Pastoral idealism

I started reading Leo Marx's The Machine in the Garden - Technology and the Pastoral Ideal in America.

I like this quote from Freund describing fantasy, and am quoting it from the book:

The creating of the mental domain of phantasy has a complete counterpart in the establishment of "reservations" and "nature-parks" in places where the inroads of agriculture, traffic, or industry threaten to change ... the earth rapidly into something unrecognizable. The "reservation" is to maintain the old condition of things which has been regretfully sacrificed to necessity everywhere else; there everything may grow and spread as it pleases, including what is useless and even what is harmful. The mental realm of phantasy is also such a reservation reclaimed from the encroaches of the reality principle.

CVPR 2010

I am in San Francisco right now for CVPR 2010. I was planning on writing up something on some of the interesting papers that I have seen here, but the conference has been keeping me extremely busy. Maybe I will write something up once I leave for home tomorrow afternoon. To summarize my experiences so far, CVPR started out not that exciting but in the last two to three days I have seen some excellent work. I am looking forward to this afternoon session on sparse coding.

How machine learners go for lunch?

This is how my friend, a machine learner, uncertain about where to go and get lunch from decided to settle the problem:

"...random walk on campus, with a bias towards the food courts."

$\textstyle \pi$ Day

Happy $\textstyle \pi$ Day!!

Another computer vision paper

Here is the paper that we are discussing this week at our computer vision seminar. This is work by Kolmogorov, Vicente and Rother on jointly optimizing segmentation and image appearance models using a MAP-MRF formulation.

Computer vision papers

Here are two computer vision papers you might find interesting:

• S Gould, T Gao, and D Kollar. Region-based Segmentation and Object Detection. NIPS 2009.
• C Gu, J Lim, P Arbelaez, and J Malik. Recognition using regions. CVPR 2009.

We are looking at these two papers in our computer vision reading seminar this week.

Learning compressed sensing

If you are interested in compressive sensing and machine learning, this is a very interesting paper that my advisor emailed me. It paints a good picture of how PCA and random projections can be thought to relate to each other. Here's the link.

Hot new machine!

I just got a new workstation today - an Intel Xeon machine, with 12Gb of RAM! Well, I didn't get the monitor yet since, for some reason, Dell decided not to ship everything together, but I had an extra monitor lying around that I can use temporarily. Now I can play around with that 1Gb size training matrix for one of my research projects. I just got Ubuntu 9.10 on it in the evening, after my midterm that didn't go so well, and a two hour long seminar class. I think I might need some desk rearrangement once the ordered monitor arrives.

"Write Blog"

I have to apologize for not being regular. It has been really long since the last time I wrote; things have been pretty busy, with research projects, full load of classes, grading, and all the usuals of being a graduate student. I have been able to attend a number of great machine learning talks as well, which I was planning to write something about, but just never got around to doing that.

I think I really need to put 'write blog' in my calendar.

Getting back to research after break

The winter quarter started a week ago. I have my classes pretty much figured out at this point; now I am trying to catch up on my research from where I left off before break. As I am ruffling through my messy notes, I realize going on break suddenly made all my research projects seem very distant. But, on a good note, I am getting back on track again.
