Neat Slideshow on How Social Networking Fits in with Maslow's Hierarchy of Needs

This is a very interesting slideshow, well worth the 4 min it takes to read. I think it gives great insight into where Facebook, Blogging, etc. comes in. In short, people follow Maslow's Hierarchy of Needs in their usage of the internet. They want to feel secure, they want to be able to accomplish their task, then they move into higher needs like the need to be social (enter facebook blogging, chatting, etc).

Anyway, it gives a good perspective on where these technologies fit in.

DML Weekly Report

1. What you have done
* Helped Yao with his rough draft, get into our code base, etc.
* Discovered how to use weka classes in my code, serialize models, and then reload the models and run "production" tests/questions on it.
* Found 5 papers related to our 3 papers
* Wrote a lot of code

2. What problems you have encountered
* I am struggling to understand how to get probability scores out of a classifier. For example, if I train a boolean classifier, I want it to output a score between 0 and 1 instead of just o or 1 so I can do my own threasholding.

* I (as always) need a day or two more to get you a rough draft of my paper, and then another week or two to start getting results.

3. What possible solutions you are considering for these problems
* I'll ask you about the first and the second.... well just throw myself upon your good graces yet again....

4. What you plan on doing in the coming week
* Work more on media items for HS presentation (video)
* Finish my abstract, help Graham finish his, get probability scores out of weka, finish fast evaluation system.


5. New ideas, specific topics/issues you wish or us to focus on in
I need to be able to get out of a NN, or Decision tree a probability score (even on new instances) rather than a Y/N answer/class.

DML Weekly Report

1. What you have done
* Worked with getting Graham started on an unsupervised learner. Talked to an MS stat student about our assumptions.
* Worked with Yao on working just for a few weeks with us on Record Linkage and comparing metrics. Showed him our code.
* Worked on converting everything to use weka instead of Clementine.
* Met with the department about presenting to high schools.
* Began working on my media items for the High School video presentation.
* Helped Jun for a number of hours on his lab related stuff.

2. What problems you have encountered
* Keep crashing weka even with a 1.5gb jvm.

3. What possible solutions you are considering for these problems
* I am going to call weka classes from my program to decrease overhead.

4. What you plan on doing in the coming week
* Work on media items for HS presentation (video)
* Integrate an evaluation system into existing code using weka (to speed iterations)
* Help Graham, Yao, and Jun


5. New ideas, specific topics/issues you wish or us to focus on in
Does any one have clementine I could use for just one hour?
