A Card Game for Teaching Machine Learning

  • I have developed a card game for my students to help them understand the important principles of machine learning.
  • The students discover the most important ideas in a playful way and develop a feeling for the functioning of machine learning procedures.
  • The task is to divide the cards into 4 groups, which the students think to belong together.
  • The task of the students is, therefore, to assign which of the 4 groups from task 1 belongs to which class of objects.The additional cards stand for a labeled dataset and the task clarifies the principle of supervised learning.
  • The player with the card with the highest number of vertical lines wins the round and receives all 4 cards.
  • (This can be judged by 2 of the players.) - If there are more cards of the trump category in the round, the trump card with the most lines wins.

The Irishman is very long and very popular, says Netflix

  • Netflix subscribers in more than 26 million homes around the world watched the movie in the first week it was available on the streaming service, Netflix announced today.
  • The most important caveat, though, is that we don’t really know how The Irishman’s audience compares to that of other stuff on Netflix, because Netflix doesn’t provide viewing data for most of its shows and movies, save for a handful of things they want to highlight.
  • The dual release indicates that Netflix is targeting at least three separate audiences when it announces numbers like these: Wall Street, which needs to decide whether the company’s stock is worth buying; Hollywood talent like Scorsese and De Niro, who need to decide whether they should work with Netflix over a different TV network, streaming service, or movie studio; and people like you and me, who may be more tempted to watch something if we know other people have watched it.

Shell-Backed Developer Completes Georgia Solar Farm for Facebook

  • This site is operated by a business or businesses owned by Informa PLC and all copyright resides with them.
  • Informa PLC's registered office is 5 Howick Place, London SW1P 1WG.
  • Brian Eckhouse (Bloomberg) -- A Royal Dutch Shell Plc-backed solar developer commissioned a solar project in Georgia that will help power a Facebook Inc. data center.
  • Silicon Ranch Corp.’s 102.5-megawatt plant in Early County is Facebook’s first solar project in Georgia, and was developed as part of an agreement with local utility Walton Electric Membership Corp.
  • Walton Electric recently signed a deal with Silicon Ranch for another solar project in the state that will power the Facebook data center.
  • The 107-megawatt facility in Denton is expected to be commissioned in 2021.
  • Facebook has signed almost 950 megawatts of clean power-supply agreements this year, the third-most globally among corporations, according to BloombergNEF.

Google’s quantum supremacy algorithm has found its first practical use

  • Google is putting its supreme algorithm to work.
  • In October, the company announced that they had reached quantum supremacy – the point at which a quantum computer can complete a task that no classical computer could practically achieve – with an algorithm that could verify that a given set of numbers was randomly distributed.
  • Now, that algorithm is finding its first practical use as a random number generator.

How to turn off call forwarding on an iPhone, or turn it on to receive calls on a different phone

  • Your iPhone includes a simple call forwarding feature that lets you redirect all incoming calls to a different number.
  • When you set up call forwarding, your iPhone won't ring and all of its calls will go to another phone.
  • If you set up call forwarding temporarily, it's easy to turn off so your iPhone gets calls again.
  • Here's how to turn the feature on or off.

Probability Theory for Physically Based Rendering

  • As with the Riemann sum, as n approaches infinity, the average of the samples converges to the expected value, and thus the true value of the integral.
  • It may sound obvious, but what we need for Monte Carlo integration are uniformly distributed random numbers, i.e. every value must have an equal probability of being generated.
  • Figure 8b shows the effect of stratification: the domain is subdivided in eight strata, and in each stratum a random position is chosen, improving uniformity.
  • For a uniform random variable in the range 0..1, the pdf is simply 1 (Figure 10a), which means that each value has an equal probability of being chosen.
  • In many cases the function we wish to integrate is unknown, and the only way to determine where it is significant is by sampling it – which is precisely what we need the pdf for; a classic chicken and egg situation.

Quantum computer sets new record for finding prime number factors

  • Quantum computers could one day threaten the safety of the internet by breaking encryption – and now they are a step closer.
  • A quantum computing start-up company called Zapata has worked with IBM to develop a new way to factor large numbers, using it on the largest number that has been factored with a quantum computer so far.
  • The team found that 1,099,551,473,989 is equal to 1,048,589 multiplied by 1,048,601.

Mathematician Proves Result on ‘Dangerous’ Problem

  • Earlier this year one of the top mathematicians in the world dared to confront the problem — and came away with one of the most significant results on the Collatz conjecture in decades.
  • In the 1970s, mathematicians showed that almost all Collatz sequences — the list of numbers you get as you repeat the process — eventually reach a number that’s smaller than where you started — weak evidence, but evidence nonetheless, that almost all Collatz sequences incline toward 1.
  • Tao’s key insight was figuring out how to choose a sample of numbers that largely retains its original weights throughout the Collatz process.
  • For example, Tao’s starting sample is weighted to contain no multiples of 3, since the Collatz process quickly weeds out multiples of 3 anyway.

Google brings Verified SMS to curb spam in Android Messages

  • Google is now ramping up its efforts to curb such texts by introducing a Verified SMS feature in Android Messages.
  • Now when you receive a text from a strange number, Google will verify if it came from a legitimate business.
  • If so, you’ll see the business name and logo in addition to a verification badge in the message thread.
  • Of course, this doesn’t mean that texts without a badge are illegitimate; Google is just beginning to roll out the feature and not all businesses are in its database yet.
  • Still, the feature should provide some peace of mind next time you get a text asking for a verification code.
  • It’s part of Google continued efforts to reduce spam.
  • In some countries, Android Messages already alerts you if it suspects a message is spam – now that feature is rolling out broadly in the US.

Apple’s new parental controls on iOS can be bypassed

  • Due to some bugs related to iCloud’s contact sync feature, it turns out the new privacy controls can be bypassed without much effort, which could let kids call and text people (or total strangers) they might not be allowed to communicate with, as found by CNBC.
  • Apple confirmed to CNBC that it’s working on fixes, but it’s not a good look for a company that prides itself on security and privacy, and especially when the bugs are in a feature designed in part to protect kids.
  • It seems there are a couple ways to bypass the Communication Limits — though they apparently only work if the phone’s contacts aren’t stored on iCloud.
  • CNBC also said that kids can get around Communication Limits restrictions by using Siri on an Apple Watch.
