Netflix drops $1 million algorithm, goes all-in on streaming recommendations

 

Netflix awarded a $1 million prize to a developer team in 2009 for an algorithm that increased the accuracy of the company’s recommendation engine by 10 percent 다운로드. But today it doesn’t use the million-dollar code, and has no plans to implement it in the future, Netflix announced on its blog Friday 윈도우7 영문 언어팩 다운로드.

The post goes on to explain why: a combination of too much engineering effort for the results, and a shift from movie recommendations to the “next level” of personalization caused by the transition of the business from mailed DVDs to video streaming 다운로드.

Netflix notes that it does still use two algorithms from the team that won the first Progress Prize for an 8.43 percent improvement.

It turns out that all the prize-winning work was perfect for DVD-by-mail where users add something to their queue and, best-case scenario, receive it the following day 센스 톡 무료 다운로드. But, now that instant streaming is taking over the parameters have changed. Viewers want something to watch immediately and like the option of flipping between several options 쓰리필 다운로드.

That is why the Netflix updated all of its interfaces to show rows of movies giving you many, many options. It’s a subtle shift from finding the one movie you will love two days from now, to showing all the possible movies you might want to watch right now 다운로드.

I guess that is the simplest way to put it, but if you want to know more the Netflix personalization science and engineering team, Xavier Amatriain and Justin Basilico, posted a lengthy and detailed, but interesting write-up, Beyond the 5 stars 한게임 신 맞고 다운로드.

Google challenges any hacker to take down Chrome – “I am the king of the world!”

Google Will Offer $1 Million In Rewards For Hacking Chrome

For the last three years, Google’s Chrome browser has left the world’s premiere hacking competition unscathed, even as Firefox, Internet Explorer and Safari have all been taken down 다운로드.

Google announced Monday evening that it’s offering up to a million dollars in rewards at the annual Pwn2Own hacking contest, which takes place next week at the CanSecWest security conference in Vancouver 산돌체 폰트 다운로드. Hackers don’t necessarily need to target Chrome to win a chunk of that money: Google is paying $20,000 to any participant who can exploit hackable bugs in Windows, Flash, or a device driver, security problems that would affect users of all browsers 영화 취화선 다운로드. But for hacks that include flaws specific to Chrome, Google will pay $40,000 each, and for those that exploit only bugs in Chrome, the company will shell out $60,000, up to its million dollar limit 닥터 린타로 다운로드.

Since Chrome first appeared as a target in the Pwn2Own contest in 2009, participating hackers haven’t even tried to exploit the browser…that’s a sign that none of the researchers could find a chink in Chrome’s armor 다운로드.

Even when Google offered an extra $20,000 to anyone who could hack its browsers last year, no one took up the challenge.

Who’s having a fantastic struggle? Show me your struggle. That is something that should be rewarded. (changing praise in schools)

For decades, the prevailing wisdom in education was that high self-esteem would lead to high achievement 다운로드. The theory led to an avalanche of daily affirmations, awards ceremonies and attendance certificates — but few, if any, academic gains.

Now, an increasing number of teachers are weaning themselves from what some call empty praise 카드워즈 다운로드. Drawing on psychology and brain research, these educators aim to articulate a more precise, and scientific, vocabulary for praise that will push children to work through mistakes and take on more challenging assignments 윈도우 8.1 순정 iso파일 다운로드. Consider teacher Shar Hellie’s new approach in Montgomery County.

To get students through the shaky first steps of Spanish grammar, Hellie spent many years trying to boost their confidence 다운로드. If someone couldn’t answer a question easily, she would coach him, whisper the first few words, then follow up with a booming “¡Muy bien!”
