- We also reserve any right to decide if your post should stay.
- Of course, it goes without saying: don't be a troll. We will ban you if you are impolite to other members in the group.
FAQ for beginners:
Q1: How do I start AI/ML/DL?
A: Step 1: Learn some Math and Programming,
Step 2: Take some beginner classes. e.g. Try out Ng's Machine Learning.
Step 3: Find some problem to play with. Kaggle has tons of such tasks.
Iterate the above 3 steps until you become bored. From time to time you can share what you learn.
Q2: What is your recommended first class for ML?
A: Ng's Coursera, the CalTech edX class, the UW Coursera class is also pretty good.
Q3: What are your recommended classes for DL?
A: Go through at least 1 or 2 ML class, then go for Hinton's, Karparthay's, Socher's, LaRochelle's and de Freitas. For deep reinforcement learning, go with Silver's and Schulmann's lectures. Also see Q4.
Q4: How do you compare different resources on machine learning/deep learning?
A: (Shameless self-promoting plug) Here is an article, "Learning Deep Learning - Top-5 Resources" written by me (Arthur) on different resources and their prerequisites. I refer to it couple of times at AIDL, and you might find it useful: http://thegrandjanitor.com/2016/08/15/learning-deep-learning-my-top-five-resource/ . Reddit's machine learning FAQ has another list of great resources as well.
Q5: How do I use machine learning technique X with language L?
A: Google is your friend. You might also see a lot of us referring you to Google from time to time. That's because your question is best to be solved by Google.
Q6: Explain concept Y. List 3 properties of concept Y.
A: Google. Also we don't do your homework. If you couldn't Google the term though, it's fair to ask questions.
Q7: What is the most recommended resources on deep learning on computer vision?
A: cs231n. 2016 is the one I will recommend. Most other resources you will find are derivative in nature or have glaring problems.
Q8: What is the prerequisites of Machine Learning/Deep Learning?
A: Mostly Linear Algebra and Calculus I-III. In Linear Algebra, you should be good at eigenvectors and matrix operation. In Calculus, you should be quite comfortable with differentiation. You might also want to have a primer on matrix differentiation before you start because it's a topic which is seldom touched in an undergraduate curriculum.
Some people will also argue Topology as important and having a Physics and Biology background could help. But they are not crucial to start.
Q9: What are the cool research papers to read in Deep Learning?
A: We think songrotek's list is pretty good: https://github.com/songrotek/Deep-Learning-Papers-Reading-Roadmap. Another classic is deeplearning.net's reading list: http://deeplearning.net/reading-list/.
Q10: What is the best/most recommended language in Deep Learning/AI?
A: Python is usually cited as a good language because it has the best support of libraries. Most ML libraries from python links with C/C++. So you get the best of both flexibility and speed.
Other also cites Java (deeplearning4j), Lua (Torch), Lisp, Golang, R. It really depends on your purpose. Practical concerns such as code integration, your familiarity with a language usually dictates your choice. R deserves special mention because it was widely used in some brother fields such as data science and it is gaining popularity.
Btw, some of us (Vincent Adultman) even suggests "English" as the language. That's because this kind of "best language" question is too frequently asked and too open-ended unless you specify what constraints you have. So don't bring up this question lightly! :)
Q11: I am bad at Math/Programming. Can I still learn A.I/D.L?
A: Mostly you can tag along, but at a certain point, if you don't understand the underlying Math, you won't be able to understand what you are doing. Same for programming, if you never implement one, or trace one yourself, you will never truly understand why an algorithm behave a certain way.
So what if you feel you are bad at Math? Don't beat yourself too much. Take Barbara Oakley's class on "Learning How to Learn", you will learn more about tough subjects such as Mathematics, Physics and Programming.
Q12: Would you explain more about AIDL's posting requirement?
A: This is a frustrating topic for many posters, albeit their good intention. I suggest you read through this blog post http://thegrandjanitor.com/2017/01/26/posting-on-aidl/ before you start any posting.

