Introduction to machine learning with Python:

Machine learning science is a type of artificial intelligence science (AI) that allows automated media to learn without clear programming. It focuses machine learning on the development and programming of computer software and can therefore change when there is a change of data in the sense of new data. In this article, we will look at the basics of machine learning and the implementation of a simple machine learning algorithm using python. 

Setting up the environment: 

 Python programmers are still developing a lot of tools to support programmers in implementing robotics. Among these tools and units are numpy, scipy and scikit-learn. 

You can install it on Python using the cmd order: pip install numpy scipy scikit-learn; 

 A better option would be to download the miniconda or anaconda packages for python, which are pre-supplied with these packages. 

Follow the instructions here to use anaconda. Introduction to machine learning: Machine learning involves a computer being trained using a given data set and using that training to predict the properties of a given new data set. 

For example, we can form a computer by providing it with 1000 images of cats and 1000 other images that are not of a cat, and tell the computer each time whether an image is a cat or not. Then, if we show the computer a new image, then from the above training, the computer should be able to tell whether that new image is a chat or not. 

 Each type of learning can rely on different algorithms: 

supervised learning 

Classification 

Regression 

Unsupervised learning 

There are many specialized algorithms in the field of forecasting process and training for data analysis. We transmit the training data to an algorithm, and the algorithm uses that training data to give predictions on new test data. One such algorithm is K-Nearest-Neighborclassification (KNN classification). 

It takes test data and finds k data values closest to that data from the test data set. Then it selects the maximum frequency neighbor and gives its properties as a prediction result. Implementation of the KNN classification algorithm using Python on the IRIS dataset.

learning programming with the Python language:

Here is a python script that illustrates the knn classification algorithm. Here we use the famous iris flower data set to form the computer, then we give a new value to the computer to make predictions about it. It contains more than 50 samples of each of Iris's three types (Iris setosa, Iris virginica and Iris versicolor). Four characteristics are measured from each sample: The length and width of the seal as well as the petals are represented by some centimeters. We train our program using this data set, and then use this training to predict the species of an iris flower with given measurements. Note that this program may not run on the Geeksforgeeks IDE, but it can run easily on your local python interpreter, provided you have installed the required libraries.

learning programming with the Python language:

As you learn programming with the Python language, you will see the increasing number of techniques for analyzing and using data. Machine Learning is probably one of the areas you want to master (since you are on this page). Machine Learning allows you to make predictions by introducing data into complex algorithms. The uses of Machine Learning are endless, making it a major skill to add to your CV. In this cours , I explain the basic principles of Machine Learning and how to get familiar with Machine Learning with Python. Fortunately for us, Python has an incredible ecosystem of libraries that facilitate the application of Machine Learning. We will use the excellent Scikit-learn, Pandas and Matplotlib libraries in this tutorial.
