Hi all,

I’m Nate. In 2001, I graduated from here with a degree in Comp Sci. Afterwards, I spent a few years working at the Health Sciences Library, and a few years working at Wendt Library, gradually transitioning from a desktop support person to a web developer. Since then, I’ve moved to a brain imaging lab and now help build tools for scientists to use mainly in functional MRI studies. And in my spare time, I’m a co-founder of a small startup company, where we sell software for librarians to help in running and staffing a reference desk.

As far as my interest in vis goes, I’m very interested in learning to make tools for our researchers to better explore fMRI data — existing tools are of really low quality. I suppose this puts me on the midline between domain scientist and designer: I’m not going to discover any new principles of visualization, but I sure would like to learn to make better tools.

Skillset-wise, I have about 15 years of programming experience in various languages, though in recent times, I’ve gravitated towards dynamic-ish languages — ruby and python are favorites, depending on what needs to be done. I actually like javascript. I’m quite light on graphic and interaction design skills; I really don’t feel like I’ve ever made anything really beautiful, or with a particularly elegant interface.

And here is a picture of me, from when I became married.

Interests? My interests lie mainly in interdisciplinarity and cognitive science. I have particularly enjoyed learning about graphics and visualization (which is why I’m here).

Since I’m interested in visualization as a science and I don’t have a specific “domain” to apply it to, I guess I would fall somewhere near the Vis Scientist category.

Expectations? My expectation for this class is to learn about the scientific rigor applied to a field that I have previously thought of as being guided primarily by subjective principles.

Skills? I came here last semester knowing Matlab, and have since learned C++ in what could best be described as a baptism by fire.

I’m a first year grad student in the CS department working towards a masters degree.

Before coming to Madison I received my Bachelors degree in computer engineering from MSOE and worked for about three years after that. Highlights of my career include working on embedded systems with PIC microprocessors, doing data analysis and later quantitative trading for a hedge fund, and controlling printer finishing equipment at Quad/Tech.

After all of that, I decided that I wanted to work in the computer animation industry and so I applied to Madison to focus on computer graphic for a few years before diving in.  I’m interested in pretty much anything that has to do with computer animations including modeling, rendering, and animating.

I’m interested in the vis class because there is an awful lot of information to visualize when dealing with all aspects of computer animation.  A big part of the animation industry is now bringing down costs and making production processes quicker.  Better methods of visualization could be key to this task.

I’m also interested in vis from an educational stand point.  I good visualization can mean the difference between leaning a complicated subject or being completely overwhelmed by it.  I’m interested in any methods of making difficult subjects such as transient analysis of linear circuits easier to understand through good visuals.

From that description, I would say that I fall between vis science and domain science.  As far as my expectations for the course go, I would like to see some of the interested ideas I’ve had for visualizing circuits and math problems come to light as small projects.  I’d also like to get an idea of what “works” in terms of visualizing different types of data.

My skill sets pretty much include C++/C and Java for programming languages and a decent ability to to work spacially.  I’ve done some work with web development inclucing php and database work although I don’t consider myself a pro.  Durring my down time I like to play the guitar and drums, draw picturs, watch movies (computer animated) and play video games.

Here’s a picture of me

Unfortunately, I don’t have a personal website that’s worth looking.

  • Emma Turetsky
  • Department: Computer Sciences
  • 1st year grad student
  • My interests are in PL and Graphics (varied, I know.)  I have a strong interest in various ways of turning 2D v0lumetric data into 3D images, specifically in brain scans.  I suppose I see myself as a Vis Scientist (I wasn’t in class, so I don’t know the specifics of the different perspectives), but I want to make tools to better visualize data, so maybe a designer as well.
  • I hope to learn what makes a “good” visualization versus a “bad” one.  And maybe learn techniques that are used to make visualizations.
  • I’m confident in Java and C++ as well as Scheme and other ML like languages.  I also have a background in Prolog if that would at all be useful.

    Visualization resources

    Just found this huge list (of lists) on  nice data visualizations. I think some browsing around those resources could be quite helpful to get some ideas on the ‘design’ side of the triangle spectrum.

