Computational Data Science. We'll come back to what that is.
Course web site: in CourSys,
My online instruction plan: change as little as possible from in-person offerings.
Lectures will be pre-recorded.
In the lecture time, they will be available as a
YouTube Premier (≈ watch party) in ≈50 minute chunks. Greg will be available in YouTube chat to answer questions during that time.
They will be available as regular YouTube videos for viewing later.
Requirements for you:
Due Fridays. My goal: make sure you actually try out the things we have talked about and see the reality of applying them.
Will contain some short problems to get you used to the tools, expanding to something a more interesting
In the lectures/exercises, I intend to explore what I consider the
core of data science.
The project will let you integrate those techniques, and explore ideas on the edges of that, depending what interests you.
I will (hope to?) post project topic options related to topics like…
Or if you have something else in mind, we can discuss it.
A few details:
Quizzes: 5% each. Dates may change if necessary, but planned during lecture times:
Final Quiz: whenever our
final exam is scheduled.
Instructor: Greg Baker <email@example.com>.
Office hour: Thursdays 13:00–14:00 by video conference and discussion forum.
Office hours: details later.
lectures as expected.
Fridays: usually no
lectures. The TAs and I will all be available for consultation during the lecture time in discussion forum and video chat, mostly for the weekly exercises.
Possible reference material:
Possible reference material (continued):
Python 3 will be the primary programming language language used in the course. If you aren't comfortable with it, you need to be (very) soon.
StackExchange Data Science tags (as of April 2021):
This will be a programming-heavy course. If you don't really like programming, this might not be the course for you.
The programming style will be very library-heavy, which is realistic in the modern world. We will use many libraries: NumPy, Pandas, matplotlib, scikit-learn, statsmodels, ….
That means you'll spend a lot of time reading the docs and fighting to make the tools do what you want them to, and less implementing the logic yourself. That's also realistic.
The code you would have written would almost certainly have been slower and worse.
I will feel free to increase the amount of assignment work a little from my usual level because of the
missing hour of lecture.
To get credit for this course, I expect you to demonstrate that you know how to use programming techniques to manipulate and analyse data. That means:
Failure to do these may result in failing the course.
Academic Honesty: it's important, as always.
If you're using an online source, leave a comment.

That's all I ask, but remember to do it.
You are expected to do the work in this course yourself (or as a group for the project).
Independent work is not copying a solution from somewhere but understanding it. If you work with another student, we shouldn't be able to tell from the results.
More details on course web site.
The quizzes are structured as regular tests: individual work, but open book.
It will be hard to monitor that, but cheating on our quizzes will be treated as equivalent to cheating on an in-person exam, with corresponding penalties: I will be asking for a grade of FD in the course for any academic dishonesty on quizzes.
Computational Data Science: data science, but with computation as the focus.
But what is data science?
According to Wikipedia:
an interdisciplinary field about processes and systems to extract knowledge or insights from data in various forms…
According to Pat Hanrahan, Tableau Software:
[The combination of] business knowledge, analytical skills, and computer science.
According to Daniel Tunkelang, LinkedIn:
[The ability to] obtain, scrub, explore, model and interpret data, blending hacking, statistics and machine learning.
According to Joel Grus:
There's a joke that says a data scientist is someone who knows more statistics than a computer scientist and more computer science than a statistician.… We'll says that a data scientist is someone who extracts insights from messy data.
According to Drew Conway, Alluvium:
data science suddenly so popular?
There's more data being collected: web access logs, purchase history, click-through rates, location history, sensor data, ….
Sometimes the volume of data is big: too big to manage easily. That's where
big data starts.
People want answers/insights from that data: Is the marketing campaign working? Is the UI actually usable? What if we did X instead of Y?
New techniques: Machine learning lets us attack questions that were previously unanswerable. Computer scientists are realizing that statistics is important; statisticians are realizing that computer science is important.
where do we find data?
it turns out that stats course was useful.
it's like AI, except it works.