Windows 10: Activate for Free Without Using any Malicious-looking software

In the previous article, I discussed how to download Windows 10 for free and install. But after you install in that way, your Windows system limits some functionality until you activate. So, In this article I am going to show you how to active the Windows 10 after installation for free with this simple trick. Windows 10 is a personal computer operating system developed by Microsoft as part of the Windows NT family of operating systems. Officially unveiled in September 2014 following a brief demo at Build 2014, the operating system reached general availability beginning on July 29, 2015

Windows 10 Professional - W269N-WFGWX-YVC9B-4J6C9-T83GX



This is the best way to Activate windows 10 without any software.

Windows 10: Install Without Product Key; It's Free

Microsoft allows anyone to download Windows 10 for free and install it without a product key. It’ll keep working for the foreseeable future, with only a few small cosmetic restrictions. And you can even pay to upgrade to a licensed copy of Windows 10 after you install it.
Whether you want to install Windows 10 in Boot Camp, put it on an old computer that isn’t eligible for a free upgrade, or create one or more virtual machines, you don’t actually need to pay a cent.

How to Download Windows 10 and Install it Without a Key

First, you’ll need to download Windows 10. You can download it directly from Microsoft, and you don’t even need a product key to download a copy.
There’s a Windows 10 download tool that runs on Windows systems, which will help you create a USB drive to install Windows 10. If you aren’t on Windows, you can visit the Windows 10 ISO download page to download an ISO directly (say, if you’re installing Windows 10 in Boot Camp on a Mac). If you visit that page on a Windows machine, it’ll redirect you to the download tool page instead.

Just begin the installation process and install Windows 10 like you normally would. One of the first screens you’ll see will ask you to enter your product key so you can “Activate Windows.” However, you can just click the “I don’t have a product key” link at the bottom of the window and Windows will allow you to continue the installation process. You may be asked to enter a product key later in the process, too–if you are, just look for a similar small link to skip that screen.

When you select this option, you’ll be able to install either “Windows 10 Home” or “Windows 10 Pro.” Bear in mind that, if you plan to pay to upgrade to the paid version later, it’ll be cheaper to upgrade to Windows 10 Home, so you may want to install the Home version. Whatever version you choose, Windows 10 will install normally.

The Cosmetic Limitations

After you’ve installed Windows 10 without a key, it won’t actually be activated. However, an unactivated version of Windows 10 doesn’t have many restrictions. With Windows XP, Microsoft actually used Windows Genuine Advantage (WGA) to disable access to your computer. These days, Windows just complains at you in a few minor, cosmetic ways.
Initially, you won’t notice a difference. Eventually, Windows will start nagging you a tiny bit. First, you’ll notice a watermark in the bottom-right corner of your screen. You’ll also see a “Windows isn’t activated. Activate Windows now.” link at the bottom of the Settings app. This is the only form of nag you’ll see–there are no pop-up windows, for example.

Second, you’ll be unable to change your desktop wallpaper and from the Personalization > Background screen in the Settings app. You’ll see a “You need to activate Windows before you can personalize your PC” message at the top of this window, and the options for changing your wallpaper will be grayed out.

You can still change your wallpaper in other ways, however. For example, you can right-click an image in File Explorer and select “Set as desktop background.” You could also open an image in the Photos app, click the menu button, click “Set as,” and click “Set as background.” Windows 7 eventually switched you back to a black background, but Windows 10 doesn’t seem to do this.
You’ll find Windows 10’s included wallpapers under the C:\Windows\Web folder in File Explorer.

Aside from these basic limitations, your Windows 10 system will continue to work forever. There are no nag prompts aside from the watermark, you’ll get all the system updates, and everything else is completely functional. The only thing that could change this is a Windows 10 update, but Microsoft has become increasingly lenient since Windows 7.

How to Upgrade Windows 10 to an Activated Version

With Windows 10, you can now pay to upgrade a “non-genuine” copy of Windows to a licensed one. Open the Settings app and head to Update & Security > Activation. You’ll see a “Go to Store” button that will take you to the Windows Store if Windows isn’t licensed.

