Machine Learning


As artificial intelligence (AI) becomes a hot topic, it will become increasingly important to understand some of the terms associated with this technology. Machine learning is a branch of AI that helps AI tools better understand how you do your job.

Machine learning is the field behind many of the artificial intelligence programs we see in our daily lives today. This is the method AI tools use to get new information. Machine learning allows AI tools to learn new information without being explicitly taught or programmed, making all sorts of other things possible.

You can’t programmatically tell the computer everything. This explains why machine learning was invented. Teaching a computer to do math is easy, but teaching it to draw a picture or write a cover letter is an entirely different skill where you can look at examples and reassemble the parts to make a new whole. I need a set.

There are several machine learning protocols developed by programmers that can teach AI tools how to do new things. While this reduces programming time, it often leads to increased AI tool training time. AI tools learn by inputting, testing, and learning from large amounts of data about what they should do professionally. provide feedback. Artificial intelligence uses machine learning to synthesize data and results during training.

For example, if you have an AI tool that uses machine learning to select stocks, feed it historical data about specific stocks or the market as a whole and have it analyze that data to show you when the market is going down. You can request I was ready to be bullish. Then, if you get a wrong answer, correct it until you get only the correct answer.

Its AI can theoretically be used to predict upcoming bull markets, but its accuracy depends on the dataset it was provided with, the training it received, and the machine learning algorithms that helped it learn.

Machine learning gives AI tools a way to work with large amounts of data so that they can better understand what they are seeing and eventually associate patterns with the results they need to match. Again, if the AI ​​tool is designed to identify good stock selections from technical patterns, a large amount of technical data can be fed into the AI ​​tool and displayed when it is correct. Machine learning algorithms eventually detect patterns.

This works much better for discrete data than for ambiguous data that leaves room for interpretation. If we were to use an AI program trained on the New York Stock Exchange to find tomorrow’s best stocks based on certain technical indicators, the task would be much easier, since the data would be fairly discrete.

Programmers often have some understanding of what machine learning algorithms are doing, but sometimes they don’t. When the AI ​​gets the correct answer but doesn’t know what’s going on in the program, this is commonly called a “black box” or “black box problem”.

Black boxes are exactly that. It’s the missing piece of the puzzle. For a programmer, it’s as if his AI tool walks into a room with black windows and finds a solution on its own. This is not what is happening. AI tools may be smart, but they have no sense. Yet the program, by its complex nature, is doing things that are clearly unexplainable or untraceable.

It’s important to understand how the answer is obtained, not just that the program can do the job. If your machine learning algorithm contains black boxes, you cannot guarantee that you will always get correct results. You may be associating the wrong data, resulting in the correct answer most of the time for the wrong reasons.

For example, an AI tool trained to read medical images might understand that what it’s looking at has a fracture, or that data is commonly from machines that detect fractures. you may understand. Therefore, if something vaguely leg-shaped appears, the conclusion that the leg has broken might be drawn by correlating the general shape of the machine and the image, rather than identifying the actual breakage. .
