Learning machine learning with Python – Learning machine learning with Python

People are becoming more and more involved in technology, and in the meantime, a branch of artificial intelligence called machine learning has emerged as a new science.

Machine learning, To reduce our hassle and give all technology and software tools the power to progress on their own (meaning the advancement of learning through our data).

Machine learning science can give a software the power that the software can use to solve some problems with the experience it has, or better to say, the software with the knowledge it has.

A good example in this field is Google. You must have understood this. That Google’s powerful search engine has the ability to learn, has not it occurred to you that as soon as you try to search for something, Google immediately guesses it?

Do you think that Google does not know what you are interested in? Doesn’t Google show a list of words related to your search at the bottom of your page? In the following, it is not bad to have a look at the article about hacking Python .

 

Introduction to Python Learning Machine

Introduction to Python Learning Machine

First of all, what is the whole Python programming language? Doesn’t Google retain the most searched words? The answer to all these questions is yes, and you should know that Google search engine is extremely smart and learns from all the behaviors of its users and learns to use it through this data that Google has taken and analyzed ( Google is the second largest brand in the world, and it is only through a search engine that it has achieved this)

But our more important discussion is learning to learn machine learning with Python. Python is a very popular high-performance programming language (we will introduce this programming language comprehensively).

That is, we use Python programming language to create software or technologies that are capable of learning from our data, just like humans who learn things using the information they receive. Join us to learn machine learning with Complete the Python (introduction to the Python language, introduction to the learning machine, and finally learning to learn the learning machine with Python).

What is Python?

Here’s how to put one together for use with your Python learning machine :

  • Full introduction of Python programming language
  • Python is a versatile, high-level object-oriented language
  • It is open source and scripted. Nowadays, you can develop any kind of program with Python language. What web applications are websites?
  • Mobile applications
  • Robotics and Mac applications (operating systems for Apple computers) and Windows (operating systems for most computers in the world).

That is why it is said that Python is a universal language. If you ask the concept of object-oriented, we must say that object-oriented programming languages ​​are languages ​​with which program development will be enjoyable. In the following, it is better to know more about Python programming language and say more.

Because they follow the laws of our world. That is, in these programming languages, there are concepts such as adjective, class (categorization), object (there are thousands of objects in the world), inheritance, and so on. Another feature of the Python language is the ability to build applications by learning machine learning.

Learning machine learning with Python is an important topic, as it is one of the first choices for machine learning. Another important feature of Python programming language is that it is open source.

In the world of open source software, that is, software that usually does not belong to a specific company and anyone can take the source code of this software and with changes in that software or programming language to offer it under another name or the same name. کردن.

This feature is extremely important because it will make Python all-round (all developers in the world can help Python develop).

 

Learning machine learning with Python;  What is Python?

Important features of Python

One of the most popular features of Python is its selection by the world’s technology giants. Companies like Google, Facebook, NASA, Dropbox, Yahoo, Instagram, Reddit, Mozilla and استفاده use Python, and this shows how important this language is.

Another important feature of Python that is perhaps the most important feature is the simplicity of Python. Python is one of the best options if you want to learn a programming language for the first time. Say above).

Python has many advantages, such as that other teammates in building a project understand the written software and can easily continue their work. You can even show your code to a specialist if needed.

For correction and revision, this feature means that code readability will be very useful for you. Unlike many programming languages, Python is too simple, meaning you can sometimes do just a few lines of code in the language you want to do, and on the other hand it is very similar to human language.

Advantages of using Python

When you want to display a phrase in Python, just write (“print Hello”) The benefits of Python are innumerable. But just know that Python is widely used in machine learning.

One of the disadvantages of Python may be runtime errors, weakness in mobile applications, differences with many programming languages ​​in the world, slowing down and که that if compared to other programming languages, Python certainly has more advantages than them (all languages Programming is flawed).

“There are two categories of programming languages: the first category does not use anyone. The second category has fans who constantly complain about it.”

Automotive industry with car learning

Learning machine learning with Python allows you to work in the automotive industry as well, because today machine learning has come with the help of self-driving car technology (this technology must learn from its own data and experience to be able to control without The car driver walks the path).

Step-by-step tutorial Learning machine learning with Python

In the topic of learning machine learning with Python, we will teach you all the steps and remember that practice, perseverance and hard work are very important in programming. First, it is necessary to explain the different stages of machine learning to you (to start learning Learning machine with Python)

  1. Collecting data
  2. Categorize data
  3. data analysis
  4. Algorithm development
  5. Check the generated algorithm
  6. Use the algorithm for better conclusions

In machine learning, there are generally three types of learning that you need to know to get started.

Machine learning, unsupervised

The first way to learn machine learning is supervised learning. In this method, the data is not tagged (for example, if the data is a collection of images, we do not indicate with a label that this image is a machine).

This means that the data sets contain only the input and there will be no output commensurate with the inputs. In fact, in this method, the learning machine does not have control over the data and does not aim to establish a connection between input and output.

Unsupervised learning is a way to find patterns in the data, with unsupervised learning we will be able to find hidden structures and patterns in the data (in order to be able to learn machine learning well, you need to have different types. Know).

 

Learning machine learning with Python;  Machine learning, unsupervised

Machine learning, supervised

The second way to learn machine learning is the monitoring method. In this method, machine learning is labeled on the data and monitored.

In fact, the data are presented with the aim of finally reaching a complete and correct result. An example of supervised learning is, imagine in our emails the text inside the emails is considered as input and the output is labeled as either spam or non-spam.

Semi-supervised learning

You should also know about the third case, called semi-supervised learning, which is actually a combination of unsupervised learning and supervised learning. This method uses both classified data, that is, the same data as we said, and unclassified data (the same as unlabeled data) at the same time (to increase learning accuracy).

The next step is to strengthen math. Without high math knowledge, you will certainly have trouble learning the machine. One of the most important things you should know about linear algebra and mathematical analysis (mathematical analysis includes concepts such as limit, derivative, functions, etc.) that you can start learning linear algebra training from the home school website .

Or if your English is very good, the Khan Academy and MIT OpenCourseWare websites have very good courses in this area.

The first in the field of mathematical analysis and linear algebra and the second in the field of mathematics required for machine learning that you can count on (If you want to progress in the subject of learning machine learning with Python, please learn the items in order and do not rush)

 

Semi-supervised learning

 

Learning machine learning is by learning mathematics

The third step is to learn the syntax of the Python language. That is, you start with Python from the ground up. The syntax of a language is called commands. The following are good books for education.

But if you want to be a good footballer, you can never become a good footballer by reading books. But with repetition, practice, perseverance and reading a great book, you can definitely become a good footballer.

The same is true in programming. You can learn programming with a book. But you have to do a lot of practice and repetition to become a real Python programmer and start learning machine learning as well. Read on for a look at the Java or Python article which one is better? Also have.

The next step is to get acquainted with some of the Python libraries for working with artificial intelligence and data analysis (of course you have to learn data analysis at this stage, so only the library for data analysis in Python will be introduced).

 

One of the most important things you can do to start learning Python is learning math
