent • Give them autonomy to select collaborations and projects • Promote them according to “altmetrics” and project impact – “Data Scientist” “Senior Data Scientist” “Technical Fellow” – “Data Science Fellows” • Perhaps non-tenure, but 3-5 year commitments • Funded with contributions from Academic units, IT, Libraries, and soft money 8/7/2013 Bill Howe, UW 25
- 26. Data Science Incubator: Seed Grants • Domain researchers submit Seed Grant applications for short, intensive 1-6 month projects – Reviewed by the Data Scientists themselves • Awardees send 1+ students, postdocs, staff, or faculty to come and physically sit in the incubator space X days per week for the project duration – Application may or may not include funding for the student 8/7/2013 Bill Howe, UW 26
- 27. Domain Labs Incubator • Data Scientists have their own identity and prestige • Cross-pollination between disciplines • Awardees leave with skills and knowledge; become “disciples”

Notas del editor
- Observe the world vs. Observe the dataInstruments vs. Algorithms
- So in part as an attempt to relate “eSciene” and “data science,” and in part to make sure the idea of data science wasn’t completely taken over by the machine learning people, we ran a massively open online course last Spring called Introduction to Data ScienceWe taught Scalable Databases, MapReduce, Statistics, Machine Learning, Visualization
- “Data Jujitsu”“Data Wrangling”“Data Munging”
- Our collaborators tell us that loading data into memory with R is the major bottleneck.It actually changes the science they can do:I would say that we can start answering questions about macro-ecology (study of relationships between organisms and their environment at large spatial scales).
