#### Description

The course â€śMachine Learning Basics: Building a Regression model in Râ€ť teaches you all the steps of creating a Linear Regression model, which is the most popular Machine Learning model, to solve business problems.

Below is a list of popular FAQs of students who want to start their Machine learning journey-

**What is Machine Learning?**

Machine Learning is a field of computer science that gives the computer the ability to learn without being explicitly programmed. It is a branch of artificial intelligence based on the idea that systems can learn from data, identify patterns and make decisions with minimal human intervention.

**What is the Linear regression technique of Machine learning?**

Linear Regression is a simple machine learning model for regression problems, i.e. when the target variable is a real value.

Linear regression is a linear model, e.g. a model that assumes a linear relationship between the input variables (x) and the single output variable (y). More specifically, y can be calculated from a linear combination of the input variables (x).

When there is a single input variable (x), the method is referred to as simple linear regression.

When there are multiple input variables, the method is known as multiple linear regression.

**Why learn the Linear regression technique of Machine learning?**

There are four reasons to learn Linear regression technique of Machine learning:

1. Linear Regression is the most popular machine learning technique

2. Linear Regression has a fairly good prediction accuracy

3. Linear Regression is simple to implement and easy to interpret

4. It gives you a firm base to start learning other advanced techniques of Machine Learning

**How much time does it take to learn the Linear regression technique of machine learning?**

Linear Regression is easy but no one can determine the learning time it takes. It depends on you. The method we adopted to help you learn Linear regression starts from the basics and takes you to an advanced level within hours. You can follow the same, but remember you can learn nothing without practicing it. The practice is the only way to remember whatever you have learned. Therefore, we have also provided you with another data set to work on as a separate project of Linear regression.

**What are the steps I should follow to be able to build a Machine Learning model?**

You can divide your learning process into 4 parts:

Statistics and Probability â€“ Implementing Machine learning techniques require basic knowledge of Statistics and probability concepts. The second section of the course covers this part.

Understanding of Machine learning â€“ the Fourth section helps you understand the terms and concepts associated with Machine learning and gives you the steps to be followed to build a machine learning model

##### Programming Experience â€“ A significant part of machine learning is programming. Python and R stand out to be the leaders in recent days. The third section will help you set up the R environment and teach you some basic operations. In later sections, there is a video on how to implement each concept taught in theory lecture in R

Understanding of Linear Regression modeling â€“ Having a good knowledge of Linear Regression gives you a solid understanding of how machine learning works. Even though Linear regression is the simplest technique of Machine learning, it is still the most popular one with fairly good prediction ability. The fifth and sixth section covers Linear regression topic end-to-end and with each theory, lecture comes a corresponding practical lecture in R where we run each query with you.

**Why use R for data Machine Learning?**

Understanding R is one of the valuable skills needed for a career in Machine Learning. Below are some reasons why you should learn Machine learning in R

1. Itâ€™s a popular language for Machine Learning at top tech firms. Almost all of them hire data scientists who use R. Facebook, for example, uses R to do behavioral analysis with user post data. Google uses R to assess ad effectiveness and make economic forecasts. And by the way, itâ€™s not just tech firms: R is in use at analysis and consulting firms, banks and other financial institutions, academic institutions and research labs, and pretty much everywhere else data needs analyzing and visualizing.

2. Learning the data science basics is arguably easier in R. R has a big advantage: it was designed specifically with data manipulation and analysis in mind.

3. Amazing packages that make your life easier. Because R was designed with statistical analysis in mind, it has a fantastic ecosystem of packages and other resources that are great for data science.

4. A robust, growing community of data scientists and statisticians. As the field of data science has exploded, R has exploded with it, becoming one of the fastest-growing languages in the world (as measured by StackOverflow). That means itâ€™s easy to find answers to questions and community guidance as you work your way through projects in R.

5. Put another tool in your toolkit. No one language is going to be the right tool for every job. Adding R to your repertoire will make some projects easier â€“ and of course, itâ€™ll also make you a more flexible and marketable employee when youâ€™re looking for jobs in data science.

**What is the difference between Data Mining, Machine Learning, and Deep Learning?**

Put simply, machine learning and data mining use the same algorithms and techniques like data mining, except the kinds of predictions vary. While data mining discovers previously unknown patterns and knowledge, machine learning reproduces known patterns and knowledgeâ€”and further automatically applies that information to data, decision-making, and actions.

Deep learning, on the other hand, uses advanced computing power and special types of neural networks and applies them to large amounts of data to learn, understand, and identify complicated patterns. Automatic language translation and medical diagnoses are examples of deep learning.

**Whatâ€™s special about this course?**

The course is created based on three pillars of learning:

**Know (Study)****Do (Practice)****Review (Self-feedback)**

*Know*

We have created a set of concise and comprehensive videos to teach you all the Regression related skills you will need in your professional career.

**Do**

We also provide **Exercises** to complement the learning from the lecture video. These exercises are carefully designed to further clarify the concepts and help you with implementing the concepts on practical problems faced on-the-job.

**Review**

Check if you have learned the concepts by executing your code and analyzing the result set. Ask questions on the discussion board if you face any difficulty.

The Authors of this course have several years of corporate experience and hence have curated the course material keeping in mind the requirement of Regression analysis in todayâ€™s corporate world.
