The Netflix Challenge – A $1 Million-Worth Crowdsourcing Project

A FORMIDABLE CHALLENGE October 2006, Netflix launched a formidable challenge: whoever would come up with a software that was 10% better than Cinematch, the Netflix software for predicting the movies customers would like, would earn a $1 million prize!

Tens of thousands of people from all over the world started working on this task right away, and each day teams submitted their updated solutions to the Netflix Prize Web page. Netflix instantly calculated how much better than Cinematch they were. Even if there were so many people working on the challenge, it took almost three years before a team came up with results that surpassed the 10% barriers. The winner was BellKor’s Pragmatic Chaos, a seven-person team of statisticians, machine-learning experts and computer engineers from the United States, Austria, Canada and Israel.

THE IMPORTANCE OF THE RESULTS The Netflix Cyberflix tv apk contest was largely followed not just because of the $1 million prize, but because of its lessons which could extend well beyond improving movie recommendations. The data base made available by Netflix for this competition -over 100 million ratings that more than 480,000 users gave to nearly 18,000 movies- was one of the largest real-life data sets available for research. The outcome of this project is most valuable, as a large-scale predictive model can be applied across the fields of science, commerce and politics.

APPLICATIONS: CROWDSOURCING -A MODEL WITH GREAT POTENTIAL The Netflix contest is another project that proves how effective crowdsourcing can be. Before launching this challenge that was open to everyone out there in the crowd, Netflix’s founders had tried for years to improve their software, with only incremental results. So, in this case, the most efficient way of solving the task was neither hiring a highly qualified professional to do the job, nor outsourcing the task (employ a third party to solve the task), but crowdsourcing it.

The progression of the results that were achieved and the way teams came together, especially in the last part of the contest, suggest that this kind of Internet-enabled approach, known as crowdsourcing, can be applied to complex business and scientific challenges.

The blending of different statistical and machine-learning techniques “only works well if you combine models that approach the problem differently,” said Chris Volinsky, a scientist at AT&T Research and a leader of the Bellkor team. “That’s why collaboration has been so effective, because different people approach problems differently.”

Another detail that is very relevant to the power of crowdsourcing is that among the top teams there were not only academic researchers, but also laymen with no prior exposure to collaborative filtering, who were virtually learning the problem space from scratch.

CROWDSOURCING BENEFITS So, we can see that the benefits of crowdsourcing that I enlisted in my previous post apply in this case too. I said there that one benefit of crowdsourcing for the organization is that it can tap a wide range of talent that might not be present in its own organization. And, on the consumer’s side, the benefit is that crowdsourcing opens the door for virtual unknowns in their fields to gain large-scale recognition for their talents. And that is exactly what happened in this case too.

The Cost of CBD Parking Space – Renting Parking Space May Be a Better Option

As with any major city, the cost of parking in the Sydney CBD can be out of control, particularly for the consumer who doesn’t know where exactly to look for the best bargains. CBD parking is also a haven for parking fines during the weekdays and business hours for those who don’t know any better. There are certainly parking stations that are available for these situations but those can be subject to large costs as well. The central business district is important, as it contains many of Sydney’s largest companies, and many of the city’s most important business centres. As a result, it is imperative for any business person to find reasonable parking in this district during business hours.

Determining the cost of CBD parking in Sydney can be quite confusing for the unprepared. Parking stations will appear full and can all have a varying rate of day parking. How is a newcomer or even a regular to Sydney’s CDB supposed to navigate this crazy world of parking? cbd fruchtgummis All that is needed is to ask around and maybe look for a company that specializes in navigating or finding an alternative to this crazy world of parking space.

The situation becomes even more ridiculous during major Sydney events etc. During this time, CBD parking in Sydney can become basically impossible, with the influx of visitors from all over the state, country or even the world. Sporting events, music festivals and religious events will ensure that the normal parking spots are filled when these events occur. For those looking for their usual parking during these events, they may be out of luck.

Fortunately, there are solutions. There is a multitude of private owners of parking space out there who are willing to sell or rent parking space. In this way, CBD parking in Sydney does not have to be the nightmare that it as for most people. Renting private CBD parking in Sydney can be the most cost-effective solution to this increasing problem.

What You Need To Know About Timber Staircase Design

Since centuries, timber is accepted as universal material for stairs. However, the concept we have today has been totally remodeled. Unlike early days, you can see different materials used in staircase design, like glass, steel, aluminium, stones tiles, etc. But the charm that lies in timber cannot be matched by any other material. While, timber offers unparallel beauty, it can be an odd piece in the house if not chosen appropriately. Here are few things about timber step that you should know before you make your choice for design:

Different timber different jobs

Timber species greatly differ in their characteristics. One wood type that is suitable for kitchen furniture may not be appropriate for living room furniture. Say, Brush Box is suitable for treads and risers, but is inappropriate for strings, balusters and newels. staircases UK Timber types may not cost you too high if you go for quality, unless you opt for something exclusively exotic. If possible you can check out the wood samples at staircase design stores that are commercially used for this purpose.

Match the timber type

Before making your choice why not look at the type of wood used in your furniture? You can harmonize or match rest of the wooden item with stairs in terms of their pattern and design. They naturally differ in grain patterns and color that are easier to match by carpenters.

Learn parts and terms of stairs

By learning parts and terms you will be able to describe your requirements and will also help you understand about what you are ordering. Often people don’t order to make entire stair but ask for parts. Unless you know about the related terms how will you explain salesman what do you want? Also without knowledge you will be unable to negotiate the quotation marked by different vendors.

Finishing your staircase design

Wooden creations cannot mark their presence until they are polished. Usually, finishing of any wood is done in many different ways, such as French polishing, staining, painting and carpeting. However, not all finishing methods are meant for all timbers, which can significantly affect your choice of wood. It is important to finish the newly installed wood as unfinished woods are more likely to scratch. Therefore, avoid walking on the wooden steps until they are polished. Also, don’t forget to seal them within a week of its completion.
