Early Spring Bloominghack!

Tuesday, March 23rd, 2010

– Alex is porting the rhyme-scoring code from the poetrybot to Python
– but right now, it only does end rhymes, which isn’t particularly interesting. (but it’d be pretty easy to expand to internal rhymes…)
– in research news, he plugged toulbar2 into the dependency parser (which uses constraint solving to do a parse — and now pretty soon will do “soft constraints”, or just “preferences”) — and is now thinking about how to find out what the weights on the constraints should be, with machine learning.

– Lindsey read about information flow security in a PL context (so, like: languages that support security levels in the type system. eg: jif)
– also: went running
– research news: working on translating a language with dependent types to continuation-passing style. Also, thinking about how to formally describe (like, with automated theorem-proving) the interactions between static and dynamic languages.

Tuesday, January 13th, 2009

Nirmal (Patel) is here!
Telling us about his research and trips to Korea for a project.
He’s been reading for quals.

Alex is hacking Haskell, doing the Accordian problem.
Doing IO.
Working on chapter 4 of Real World Haskell.

Rob is scheduling a Martial Arts Movie Party.

01 May 2007 – atlhack, your connection machine

met AJ, grading papers – grading papers for intro to MBA at UPhoenix. "Born to Party" t-shirts

Sonali means like Gold! Tejus means bright like the sun!
Graham’s name means "gravel area" or "grey homestead".
Mark means a dot on a plot or visualization. Will means great protector.

Since Last Week-
Will- job search stuff, met with Coke people. debugged BASIC for running beverage dispenser, with a Y2K bug, doesn’t deal with the midnight wrap. now it uses millisec since 1901.
-finished with reading Jason’s entrepreneuring books.
Mark- made bricks in nodebox. wants to make cornered bricks.
-doing visualization for high dimensional dataset.
-was chased by a Jeep and slammed his finger in a door.
-met Jay Jackson, a Qaboomer, starting brewpot.com
Tejus and Sonali- got highlights in their hair.

Mark likes Mira Nair imdb wp documentaries and dramas, movies about Bombay street kids.

Graham
-loves Mark Guzdial’s blog on CS education- GOTO considered useful for learning.
John Maeda – artist at media lab – advisor to Processing. He used to write programs without loops.
Functional languages do not perhaps support the tracing-through metaphor of languages.

Senior Seminar / Final Quarter Chapter 1

Friday, January 19th, 2007

Hello everyone. I’m Mike. I’m studying mathematics at University of California at Santa Cruz. This is my last quarter and I have a talk that I have to give, and a senior project that I have to do.  The idea of these posts will be to track my progress on this project, and my progress in my other classes. I hope that this will help motivate me to do my very best in my last year in university.

Here is the class rundown in order of difficulty:
   Senior Seminar
   Real Analysis
   Latin 2
 
Here is the broad view:
   Senior Seminar:
       Give a 35 minute talk on a mathematical topic, on February 7th
       Turn in a 10 page paper on the topic by the end of the quarter.

    Real Analysis:  
       Weekly homework. Due Wednesdays.
       Reading.
       Tests.

    Latin 2:
       Homework for class 3 times a week.
       Reading.
       Tests.

Listing these is already starting to make things feel more manageable.

Now for some more details on my Senior Seminar:
    I want to study polyphonic source separation algorithms. Through what little research I have done so far I have realized that this is too broad a topic to fit into a 35 minute talk. So, my first task is to narrow down what I will talk about. As it stands right now, maybe a short talk on the Discrete Fourier Transform would be good. Right now, the basic structure might go something like this:

1. Explain in broad terms how digital audio works.  Samples, sampling frequency, possibly the sampling theorem, Nyquist frequency, etc.
2. Explain the mathematics of the Discrete Fourier Transform. Maybe, talk about the Fourier Transforms uses in other branches of math and science.
3. Explain what polyphonic source separation is, and how the Fourier Transform is used as a tool in polyphonic source separation algorithms.

    Somewhere in there I want to talk about psycoacoustics, and cognitive science, but maybe there is not enough time to do that and I will have to save it for the paper.

In conclusion I will leave a list of things that I need to do in the following week:
    Senior Seminar:
       Continue reading Tuomas Virtanen‘s thesis on polyphonic source separation.
       Write a possible outline, and bring it to my professor on Monday.

    Real Analysis:
       Complete homework assignment. Do at least 1 problem every day.
       Finish reading chapter 1. Begin Chapter 2.

    Latin:
       Catch up on backlogged homework. (Tomorrow!)
       Stay caught up. Do a little every day.

Next time I will review my accomplishments, and I will describe a technique developed by my parents to help get ideas down on paper.

-Mike