    Also, this blog delivers a lot of issues and information on information visualisation.

    This week in 838 (Jan 25-29)

    in News

    For Tuesday, Jan 26, there is a reading assignment and a writing assignment (your biography). We’ll talk about the ideas about the basics of visualization, and use the class as a chance to get to know each other a bit.

    For Thursday, Jan 28, there is another assignment to get a sense of what is going on in the field of Vis research. In class, we’ll talk about the various things that are “hot topics”, and use a conversation about what is interesting to each of us as a way to get to know one another.

    And soon, there will be a syllabus that looks more than 1 week ahead 🙂

    assignment due Thursday, January 28th (please post your comments before 9am so we can read them before class)

    The goal of this assignment is to give you an idea of what is going on in “Visualization Research” as a Computer Science Discipline. This is only one perspective on visualization, and this will give you a particular slice of it, but its better than nothing.

    The premiere academic venue for Visualization (as a computer science sub-area) is IEEE “VisWeek.” Its a set of 3 conferences that are co-located. The proceedings are published as a special issue of IEEE Transactions on Visualization and Computer Graphics. The event is evolving. Its usually in October.

    The past few years, there’s been 3 events “Vis,” “InfoVis,” and “Vast” (Visual Analytics Science and Technology). The most recent one (2009) was in Atlantic City this past October.

    The goal of this assignment is to give you an idea of what kinds of things go on at this venue (as a way of sampling what “Visualization Research” is.

    Your task is to look through the “proceedings” of the “conference” (really the 3 co-located events) and see what catches your eye. Of course, this being the modern era, you won’t actually look at the printed proceedings (they don’t even give it out at the conference – they give out a USB stick). One down side is that printed proceedings are great to flip through for this kind of purpose, and online proceedings are less skimmable. You don’t need to read the papers, but I want you to get a sense of what kinds of topics are there (and might be interesting to you). If you had the printed proceedings, you could flip through and see what pictures stood out.

    What you should do (the resources for doing this are below):

    1. Look over all the titles, see what catches your eye.
    2. For some subset of those, look a little more closely. Read the abstract, look at the pictures, maybe the author has a website or something…
    3. Pick a few of your favorites. Between 3-5. At least one must come from InfoVis, at least one must come from Vis. Give your list as a comment to this message. Please either remember your list or bring it to class.

    Without the printed proceedings, your resources for doing it:

    • The VGTC website. VGTC is the committee of IEEE that organizes the conferences. They have a great website. For example, at this page you can see a list of all the papers, links to the abstracts, and links to the slides from most of the talks from Vis09. (there’s a similar page for infovis).
    • The graphics papers on the web resource has links for Vis09 and InfoVis09. These are unofficial, but they usually have links to either the author’s web pages or the project web pages, where you can find more info (and even the PDF of the paper).
    • The official digital library page. Most useful to get the actual papers. We have a campus-wide subscription (so either access it with a campus IP address, or use the library’s proxy server).
    • If you’re off campus, you need to access the IEEE DL via a proxy. I think this works.

    All you need to do is add a list of 3-5 papers as a comment to this posting, and come prepared to talk about what you’ve found. Again, I don’t expect you to actually read any complete papers (you are welcome to, but there will be plenty of time for that later in the semester) – but I do want you to get a sense of the range of topics that people are writing about.

    Addendum: the digital library, while inconvenient, is the only real way to get the papers reliably and officially. Many authors put copies of the papers on their personal or group websites, but not everyone (and its unclear with the IEEE copyright agreement if this is a legal thing to do. it is OK with ACM).

    Addendum 2: I understand that the papers people pick will be biased towards those that are convenient to find. There is no notion that this will be an unbiased sampling.

    Reading 2 Updated with Tufte

    January 22, 2010

    in News

    Wendt library has scanned some pieces of Tufte’s books for the class, so I have assigned a chapter as part of Reading 2 for Tuesday. The chapter “Graphics Excellence” is here. This is a good test to make sure you can get at the course protected directory.

    Warning: the scans are very big! (and don’t forget the instructions for the protected course reader)
