But one of the hallmarks of practical technology is that they tend to disappear in the end. We will forget the techniques that were once easy to use, and we should not let AI technology repeat the same mistakes. Any technique requires careful review, especially for AI technologies where the risk of failure is so great. Let's take a look at how AI and machine learning affect today's technology, because when AI really changes the world, it may be too late to understand these effects. There is a common psychological phenomenon: if you repeat a word for a certain number of times, the word will eventually lose all meaning and turn into a function word with a shell and no practical meaning.
For many of us, The term "artificial intelligence" has experienced this "meaningless" process a long time ago. In the current technical field, "artificial intelligence" is almost everywhere. From TV to toothbrush, all functions can't wait to be "artificial intelligence", but the meaning of the word itself is increasingly blurred. Although the term "artificial intelligence" has been undoubtedly abused, AI technology itself is more developed than ever.

It is used for health care and war, helping people make music and books, checking their resumes carefully, judging their credibility, and processing photos taken on your mobile phone. In short, whether you like it or not, artificial intelligence will make decisions that affect your life. But this may be far from the hype and touting of AI by technology companies and advertisers. Take Oran-B's Genius X toothbrush as an example. This is one of the many devices that appeared at CES this year, focusing on the so-called "AI" capability.
However, through the words in the press release, this toothbrush only provides very simple feedback, telling you whether to brush your teeth at the right time and place. The smart sensor on the toothbrush can detect the position of the toothbrush in the mouth. Calling this thing "artificial intelligence" is basically nonsense, nothing more.
But when AI technology is not hyped, it often leads to misunderstandings. News reports may exaggerate research results and casually package a vague AI story into a "terminator" level of discovery. This may lead people to be confused about the question "what is AI?
For ordinary people who are not experts, this can be a tricky topic. People often mistakenly confuse current artificial intelligence with the "artificial intelligence" they are most familiar with: the latter mostly appear to be smarter and more conscious than humans. Experts refer to this particular form of artificial intelligence as "general artificial intelligence.
So, what exactly is AI? The picture above is from top to bottom. In fact, it is more appropriate to discuss "machine learning" than to discuss AI.
If You Must Speculate Learn Rules
The word has no mystery of "AI", but it is more helpful in explaining the role of technology. What is the way machine learning works? In the past few years, I have seen dozens of explanations, and the most useful difference is that the word "machine learning" itself: machine learning is to let computers learn on their own.
But this has led to a bigger problem. Let's look at a problem first. Suppose you want to build a program that recognizes cats. You can try to use the old method to program some clear rules, such as "the cat has pointed ears" and "the cat is furry". But what if the program shows a picture of a tiger to the program? It is time-consuming and laborious to formulate all the required rules by programming, and in the process it must involve definitions of various difficult concepts, such as the definition of "spike" and "furry".
So A better way is to let the machine learn by itself. Therefore, a large number of cat photos can be provided for the machine, and the system will view the images in a way that is unique to them. At first, it was almost randomly connected to different points, but as the experiment was repeated, the system continued to learn the updated version. In the end, you can more accurately determine which photos are cats and which are not cats.
So far, what we are talking about is something that can be predicted.
If You Must Speculate Learn The Rules by Frank J. Williams
In fact, you may have seen such an explanation before, but what is important is not the interpretation itself, but the implications it implies. Let's start with your age. The general idea is that as you get older, stocks gradually become a less desirable place to keep your money.
If you're young, you have decades ahead of you to ride out any ups and downs in the market, but this isn't the case if you're retired and reliant on your investment income. Here's a quick rule of thumb that can help you establish a ballpark asset allocation. Take your age and subtract it from This is the approximate percentage of your investable money that should be in stocks this includes mutual funds and ETFs that are stock-based. The remainder should be in fixed-income investments like bonds or high-yield CDs.
You can then adjust this ratio up or down depending on your particular risk tolerance. For example, let's say that you are 40 years old.

If you're more of a risk-taker or are planning to work past a typical retirement age, you may want to shift this in favor of stocks. On the other hand, if you don't like big fluctuations in your portfolio, you might want to modify it in the other direction. And opening a brokerage account is typically a quick and painless process that you can do in a matter of minutes. You can easily fund your brokerage account via EFT transfer, by mailing a check, or by wiring money. The brokerage account opening process is generally quick and painless, but there are a few things you should consider before choosing a particular broker:.
First, determine the type of brokerage account you need. For most people who are starting out in the stock , this means choosing between a standard brokerage account or an individual retirement account IRA. The main considerations here are why you're investing in stocks and how easily you want to be able to access your money. If you want easy access to your money, are just investing for a rainy day, or want to invest more than the annual IRA limit, you'll probably want a standard brokerage account.
Both account types will allow you to buy stocks, mutual funds, and ETFs.
On the other hand, if your goal is to build up a retirement nest egg , an IRA is a great way to go. These accounts come in two varieties -- traditional or Roth. IRAs are very tax-advantaged places to buy stocks, but the downside is that it can be difficult to withdraw your money until you get older.
The majority of online stock brokers have eliminated trading commissions, so most but not all are on a level playing field as far as costs are concerned. However, there are several other big differences. For example, some brokers offer customers a variety of educational tools, access to investment research, and other features that are especially useful for newer investors. Others offer the ability to trade on foreign stock exchanges. And some have physical branch networks, which can be nice if you want face-to-face investment guidance.
There's also the user-friendliness and functionality of the broker's trading platform. I've used quite a few of them and can tell you firsthand that some are far more "clunky" than others. Many will let you try a demo version before committing any money, and if that's the case, I highly recommend it. First off, if you're looking for some great beginner-friendly investment ideas, here are five great stock ideas to help get you started.
Of course, we can't go over everything you should consider when selecting and analyzing stocks in a few paragraphs, but here are the important concepts to master before you get started.
