The demand for skilled data science professionals is ever increasing. The number of courses offered by universities as well as private institutes in collaboration with universities or corporate bodies has increased manifold over the decade. While there are a lot of free online resources that can help you acquire a tonne of information about data science and various tools and techniques involved in it, you will need to undergo a well curated, professional course in order to make the most of your time and to become truly ready for the industry. This post will help you understand what sort of courses you should enrol for in order to become a 360 degree data science expert.
There are certain areas of knowledge which you should be comfortable with even before starting with the most basic course related to data. Remember that everything you will do as a data science professional has its roots in statistics. So, being conversant with the fundamental ideas of statistics is an important prerequisite.
Although you can pick up a programming language along the way while learning data science, knowing one beforehand definitely puts you in an advantageous position.
Even though data science using python and data analytics are considered to be typically technical roles and maximum number of aspirants come from a STEM background, a good number of people from social sciences, biosciences, and economics, are participating in the data revolution.
Now, let us look at some courses that will set you up as a data science professional from scratch.
- Certified big data course
You should always start with a course that allows you to explore the basics of the field. A big data certification course can afford you a chance to get an overview of the discipline while also training you to use database management tools, data mining techniques, and some visualization techniques. This course should cost you something between Rs 30,000 to Rs 40,000 in India.
- Data visualization course
Your next stop should ideally be a data visualization course. These usually have short curriculums involving tools like Tableau. Not only do you learn different methods of presenting data to the stakeholders, you also acquire a sort of storytelling skill which is a basic necessity in the professional career of a data science professional. A data visualization course using Tableau from a reputed institute can cost anything between Rs 15,000 and Rs 25,000.
- Data science using Python
Right now Python is the undisputed leader in the race of programming languages. It has brilliant libraries for data science operations. But you need to spend a good amount of time learning the use of Python for data science. In this course you learn to use various modules in Python to achieve data science goals. In fact, Python is frequently used in tandem with the Hadoop ecosystem. In this respect you should read more about why companies use Hadoop with Python. This course should not cost you more than Rs 20,000 in India.
- Machine learning course
The logical move would be towards machine learning since data analysts and data science professionals are deploying machine learning models to do a lot of work in terms of data preparation and pattern identification. You cannot expect to become a full stack data science professional without a well founded proficiency in machine learning. A machine learning course would cost you around Rs 20,000 in India.
- Deep learning with Python
In this course you will learn a different set of Python libraries that will help you set up deep neural networks for processes like textual analysis, computer vision, speech and image recognition. This course will cost you something around Rs 25,000 from the best data science institutes in India.
After you have completed all these courses (by completion I mean sincerely going through all video content; attending all live sessions; completing all assignments without plagiarism) that is after you have spent around 600 hours and nearly 80,000 rupees (much less if you are lucky enough to get discounts), you will be able to call yourself a data science allrounder. In fact, with the machine learning and deep learning training you can actually make a move towards being a full stack Applied AI developer. The point is you need a plan of action before you jump into the field to find work. One course or one certificate does not cut it in the industry any more. The best combination will lead you to the best jobs.
