Principal Component Analysis

I was just looking for some information on ISOMAP . I had then hit by the terms PCA and MDA a multiple times that i decided to give it a good glance . Though i am looking for somehting on machine learning , currently i am into a work with one of my professors who wants to implement AI into some kind of pattern recognition in flow cytometry.

So I have started looking at these topics and i am really amazed at the statistics involved in pattern recognition. So i just give a link here to a tutorial that provides a very clear explanation about PCA method of reduction of high dimentional data.

Hope it amuses some of you too

Share Internet connection in a network – Part 2

By now you must have completed the intial setup as described in part 1
A) On the host computer

1) Goto : Start > Settings > Control pannel

2) Click on ‘Network Connections’
3) Right Click ‘Local Are Connection’ and click on properties.

4) In the ‘General Tab’ Select from ‘This connection uses the following items’
Select ‘Internet Protocol TCP/IP’ and click properties.

5) In the properties window fill the following ip configurations and click ok

B) On the Client Computer

1) Repeat steps 1 to 5
2) In stpe 5 change the ip address to : 192.168.0.2
3) Change the Default gateway to : 192.168.0.1

By doing this your client computer will connect to the internet with the default gateway of 192.168.0.1 which is your host computer.

Robotics India Forum hacked

Robotics india is one good high traffic sites that talk about robotics.it is a sad state to see it hacked . I don’t know since when this had occurred but i saw it today and was pretty surprised to see the note be the hacker saying “Site hacked by damascus”

A good googling will give you information about this new genere of hackers who have set to disrupt the websites around the world.

This is what the forum looked like : Click to enloage

Winning Micromouse Contest

Any robotic contest is NOT “Contest specific” . WHAT?? well i mean to say a micromouse is still a micromouse wether its held at Newyork or in japan or at Anna UniversityChennai .

I felt pretty happy winning the 1st position at the micromouse contest held today at anna university chennai.

Invobot launches New Web Directory

Yeah i’ve been kind of busy these days with lots of work. I am sorry not to have come up with any electronics stuff for the past few days. Well while i’m exploring the USB interface and other stuff to make my own usb based PIC programmer , i just spent yesterday and today drawing up a website at http://discover.invobot.com .

This is just an effort to link up cool technical sites together using a automated system. Instead of me finding good pages and linking up on my site each and everday i thought it would be worth an effort to make an automated system to just do that. The interface has been kept simple and made as appealing as possible. I just put up a few adsense boards to cover up the page. Well making money through adsense? well not. i am expecting the directory to accumulate the best links availabale for technical guys like us. Once things add up well over there i am planning to give the desinging to a professional and get the links perfect. Next time you need not search in google for relevant technical links. just drive in to http://discover.invobot.com and find what you want.

Your Valuable contribtuion would be if you can help add up to the pages whenever you found a good page under appropriate category.

Thankyou.

cheers

SPOT UR PLACE!!! Anywhere in the world!!

Just came across a classic website, that made me roam around the world thru satelite.Yeah.. i got my place marked there! you can also spot ur place in your city.

my place is here

http://wikimapia.org/#y=13103571&x=80200136&z=18&l=0&m=a

The site consist of pictorial info on all over the world places taken from the satellite.and they are organised and managed using javascript programs – am sure this s a splendid job.The main features on this site is that u can mark ur place using the tools available in the menu at the top right.u can also search places if they are marked by somebody else before.

The other features are the zoom level, that can be adjusted for our convenience and the scale at the bottom that differs according to the places we drag on the page.All these works are done using java scripting.

Now link to www.wikimapia.org and have fun!