In the Store, you can purchase an official Windows license that will activate your PC. The Home version of Windows 10 costs $120, while the Pro version costs $200. This is a digital purchase, and it will immediately cause your current Windows installation to become activated. You don’t need to purchase a physical license.
We installed Windows 10 Professional as an example here, so the Windows Store will only let us purchase the $200 Windows 10 Pro license.
This option may not be available in all countries. The prices here are for the US version of the
 Windows Store. Microsoft charges different prices in different countries and currencies.

---

Windows 7, 8, and 8.1 worked about the same way. Microsoft just didn’t officially allow you to download Windows without a product key, and there was no way to fully upgrade to a licensed system from within Windows. That makes this all the more tempting with Windows 10–for example, you can install Windows 10 in Boot Camp on your Mac for free and, if you find yourself using it frequently, you can quickly pay to remove the watermark if that’s worth it for you. It’s like a free demo, and you can use it to make all the virtual machines you like for testing purposes.
Sure, the license agreement may say you’re not supposed to use it without a key, but Microsoft’s license agreements say all sorts of confusing things. Microsoft’s license agreement still forbids using the popular “OEM” copies of Windows 10 on PCs you build yourself. If Microsoft doesn’t want people using unactivated copies of Windows 10 for extended periods of time, it can release a system update that disables this.

Creating Apple ID without a Credit Card

Having an Apple ID is a prerequisite to do just about anything related to Apple services. If you want to buy music on iTunes, download apps in the App Store, or use iCloud, you must have an Apple ID.

A few years ago, linking a credit card to an Apple account was mandatory. But Apple has changed its stance and has been letting users create an Apple ID without a credit card for a while now.

Whatever your reason might be to do so, we are going to show you how to create an Apple ID without a credit card…

Note that if you don’t link a credit card or other payment method to your Apple ID, you will obviously not be able to complete purchases, but you will however be able to download free content, such as free apps.

Creating an Apple ID without credit card or other payment method

The following steps were performed on an iPhone, but the process is the same whether you use an iPod touch, an iPad, or even iTunes from your desktop computer.

1) Make sure you are not signed in any Apple account. If you are, simply sign out.

2) Go to the App Store and look for any free application. The application doesn’t matter so just grab the first one you see.

3) Tap the “Free” button once. It will turn into an “Install” button. Tap it again to initiate the download. At this point, the App Store app will ask you to either sign into your account or create a new one. Select “Create New Apple ID.”

4) Select your country or region, then tap Next.

5) Tap “Agree” twice to agree to the terms and conditions. Alternatively, if you have 7 hours to spare, you may first go through the terms and conditions, then agree to them.

6) Enter the required information to create your new account. This includes email address, password, date of birth, and a few security questions. Tap “Next” when you’re done. Make sure you use an email address that is not currently registered or was not previously used as an Apple ID. If necessary, create a new email address.

7) Under Billing Information, make sure to choose “None.” Then enter your billing address.

8) Apple will send you a confirmation email to the email address you provided. Check your emails and click the “Verify” link in the email Apple sent you, then log in using your newly created username (your email address) and password.

9) Finally, go back to the App Store application, and sign in your new account.

You should now be able to download free content from Apple. If you ever try to download paid content though, Apple will ask you to update your payment information and provide a credit card.

Report: Apple's new iPhone 6 could have biggest initial production

Apple is ordering a combined 70 to 80 million units of two big-screen versions of its next iPhone, its largest initial production to date, according to a report in The Wall Street Journal.

The company is anticipating large demand for the so-called iPhone 6 as it will be available with screens measuring 4.7 and 5.5 inches diagonally, the report said, citing unnamed sources.

The 70 to 80 million units by Dec. 30 would be much more than the 50 to 60 million units last year for the iPhone 5S and 5C, which have 4-inch screens. The iPhone 4S has a 3.5-inch display.

