Udemy Machine Learning course lets you develop new skills step-by-step and improve your understanding in the challenging yet lucrative field of ML.

## About this course

The Udemy Machine Learning course has been designed by two professional Data Scientists so that we can share our knowledge and help you learn complex theories, algorithms, and coding libraries in a simple way.

We will walk you step-by-step into the World of Machine Learning. With every tutorial, you will develop new skills and improve your understanding of this challenging yet lucrative sub-field of Data Science. Let’s begin with the basics of this topic from Machine Learning to the use of Python and R for Machine Learning.

## About Machine Learning

Machine learning is an application of artificial intelligence (AI) that consists of various learning methods (Supervised, unsupervised, semi-supervised & Reinforcement learning). The machine learning algorithms provides systems the ability to automatically learn and improve from experience without being explicitly programmed.

The process of learning begins with observations or data, such as examples, direct experience, or instruction, to look for patterns in data and make better decisions in the future based on the examples that will be provided. The primary aim is to allow the computers to learn automatically without human intervention or assistance and adjust actions accordingly.

## Python and R for Data Science

Machine learning and data analysis are two areas where open source has become almost the de facto license for innovative new tools. Here Python and R languages come into the picture, as they are the two most popular tools open-source and free tools used by data scientists. Both Python programming and R programming share many characteristics. These languages have developed robust ecosystems of open source tools and libraries that help data scientists of any skill level more easily perform analytical work. Python, being more concerned with predictive accuracy, has developed a positive reputation in machine learning, while R, as a language, has been used by many for statistical inference, and has gained reputation and trust in data analysis.

## When to use Python?

Python programming is widely used throughout the industry and enables easy collaboration within development teams. If you need a flexible, multi-purpose programming language surrounded by a large community of developers and extendable with machine learning packages, Python is a top pick.

## When to use R?

If your project is statistics-heavy, R programming is a better candidate for the task. R is also an excellent choice for narrow problems that require a one-time dive into a dataset. For example, if you’d like to analyze a corpus of text by deconstructing paragraphs into words or phrases and identifying patterns, R is a top pick. (Source: python vs R for data science)
