Hahahahaha.

You are sure of it, right?

Yes, very good. Youve done very well, so lets keep it up for a little while.

Continuing from KO Telecoms K-recommendation system, if he could obtain Shinseki groups PS System contract, then Kim ManHos position in Mirae IT would shoot up so that nobody would be able to touch him easily.

Team leader?

Son SeokHo?

Its a person team leader Jeong DanBi scouted when making the team. He graduated from correspondence college and worked as a freelancer before going to Shinseki. He has experience in working in IT labor union.

This It seems like he has quite the ability since he could identify the problem with our system.

100 million (85000 USD) along with a team leader-level position.

How much do we have from gathering from our cooperative companies?

Say its a deal. But, make sure to add in the condition of when the work is completely finished.

Along with interfering with the opponent, he had to prepare his work flawlessly. That was one of the driving power behind Kim ManHos rise from an ordinary employee to a director.

Yes. An ByungHoon is an open source contributor. And it seems that its a source related to recommendation too.

Yes.

He couldnt stop smiling even until the end of the conversation.

YongHo organized his finding on the bug window on a notepad.

Cases where the bug window recognizes something as an error.

Problems with performance.

Problems with logic (A precondition is needed)

Normal errors.

Applying the rules of the bug window, there was no output stated in the document.

YongHo added the wanted value to the document.

And clicked the shortcut key to run the java program.

Title : Tuning of the collaborative filtering (a theory that is used a lot in recommendation algorithms) of the maut system

Result : Various algorithms, includingclassificationandsingular value decompositionshould be used in combination.

The details are as follows.

The bug window alarm didnt end with just tens of lines. It was filled with words YongHo saw for the first time and it was going over 2 digits like it was nothing.

YongHos eyes started shining more than ever.

And all he needed to do now was to follow what it says. YongHos hands started moving faster than his eyes.

Seattle, America.

Team name : The Dessert.

Dave, how is it?

Dave, with curly blond hair, spoke while smiling as if it was obvious.

Through consistent algorithm tuning, he was renewing the record every day.

Raising it by 0.2% isnt easy as it seems.

Youre right. Last year, they only got this far through collaborating.

Combining algorithms that other high-level teams used by sharing algorithms that they used this method was used to achieve a 9.5% increase in performance.

The winning team with 10% increase in performance will receive twice the amount of 1 million dollars 2 million dollars, called the Grand Prize.

It seemed like it would be achieved but couldnt so it stirred the hearts of many challenge-seeking people.

The sparkling night scenery of Seattle which would captivate any gaze.

It was a sleepless night of Seattle.

Even Seoul wouldnt lose out to any city in the world comparing night scenery.

Its done.

RMSE Score : 0.8669 (+10.0%)

I, is that true?

His skin was all rough due to not sleeping but his eyes were shining brightly. It wasnt the eyes of a liar.

RMSE Score : 0.8669 (+10.0%)

N, no way.

How, How did you do it?

Delight.

This is the way i did it, first I

The shocked mouth never closed.

However, it wasnt.

He wasnt a source stone that one needed to refine, but he already was exuding his value.

Team name: Shinseki Maut.

It was the name of the team which was newly added to the Leaderboard of the NetFlax Prize.

Growth of distribution companies were slowing down.

In contrast, the sales in online shopping was increasing explosively.

Distribution service-based companies like Shinseki had to follow the trend. Thats why the PS(Preference Shoot) System was suggested.

A interim report-like demonstration day, which should shoot the chairmans preferences, instead of the customers, began.

It was decided that they would select the system with more sales by letting the system being developed by Jeong DanBis team and the system being developed by Mirae IT compete with each other.

Paper competition.

An ByungHoon, who works as an open source contributor for open source maut.

These two things were the strengths that Mirae IT was emphasizing.

Jeong DanBi stepped up.

In the middle of the big screen was just one number.

We cant survive now by striving to be first. We need to start off as first.

Team name : Shinseki Maut.

Chairman Jeong JinYong, who was watching from the middle, changed his expression.

Did Mirae IT say that they had an open source contributor for open source maut? Then we have a committer. There may be people who already know this, but to become a contributor, one needs an approval from a committer. Meaning that head researcher Son SeokHo approved manager An ByungHoon to participate in this project.

The era of fast follower is gone. Now, we need to become the first mover. Our PS System will pave the way.

Just that some people couldnt acknowledge it.

After the presentation ended, An ByungHoon offered his hand to YongHo in gladness after finding him.

Oh, manager.

You How much did you work in order to become like this?

The current YongHo was exactly like that.

An ByungHoon threw a line with a worried face.

YongHos face had gone bad.

In compensation for the position of 1st, he had to pay with his health.

H, head researcher.

Today, for once, he wasnt eating sweet bean bread.

An ByungHoon was flustered at those words.

Nice to meet you. Im called Son SeokHo. Meeting offline like this is a first. Sircoffee.ahan.

Coffee.ahanwas the nickname An ByungHoon used while acting as an open source contributor.

It was the meeting of the committer and contributor for the open source maut project.
