A verbose 4th of July morning...

It seems like blogging is becoming less popular after mobile revolution. Interesting, now we have so many ways to write and so many apps to write with, but it became less popular. Or maybe it just me, start writing blog after few months and feel like everybody is doing the same. Anyway, happy 4th of July everyone.

I was browsing woot.com this morning and at the bottom of the page it ask for a survey. And the question was what is the best part of 4th of July? Fireworks? Day off? And few other things. I guess its day off for me now. Its always fun to have one extra day off.

I feel like I am writing after a long time. Blogging has always been fun for me. But nowadays it is hard to find things to blog about. So, I stopped writing. I am going thru that part of the life when nothing happens other than ageing. Sometime I feel like this will continue for some years and at some point I will realize I am an old man now. I have lived my life. I will start giving advise. It surprising human that most of the human lifes are utterly similar. Among all the diversity and friction we see among human being, they are just ridiculously shallow. Deep down inside we all are same. Not biologically but mentally and how we live our life.

Life is the most amazing thing I have. It always surprises me like it surprises rest of the 7 billion people on earth. After all these surprises I don't understand how come they are same? Is not it amazing!

Well enough of stupid rumblings. I am gonna go ant watch the stupid Germany vs France game. This will be the first time I will cheer for France. Hope they will be able to pull it forward.

Higher dimension!

I was trying to extend my outlier detection technique for higher dimensions. I kept the basic same and try to distinguish outliers in higher dimension. My original technique was based on nearest neighbor and I figure out my approach is not working for higher dimension very well :( I went deep into the program and trying to figure out 'why?' Eventually I realized the average density within certain radius is not very different than the average density of an outlier! In brief the distance is not a discriminative feature of an outlier!

I look into the dataset and it looks okay, then I look into the literature and found something equally interesting and horrifying :( nearest neighbor for higher dimension is not very meaningful; for high dimensional data the ratio of the distance to the nearest neighbor to the distance to the furthest neighbor is 1 and therefore the nearest neighbor based discrimination is not fruitful at all! The situation may improve if we change the distance metric from euclidean to manhattan but not full proof! The good thing about this result is all distance based outlier detection is use less for higher dimension but the bad things is mine is also use less! I have to look for something very different than nearest neighbor.

It is not very intuitive to visualize higher dimensional space and therefore is not easy to imagine the notion of outliers in higher dimension! I guess I need to figure out about what's work on higher dimension. That would not be a easy journey at all.

iPhone!

Fianlly I got the idea, blogspot doesn't have any app for iPhone but it does have for android. Never mind I ma learning working with web interface. It should b fine until I am planning to embeb picture.

Last few days I am trying to write an application for myself, apprently there is no easy way to write iPhone apps for Linux or windows and I don't have Mac machine :( This is something I really hate about Mac. Diversity is beauty and certainly Apple does not understand that.

New day

Ok, here is a new day. Today I wake up early, way not that early compared to week days, but yes it is early in the morning for Saturday. Lipa is preparing for GRE so we got to wake up early, then had our breakfast and now she is studying. And me, I am blogging. I am trying to be more connected with my blog than ever before. Why I am doing this? Partially this is because I feel like I am kind of detached from and my blog and most importantly, I need someone to share my life. Probably, it's bit difficult share your life with your wife, it's rather easier to share life with blog. Moreover, I got the mobile blogging thing which even more fun.

I believe blogspot should two kind of post, one is like blog and the second category should be very much like twitter; in that case I don't have to go to twitter and I can access it from here. But Google has Google Buzz but they connected Google Buzz with wrong thing, Gmail. Status update with email!!! Is it a kind of joke, I didn't like it, apparently not many people liked either. It was indeed a wrong step but they could do even better if they connected with blogspot. Because blogspot users like to share there life with the world not Gmail users, so in my view they targeted wrong kind of people.

I just finish the Apple's keynote for iPad 2. In my believe this time the big thing they did is made some really cool software to really make iPad popular. I already can see, people are using iPad; most likely they use it for fun nothing so professional and I believe the new apps add even more fun. I kind of live their Garage Band app. It seems really cool! I was kind of skeptical when the first iPad was lunched and still I am, but now I am kind of sure it is a fun box; then my question is how long it going to survive just as a fun gadget, or they have real plan to make it real professional. Let's see. I have already enough for today, good day.
