When we still sat on the High School desk, we were often crammed by a number of new vocabularies. We must memorize tenth of vocabs until night, we feel so sleepy but tomorrow we have English test. But now we have already known much of those vocabs very well. Even though we forget a word and we hear someone say that word, we will think, “Wait, look like I've heard this word before”. Our brain will search the word, match the word with our “database”. Just like my lecturer said, “Human brain is amazing.”

Yeah, I really agree with my lecturer statement. How can we be considered as smart? I ever read that it's not depend on how much data we know, but it is depend on how can we link every data that we have. For example I'll tell you about one word: mountain. If me, I'll think: mountain...hmmm, the mountain I do want to visit is Mount Fuji. Mount Fuji is located in Japan. Japan has so many anime. But watch too much anime is not good because it can make us addicted......Stop here! Mountain and addicted....it has already gone too far!

What if we apply such intelligence into machine?

In the future, we will need smart machine. A machine that's not just run the program sequentially. Do you ever write a program to process factorial number? Or the program that's used to encode and decode message? Those are sequential program, because the program processes data input by a process that has many formulas that are defined before, and then results output. Data input must be complete in order to run the program successfully.


Flowchart of sequential program

Learning machine doesn't need complete data to run, because learning machine has rules. Rules is used to handle and link incomplete data input. Unlike sequential program that must have exact input and output, learning program can handle uncertainty situation. If needed, program can add new rule from its own predefined rules, by the formula that is given before. More often the program used, more rules the program will have and hence the output will be more accurate. Just like human, more experience that we have, we will be wiser.

At the moment, learning machine is usually used in expert system, a system that act as an expert. For example a software that is aimed to ask for patient's disease. At the beginning operation, the software needs human expert involvement to enter enough rules and data that is needed. As time goes by, the software itself can link data according to the rules that the software has without human expert involvement. More rules that the software has, the result is also more satisfied and accurate.

In my opinion, a machine that can learn must be developed further, not just to investigate a problem. We can widen the need of learning machine to other aspects. For example, a robot. In first use, the robot needs human expert to control robot behavior: what robot must do when meet a kind of obstacle, what robot must do when meet another kind of obstacle. As time goes by, no matter where the robot is placed, robot knows what to do according to its experiences before (read as: according to the predefined rules). Moreover, the robot can make its own rules according to predefined rules that the robot has before, make the robot smarter and smarter.

Learning machine isn't as terrible as we see in the Terminator movie. Instead, it will help us very much.

One day, there is caterpillar lives in a garden. The caterpillar has haired skin that make it looks disgusting. Everyday the caterpillar just eat, eat, and sleep. Many sheets of leaves have been torn, withered, and fall because caterpillar eats them. But the caterpillar is never satisfied. For the caterpillar, the most important thing is she can eat and eat, until her body becomes fatty.

As time goes by, the caterpillar is bored with her everyday life. Moreover, the caterpillar doesn't have friend because other animals in the garden feel disgusted with her. The caterpillar feels sad. Then she makes a decision, she won't eat for several weeks and enclose herself into pupa until she becomes a different animal.

The caterpillar then alienates herself from the outside. She encloses herself into a pupa. Long waiting moment begins. Day by day, the hair that covered her body fall and in change, a small wing grows. The caterpillar feels hungry and bored, but strong will makes the caterpillar patient and strong in such moment.

Then the moment the caterpillar must exit from her pupa begins. Her wings are very beautiful, but she isn't yet ready to fly. There is the last process she must pass: strengthen her wings in order to fly. To do so, she must struggle to exit from her pupa with all of her strength.

For several hours, the caterpillar struggles to exit, tries to rip the pupa. Many times she fails, but she tries and tries again. She feels so tired, but she still tries. Then finally the pupa has enough torn for her to exit and fly.

All garden creature, see! A caterpillar that can fly, flap her wings beautifully! All creatures in the garden doesn't realize that in the past, it is just a caterpillar that just eat and sleep in her everyday life. They just know it as butterfly, a creature that has beautiful wings, colorize the garden.

Against anxiety
Against boredom
Against failure
Against fear
Against immaturity
Against limitation
Against temptation
Against uncertainty
I will fly, to the unheard future

No matter what dark my past is
I will leave it behind
I will deal with it, without regret
So I don't burden my future with it
So I could fly without being burdened

The moment,
When imagination plays vividly inside my mind
I will save it forever
And I will use it to drive through every moment
As long as there is chance to learn, I will learn
I will redeem all my mistakes in the past
For the people who support me very much
For the people I will meet in the future
For the sake of better future!

I will fly bravely, to the unheard future
I will fly with courage, with the light wing
I will never be afraid my wing will be injured
Coz I know, no matter my wing is wounded
It will be healed and I will fly again
