I had some free time today and watched the soccer game. MU was really good and Arsenal did not make it today. I still insist Arsenal will win in the semifinals. Go Arsenal! Goal! Goal!

Here are about some interesting posts in kdnuggets. List several here.
One is about the performance comparison between the mapreduce and the parallel database. The paper indicated that parallel databases has a better performance than mapreduce. I have not look into that paper, but I guess mapreduce may achieve a better reliability and fault tolerance, and this is the main reason Google deployed it. I will go on to look at this topic.

The other is about a interesting application about the cloud computing. This is about Google again. I have to say I am not a fan of Google, but some of its applications are really interesting and worth trying. Google presented a platform called Google App Engine, where developers can build their own apps on this. If you need more resources (hard disks, cpu cycles...), you can pay Google and get things you need. Current two languages, java and Python are supported. Interesting.

Will cloud computing be the next hotspot in the data mining communities? It might be true when we are talking about the pegabytes of data, where large amount of computing resources are needed. Privacy preservation is an issue in cloud computing. Any way, this trends is worth tracing in the future.

plan 4.28

I took two classes this morning from 8:30-12:00.

1. Today review the 725 homework and solutions.

2. The global trees code writing.

3. Finish the annotation for 788, and read papers about the research project.

Do not be afraid to try new things

I always have a tendency to become narrow-minded. A possible solution is to try new things frequently, talk with friends, appriciate the diversity and learn from differnt people.

plan 4.26

1. finish the 725

2. Finish the annotation in 788 and read papers for the project. ( VLDB paper)

4. Have a nice day! i am glad to meet a new student of our group.

plan 25, I am back

Finally I have my own time and space. Thanks, nice weather.

Today and tomorrow will continue to be busy.

The task for today
1. Finish the English composition. (5)

2. Read the 725 notes, and do half of the homework. (4)

3. The annotation in 788. (3)

4. Read the papers and coding the GT. (2)

5. English 104.5. Read and Write. (5)

I wonder why I leave so much work undone. I will not go home unless I finish the tasks!

Nice day again. I feel very good.

Today I have finished reading several papers on the outliers detection. The KDD'08 paper seems deviant from what I am working on. The SSD staff can be postponed due to the lack of clear research plans. I have gone over the basic Latex and I still need more practice on that. The Openoffice is not easy to use to me. In the future I will use the latex more frequently.

I noticed some changes on myself which really made me happy. I am more willing to exchange research ideas with others, which is partly due to Srini's 788. When I met someone, I would try to talk about what he is currently working on and see if there are anything interesting to me. I wish to share the amazing ideas of my friends' research, and let them know why my research is interesting and challenging. In the past, I seldom did this.

Another story I read today was about the famous general in the ancient China. He was too proud of himself and thought himself superior to others. Finally, he got killed... Their are a lot of such Chinese stories which tells us to be humble and respect others. I should learn more from them. Be a humble researcher.

A bad thing is recently I had less time to work on my English and the 725 course study. A balance should be guaranteed between research and class. A better and flexible schedule must be made to reach this goal.

The left work today includes the materials for tomorrow's 104.5, 108 and 788... I have not finished any homework for tomorrow!! Tomorrow will be another busy day, but I am satisfied with my life and hope I can be what I can be.

Enjoying today!

Sports! I really enjoy it!
So tired now. I need to sleep.
