Chapter 51 (1/2)
Coder Lee YongHo – Chapter 51: One Shot Two Kill (4)
400 billion (≈350 million USD) in annual sales
However, a yearly deficit of 30 billion (≈26 million USD)
This was the poor result of the shi+nseki Mall
Even so, they couldn’t give up on the consu froh
One part of the breakthrough was the PS System
The ai’ the custoe deficits into profits
Of the 2 months of the competition, when about half of the ti her hand at Mirae IT
“3 billion (≈26 million USD)?”
“Yes This is the sales produced due to our recommendation system”
“What about them?”
“About 13 billion (≈113 million USD), sir”
“Has one month passed since then?”
Out of the 2 months of the co
“Yes, sir”
Ki man
“Yes Tell that friend that he’s doing well That ill be counting on him in the future”
“I understand”
Until now, Mirae IT was in an absolutely superior position
Dave wrapped his head with his hands, while screa a look at the Leaderboard notice
“No way!”
RMSE Score : 08655
The first place had changed again
1 shi+nseki Maut
2 The Dark Forces
The Dark Forces, with Dave at the core, had come down to 2nd place
“Jessie, is the nu real?”
“It should be, if you can’t believe it, then call the hosts or so”
“No way This… no, I don’t have the time for this”
Jessie s at Dave, who had a fierce reaction, interestingly The shter due to the smile of the person called Jessie
“How about James?”
“He had the exact same reaction, and he seemed to write e-mails to various places?”
“Good I can’t lose like this I shall gather all the teams we don’t have a union with”
The NetFlax Prize took a ‘Winner takes all’ structure
Winner takes all
2nd place had noanyway
Dave requested cooperation fro to split the prize
The office was never quiet that day due to Dave’s fuss
After the systees First, the developers would upload the source on to the SVN
Then after YongHo’s confirmation, it would be decided whether it would be applied on to the real server
YongHo, as looking at the code, scratched his head as if he didn’t understand so
‘I definitely told him once’
He had told Lee HyunGu through Son SeokHo but there was no change
The code still stank The code that other people wrote, in no way, satisfied him either
However, Lee HyunGu was different from even them
YongHo couldn’t find any ‘efforts’ anywhere in the code, and he even thought that this was intentional He was coding exactly opposite to how Son SeokHo told him to code
‘It won’t do like this’
YongHo looked for Son SeokHo again, in the intra-coer app
Adjusting the recommendation system, which showed a 10 increase in performance in the NetFlax Prize, into shi+nseki’s PS System was by no means, easy
The core was the addition of another process
“The point of the syste what star the custoive”
“Yes”
“However, we need to go another step further for the PS System”
“I think you’re talking about the recoorized by the stars they give to the series… aht?”[1]
“…I think you’re ready to go into the world now”
The greatest joy of teaching lied in watching the growth of soHo all grown up, and couldn’t hide his joy
“No, I have a lot more to learn from the head researcher”
“What would MrYongHo do to e?”
“It was already ih?”
“You’ve seen the source?”
“Of course I did It’s made by our head researcher, who is the core of the project”
It was an era where open source was everywhere
If one goes into gethub, progra about in their heads
The sources were already implemented
The paradig from implementation to combination
And a probleradation of ability
There were a lot of instances where the people only use the is decreased Son SeokHo ary of this fact so he Ho keep this fact in mind
“And you threatened me to have a month of code review if I use the source as it is…”
YongHo said with a suppressed voice His teeth clattered when he thought about the code revieith Son SeokHoIt definitely helped hi his ability and it was also partially fun, but it remained inside his memory as a difficult time
“Did I say that?”
YongHo could only grit his teeth at Son SeokHo, who pretended that such thing never happened
“…Yes, you did”
“Oh, ok Then let’s get on with the changing the systeht?”
If recommendation never affected the customers’ actions, then Son SeokHo would have never even made the maut
If they applied YongHo’s results with the 10 increase, then the difference in sales could be reversed in just one night
‘I must buy this!’
Preference shooting
The upgrade of the PS Systean
Oh My God!
Dave was sitting in his seat dumbfoundedly He pulled out his hair for some time, and held his head down for the next, and stayed still
When looked from the side, one would think ‘What kind of madman is this?’ – automatically
“Dave, get yourself together”
“Jessie! This… is just not possible It can’t be like this, right?”
“What are you saying, you madman”
She had white skin, as expected of a white person And so, the red lips were accentuated However, Jessie’s such char lips weren’t seen by Dave
“I increased it to 105! I won against myself! I broke that unsurpassable wall!”
“So what?”
