“The World is One Big Data Problem” – Andrew McAfee.

Analytics Vidhya is back with its 19th Edition of the Data Science Blogathon which is live from TODAY! So the wait is over, click here to Register Now!

 

Introduction

The Data Science Blogathon by Analytics Vidhya began with a simple mission: To bring together a large community of data science enthusiasts to share their knowledge with the world. With 4000+ articles under our belt on various topics such as Data Science, Machine Learning, Deep Learning, Data Lakes, and Data Engineering published by over 700 authors who are avid data science enthusiasts, students, professionals and researchers from across the globe. We bring to the 19th edition of the Data Science Blogathon, this time with a new reward.

What’s in it for You?

This month’s Data Science Blogathon brings you more rewards for you through our special referral programme. That’s right! 

Introducing the Author Referral Program!

Yes, you read that right! Refer and encourage your friends to publish articles in the current Blogathon and both of you stand a chance to win an extra amount.

Who can participate in the Referral Program?

This program is only open to all our existing authors.

Reward

  • Refer a friend and if the referee publishes 1 article then both referrer and referee will receive INR 300 each.
  • Refer a friend and if the referee publishes 3 or more articles then both referrer and referee will receive INR 1300 each.

How?

  • The referral code is shared with existing authors over the mail
  • Share your referral code with your friends (ONLY NEW AUTHORS are eligible for the code who would be publishing their articles for the first time on Analytics Vidhyas’ blog).
  • Tell them to submit the code at the time of registration

 

Though you still might be wondering, apart from the monetary rewards, what else is there to learn for you?

Implement your Learnings

Be the master of your data science learnings and transcribe them for the world to read. Learning and writing go hand-in-hand, and jotting down your thoughts not only enhances retention of what you have learned but also serves for future reference.  

Boost Structured Thinking

A good data scientist knows how to code. But, a great data scientist knows precisely how to approach each problem with a structured thinking mindset and the ability to storyboard. Working closely on problem statements and the habit of writing about your possible solutions gives you the edge over every other coding master.  

Build up your Resume 

Writing blogs and getting them published not only serves as a great learning experience but also boosts your visibility in the massive crowd of data scientists like you out there. 

Analytics Vidhya’s Data Science Blogathon is the second largest of its kind in the world, and every article published is shareable on popular hiring websites and job boards like LinkedIn, Monster.com, Shine, etc. 

Get Noticed in the Analytics Vidhya Community

While gaining knowledge through the process of blog writing is important but getting a chance to network with industry leaders and like-minded people is priceless. Analytics Vidhya has 2.5 million monthly users including industry experts so there’s a good chance of reaching potential employers for your dream role. 

Cash Rewards are at stake! 

Learning, networking and recognition are all well and good but we have cash rewards for the best writers out there, with a new writing category and a surprise reward on offer as well. Do read on for more information about the rewards. 

What are the Prizes on the Offer?

Choose the topic of interest for Data Science and get rewarded for each published article. Just like always, everyone stands a chance to win based on the unique page views each article attracts. The more submissions you have, the better are your chances of landing a lucrative cash reward. 

Special Topics: Data Engineering

This time around, we are considering all topics that come under Data Engineering as Special Topics and are eligible for mega cash rewards for Analytics Vidhya Creators Club members and non-members as well. Here are some of the suggested topics:

Some important things to note:

  • Publish 3 or more articles in any Data Science Blogathon and automatically become a part of the Analytics Vidhya Creators’ Club to avail exciting benefits and prizes!
  • Starting on 8th April 2022, all existing and new members of the AVCC will have complementary 30 days of access to our Amazon Web Services (AWS) course.
  • Note that the article will have to be technical and code-based in nature to be eligible for the above special categories. Listicles or career articles will not count. 
  • All International Payments will be made via PayPal. 

Judgement Criteria

  • The top 3 articles will be judged based on the number of unique page views for each article.
  • The top 3 Guides will be judged by the Editorial team at Analytics Vidhya.

Mega Cash Rewards

That’s not All, More Prizes!

Data Science Blogathon 19

A New Submission Category-Guides

Just like Blogathon 18, we continue to publish Guides, but this time, there are more rewards for Guide Writers. The objective of a Guide is to serve as a one-stop repository of resources and help related to specific topics in Data Science, Machine Learning and other related topics. Guides help the community to learn and grow, and help you to process and transcribe your learnings in a concise, structured written piece. Since we receive multiple entries from our guide writers, we publish only one guide per topic. Some of the suggested topics are given below:

Data Science Blogathon 19

Here is an example of a Guide: K Means Clustering | K Means Clustering Algorithm in Python

Feel free to explore any topic of your choice though – the only restriction is that it should be as comprehensive as possible and should be a minimum of 2500 words in length. It should also be on a topic in the domain of Machine Learning, Data Science, Deep Learning, Data Engineering, etc. 

Please note that the final consideration of a guide is an editorial decision that is based on how unique your Guide’s topic is and how comprehensively you have explained all components of that topic.

A Special Award Category: Win the New iPad!

You are not in a dream. Every author whose article gets published in the blogathon stands a chance to win the latest iPad through a random draw, where one lucky winner will be chosen. 

iPad | Data Science Blogathon

This is an opportunity that should not be passed upon. You stand a chance to get your hands on the latest iPad with striking fast performance and an outstanding display. Think of the amount of learning you would be able to achieve on this powerful device from Apple. 

How to Participate?

To participate, simply click on the “Register Now” button above to be redirected to the registration portal. Fill out some basic details, and once the competition starts on 8th April 2022, sign in to https://editor.analyticsvidhya.com/ and start writing. It’s that simple!

Important Dates and Deadlines

Note: We update the leaderboard twice a day. There is no set time for the update per se. But check back in the afternoon and late evening to see the latest views.

I am a passionate writer and avid reader who finds joy in weaving stories through the lens of data analytics and visualization. With a knack for blending creativity with numbers, I transform complex datasets into compelling narratives. Whether it's writing insightful blogs or crafting visual stories from data, I navigate both worlds with ease and enthusiasm. 

A lover of both chai and coffee, I believe the right brew sparks creativity and sharpens focus—fueling my journey in the ever-evolving field of analytics. For me, every dataset holds a story, and I am always on a quest to uncover it.