Apple has asked component makers to get ready to turn out up to 120 million new iPhones by the end of the year to take into account a possible higher failure rate for displays, the report said.

Manufacturing the 5.5-inch screen could be tricky because of the complexity of integrating touch sensors into the LCD, it said, adding that using sapphire crystal instead of glass for the display would add to the difficulty.

The new screen size has been the subject of much speculation as displays have taken up more phone real estate in recent years.

Until 2011, 4 inches was the largest screen for most phones on the market, but it has become the minimum since 2013.

Apple rival Samsung posted an ad on YouTube on Monday that depicts an iPhone user with “screen envy” while ogling the Galaxy S5, which has a 5.1-inch screen.

Apple did not immediately respond to a request for comment on the report.

Taiwan's Quanta to start mass production of Apple's smartwatch in July - source

A woman looks at the screen of her mobile phone in front of an Apple logo outside its store in downtown Shanghai September 10, 2013.

(Reuters) - Taiwan's Quanta Computer Inc will start mass production of Apple Inc's first smartwatch in July, a source familiar with the matter said, as the U.S. tech giant tries to prove it can still innovate against rival Samsung Electronics Co Ltd.

The still-unnamed watch, which Apple followers have dubbed the iWatch, will be the company's first foray into a niche product category that many remain skeptical about, especially as to whether it can drive profits as growth slows in tech gadgets.

The production will be a boost to Quanta, whose work for Apple so far has focused on laptops and iPods, product lines that are in decline. Quanta's role, though, is likely to raise questions about what involvement Hon Hai Precision Industry Co, one of Apple's biggest suppliers, will play in production.

While the watch has been widely expected, the start date of its mass production and the extent of Quanta's involvement were not known until now. Mass production will start in July and the commercial launch will come as early as October, according to the source and another person familiar with the matter. The sources requested anonymity because Apple's production plans are private.

Apple will introduce a smartwatch with a display that likely measures 2.5 inches diagonally and is slightly rectangular, one of the sources said. The source added that the watch face will protrude slightly from the band, creating an arched shape, and will feature a touch interface and wireless charging capabilities.

The source said Apple expects to ship 50 million units within the first year of the product's release, although these types of initial estimates can be subject to change. The watch is in trial production at Quanta, which will be the main manufacturer, accounting for at least 70 percent of final assembly, the source said.

Like many other smartwatches, Apple's watch will be able to perform some functions independently, but tasks like messaging and voice chat will require connection to a smartphone, according to the source. The device will only be compatible with gadgets running Apple's iOS, like its flagship iPhone, one of the sources said. Most mainstream smartwatches collect data about the user's heart rate and other health-related metrics, in addition to facilitating tasks like checking e-mail and making phone calls.

A third source said LG Display Co Ltd is the exclusive supplier of the screen for the gadget's initial batch of production. It also contains a sensor that monitors the user's pulse. Singapore-based imaging and sensor maker Heptagon is on the supplier list for the feature, two other sources said.

Apple declined to comment. Quanta, LG Display and Heptagon also declined to comment.

GAME-CHANGER? Apple's smartwatch will follow similar devices by Samsung, Sony Corp, Motorola and LG Electronics Inc - gadgets that tech watchers say have not been appealing or user-friendly enough to ignite a wave of mass adoption. But the market is growing fast, with data firm IDC saying that worldwide shipments of wearable computing devices, including smartwatches, will triple this year over 2013. Apple has already dropped hints of its plans in this arena, hiring the former chief executive of French fashion house Yves Saint Laurent, a unit of Kering SA, and proclaiming that it will introduce "new product categories" this year. Many are hoping that Apple's entry into the field of so-called smart wearables will transform the industry like the company's iPhone did in 2007. Some forecast that smartphone sales, the current cash cow of the consumer tech world, will lose momentum as the market reaches saturation. IDC predicts that worldwide smartphone sales will increase 23 percent this year, slower than the 39 percent last year, and that annual growth will average only 12 percent from 2013 to 2018.
