Barabasi Bursts's Video @ Google Talk

I found another Barabasi's video from Google about Bursts concept. I think that this video is better that the one I posted before, since it has more discussions and it encapsulates the content of the book better. High predictability of social occurences concept that Barabasi has forwarded, relies mostly on big chunk of historical data utilization which now can be operationalized by applying data mining/ machine learning methods.

One main character discussed in the Bursts book is Hasan Elahi. When I tried to search for his videos, I can easily find one. I post one of them which I find interesting. He managed to give the impression that he is not a boring guy :p. It always good to connect a bit more to the characters in the book that I have read. It brings more understanding and more connection to the idea. Nice weekend all..

Cool Lecture Videos: Introduction to Multiagent Systems

I think its really cool that a Professor would spend some time giving lectures which are accessible for everyone by using the web. While studying the multiagent system (MAS) subject, I found a set of lectures uploaded on youtube by one of the Gurus in the MAS, Michael Wooldridge of University of Liverpool. Its just great to feel his enthusiasm in delivering the talk.

If you browse down his youtube channel, you will be able to browse all videos. Starting from video 02-06 the formalization of the MAS discussion starts. The videos with lower serial numbers are more conceptual. It just brilliant. For me learning from videos is more effective, more time efficient, and more fun. You can fast forward the things you already understand, and you can rewind the things that you find difficult to grasp. It is just awesome. I think more lectures should be uploaded more to the internet. Global students should be able to learn from global professors and be mesmerized :p Anyway, I embed also an interesting video uploaded by Prof. Wooldridge. Enjoy :)

Hans's Thesis Review

Since in the near future, I will conduct a Multi Agent Systems (MAS) based research in the container terminal domain, I read Hans's thesis as part of my literatures review. He developed MAS based Decision Support Systems (DSSs), each for transportation load allocation case and barge rotation case. Personally, Hans put the strong emphasis on the "real time" benefit of using MAS-DSS instead of centralized DSS. The flexibility and the robustness of MAS DSS in coping with real time disruptions are the main points.

The thesis reflects intense communications between the researchers and the practitioners. I think the narration could have been worked a bit more so that the thesis could be digested better. Well just a personal thought though, its a great work anyway..

Coordination: Challenges & Enhancement Proposals

1. Cost and benefits unbalanced load
2. Low motivation
3. Strategic considerations of the members
4. Lack of dominant firm
5. Risk aversion attitude
6. Short-term benefit rather than long-term benefit orientation

Enhancement Proposals:
1. Incentives introduction
2. Inter-firm alliances creation
3. Scope resizing
4. Collective action creation.

Lessons Learned from Bursts...

Randomness is disputed ...

Prioritization is the key ...

Bursts forward the generalizability of occurences ...

Personally, I don't like the lengthy crusades stories though ...

Live a Passionate Life ...

"People say...
You have to have a lot of passion for what you are doing...
and it is totally true...

and the reason is...
because it’s so hard, that if you don’t...
any rational person would give up...

Its really hard...
and you have to do it over a sustain period of time...

So if you don’t love it..
If you’re not having fun doing it...
you don’t really love it...
you’re gonna give up...
and that’s what happens to most of the people actually..."

Livin' On A Prayer ...

"We've got to hold on to what we've got
'Cause it doesn't make a difference
If we make it or not
We've got each other and that's a lot
For love - we'll give it a shot"

"We're half way there
Livin' on a prayer
Take my hand and we'll make it - I swear
Livin' on a prayer"

-Livin' on a Prayer by Bon Jovi-
