This is a question that I get almost every day from people, especially students, who want to start their journey into Data Science. There is so much to learn and so much to do. The overwhelming amount of resources available on the internet today makes it messy for the beginners. There is no prescribed path to follow and they are afraid of getting lost in the woods.
So here is how I started my adventure a year ago. I’m not going to tell which courses to take up, because there are so many of them that you can choose the ones that suit you the best.
1. Introduction to Data Science
First and foremost, get to know what data science is all about, what a data scientist does, how it helps the businesses. Don’t dive right into the technical concepts. Familiarise yourself with descriptive, inferential, predictive, prescriptive statistics and how they drive business decisions.
2. Learning Python
The next step is to learn a programming language. There has always been a debate about Python vs. R. I chose the former, because it’s a general purpose programming language and can be used for anything like data science, web development, building games, etc.
3. Data Science Libraries
Next is to learn the data science libraries in Python like NumPy, Pandas, Matpotlib, Scipy, etc. and practice some data analysis and visualizations.
4. Machine Learning Basics
Then move on to getting comfortable with Machine Learning basics, including the theory and mathematics behind common algorithms.
5. Applied Machine Learning
Finally, get down to some coding in Python to build ML models and solve some real problems.
6. Explore, explore, and EXPLORE!
After the above steps, you will have a strong foundation in Python and Machine Learning. Now is the time to explore different sub-domains like Natural Language Processing, Computer Vision, Business Intelligence, etc. Pick up any project you like and study about it in detail. Keep your projects as vast as possible.
The sources I utilized in the same order as above:
This field is so vast and fast-paced, you will never get bored!
Hope this helps 🙂
I am an avid learner and never shy off from working hard or working till late. I am also a passionate reader, and love to read thriller novels, Jeffrey Archer being the favorite writer.
