26th Feb_5th week review

Today is Saturday, not a smooth day.

4-5 week I was quite productive.

4th Sunday I start over with Fei, study some Random Forest theory in Duda book.

On Monday I forgot to finish grading HW before 11am, it was a significant mistake, I should have done the job earlier. And basically I prepared for the Tuesday quiz of Networking in the evening.

On Tuesday I prepared the quiz in the morning, and the quiz turns out to be a funny survey of the course, but at least I know that the first funny quiz only counts for the attendance. In the evening I basically figure out the canny contour detection algorithm and change the Matlab code in the toolbox to get a 18 dimensional shape features of Corel dataset.

On Wednesday I try to figure out how dose wavelet filter work to extract 9 dimensional texture features. And I stay late to 4am before leaving.

On Thursday I prepared for the recitation a little bit, held  the recitation and decided to choose mean, variance and mode number of the three lever of wavelet decomposition coefficient as the 9 dimensional feature at last and left the lab at around 4am.

On Friday I collected the data and presented it to Caiming, who seems quite impressive and decided to use Corel dataset again to see what could happen. And I finished the recitation and graded 50 HW and 50 quizs in the evening. Got home around 12:30.

On Saturday I finished 3 problem of Pattern Recognition HW and try to follow the experiments in the DCA paper. And, talk with Dingcheng and WeiChen provides me some thoughtful and pleasure time. At last, I would like to finish PCA tonight.

19th Feb.

11 months later, in the cold winter of Buffalo, which is just like the cold winter of Tianjin, I got there. But this time I don’t want to keep lightening cigarettes and listening to the busy bee of cellphone; the emotion is not a hurry anxiety any more, but turning out to be a final pressure of months. I have my happiest and saddest life in the past few months, and never regret to say yes in the gloomy spring afternoon.

Take care, fei; take care, ran.

1. How to comprehend the row instead of column/row dot product of 2DPCA in comparison with PCA.

2. Trace of the matrix transform and correspond scatter matrix derived from the trace.

To do:

1. 589 slides update and summary of last lec(with examination problem)

2. summarize 555 Q and ask TA in Fri morning

3. PCA/2DPCA/Kernel PCA/ Robust PCA implementation

4. NS2 tutorial before Tuesday TA office hour

15th Feb

For NS2 project:

Find some demo, code the C file in “mac” and replace some, and add them into the proper library, add .o file into makefile and run it to test.

timberlake {~/589/ns-allinone-2.34/ns-2.34} > ./ns /usr/share/tk8.4/demos/twind.tcl

To upload, it is scp OnlineForest-0.11.tar.gz rxu2@timberlake.cse.buffalo.edu:/home/csgrad/rxu2

To extract, it is timberlake {~/OnlineForest} > tar -xzf OnlineForest-0.11.tar.gz

Skiing Day

So near to the death, so strong feeling around the days, and I believe all these ebbs should be of my great experience.

Thank you, Fei.

Today I come back to normal, attend 2 lectures and lead a recitation. During office hour, I settled a problem of a student and buy a pad from Amazon.

Start working at 7:45pm, late.

Review today’s Random Algorithm by 9pm.

Answer the question of student and go over whitening transform by 9:30pm.

Finished part of SVM blog by 11pm.

Spring Festival

Even though not in very good mood, I gonna keep what I have done last night, start working around 12:40pm, turn off the email/website and do the job.

Did few job, finished two articles of Freemind’s blog and sort of got in touch with him.

Prepare for the Spring Festival dinner, dumplings, chicken wings, etc. Birthday dinner of “24”, with warm atmosphere, pretty impressive.

Cold days as Feb. 1st, I attend 3 coures thru noon, eat some subway and rush to the office hour. The course is diving into something serious, and I’m gonna to pay more attention. Hurry up, man.

The afternoon is very unproductive, talk with TA of 555 and 589, hope they can help in case I got in a mess.

Focus on one task, and pay all the attention on it, do not stop to do another task before finish one, do not check email, chat with others, scan the website, or eat.

Do one task until finishing or my body cannot support.

Tonight I gonna again focus on SVM, read one chapter, read the blog and test the code. I finished one chapter when 11pm. Keep working tomorrow.

Other thing I may probably do tomorrow:

1. Prepare for the recitation.

2. Learn latex, complicate a PDF(CVPR template), and a PPT.

3. Convex Optimization
