went for a RMS's session

Last friday i went for Richard Stallment session who is launched the GNU project.Actually it was very interesting session.And he emphsised the what should be the purpose of the free software and he furter said we should dicatate linux as GNU-slash Linux.Becuase linux main part is the GNU.

Nature-inspired visualization

Visualizations of complex interrelationships have the potential to be complex and require a lot of cognitive input. When creating new approaches for visualization we can derive analogues from natural systems. People interact with the nature very closely Hence natural inspired concepts can be used to cognitive amplification , moving the load from the user's cognitive to their perceptual systems and thus allowing them to focus their cognitive resources where they are most appropriate There are two systems as follows:

  1. physical-based model
  2. biological inspiration

Lot of day today actions are happening mediated by technology. So these action can be recorded and analyzed .At that point we will be able to find some interesting patterns and interesting thing about the data. These result can be used for yielding insights into our behavior, desires and goals, providing marketing companies with identified opportunities to sell new products into, or medical companies with information on appropriate healthcare, or governments with information on their citizens and enemies, the spread of disease, the social networks of texting and blogging.We want to find the effective methods to represent those findings.

In 1973, Herman Chernoff introduced a visualization technique to illustrate trends in multidimensional data. Normally we change our expression time to time. But we can easily identify them if there is slightly different. This concept is the base for Chernoff faces technique. Different data dimensions were mapped to different facial features, for example the face width, the level of the ears, the radius of the ears, the length or curvature of the mouth, the length of the nose, etc. Chernoff faces are just a cartoon like faces. With this faces we can display complex multivariate data. They draw upon the human mind's natural ability to recognize small differences in facial characteristics and to understand many facial characteristics at once. Several Variables can be assigned to facial characteristic and according the condition expressions can be generated.

As an example, here are some team statistics from the 2005 baseball season represented in a table and then as a series of Chernoff Faces:(Go)

Working with Agent Technology

Currently i am doing my 4th year project based on Agent Technology.It is really cool and also new experinece.Basically the output will be the intelligent agent who is living in your operting sysem and you can command to him wtih Natural Language.
In here we are using JADE flatform and Protege to develp the the system.

Akeelah and the Bee

A heart-warming, triumph-over adversity drama, AKEELA AND THE BEE centers on a precocious eleven-years-old girl, Akeelah Anderson, form south Los Angels, who is discovered to have a talent for words. In spite of the objections of her mother Wanda,Keke enters a spelling contest. Her gift takes her to compete in the National Spelling Bee, the most famous competition of its kind in the world….

One of fabulous phrase attached with this film

“Pulchritude-its derive form Latin word pulcher meaning Beautiful .Isn’t it?

You know that feeling where everything feels right? Where you don't have to worry about tomorrow or yesterday, where you feel safe and know you're doing the best you can? There's a word for that, it's called love.

Information visulization

Information visualizaion can be states as follows:

The use of computer-supported, interactive, visual representations of abstract data to amplify cognition.

I feel if Ptolemy did not find a way to represent a location still we don't know where we are in this world. This is a simple example which shows, to amplify our cognition there should be a stimuli.

Then information visualization is highly efficient way for the mind to directly perceive data and discover knowledge and insight from it. So lots of researches are going on this area. The reasons for that is

  • Human beings are tremendously influenced by sensory perceptions
  • The way that we learn, grow, understand, and adapt is based on our ability to view, perceive, and conceptualize thoughts and ideas
  • The power to visualize and graphically represent results, ideas, solutions, and problems in multiple dimensions, as well as to manipulate data and virtually collaborate with others, is the next big revolution in technology.
  • This will help to user to reach a decision without much effort.

These reasons may be the root course to born following Chinese proverb

Tell me and I’ll forget…

Show me and I may remember…

Involve me and I’ll understand.”

That is why information visualization plays major role in following areas.

Medical Science,Financial Sector,Data mining,Software visualization,Geographic visualization,Forecasting,Morphological analysis,Cave Automatic Virtual Environment.

There are lot of dimensional types exist in information visualization

• Temporal
One-dimensional (1D)
Two-dimensional (2D)
Three-dimensional (3D)
Multi-dimensional (MultiD)

More detail of about this dimension are available at On-line Library of information visualization Environment at

Start to blogging.....

I created this blog bit earlier.But i didn't use it until today.With the dawn of 2008 hope to continue blogging.Its just like beginning to use a house which was not used for a long time . So hope to enjoy by blogging the things.
