This article is an ultimate guide, crafted by the GATE experts at GFG, to help you start your journey of learning for GATE (Graduate Aptitude Test in Engineering) Data Science and AI in 100 Days in a systematic manner.


There are many overlaps when it comes to data science and artificial intelligence (AI). AI has many smaller subsets, like machine learning and deep learning. Data science uses these technologies to interpret and analyze data and find trends and patterns to make predictions. So, the choice between AI vs data science can be tricky.

Machine Learning (ML) depends on strong data science practices to get relevant data in training the ML algorithms and systems. Data science is a field that requires the knowledge of both Artificial Intelligence (AI) and Machine Learning (ML), and many AI careers, like an AI engineer, need the skills of a data scientist.

The demand for data science and AI skills is only increasing by the day. if you preparing for GATE 2024 or looking for a last 3-month preparation strategy?, this is the best place to get a roadmap of your Data Science and AI learning journey along with all the latest job-oriented technologies, designed according to the latest GATE Syllabus.

100 Days of GATE Data Science & AI – FAQs

1. Can I go into AI with data science?

Yes, you can go into AI with data science. If you have a background in data science, going into AI is a great idea as data science and AI are closely related fields. But first, you need to build a strong base in data science and AI fundamentals.

2. What is the roadmap for data science?

Here is a brief roadmap for data science:

  • Learn Python or R for programming and get a solid understanding of basic statistics and mathematics
  • Master data manipulation with Pandas and develop exploratory data analysis (EDA) skills.
  • Get hands-on experience with tools like Matplotlib for data visualization.
  • Understand fundamental machine learning algorithm and learn model evaluation metrics.
  • Understand hyperparameter tuningvery well.
  • Develop skills in creating meaningful features.
  • Then explore big data tools like Apache Spark.
  • Go deep into advanced machine learning and deep learning.
  • Choose a focus area like NLP or computer vision.
  • Apply your skills in real-world projects and build a portfolio on platforms like GitHub.
  • Stay updated with data science trends, read research papers and participate in communities.
  • Improve your communication and problem-solving skills.
  • Attend data science events and network with professionals for insights and opportunities.

3. How do I get started with data science and AI?

To get started with data science and AI, you need to start by mastering fundamental programming languages like Python. You also need to get a solid understanding of basic mathematics and statistics.

For a detailed answer, refer to Q2.

4. Is Data Science required for Artificial Intelligence?

Data science is closely related artificial intelligence (AI), and these two fields often intersect. Data science is not strictly required for Artificial Intelligence but it plays a key role in many AI applications.

5. Which is better- data science or machine learning?

There is no straightforward answer to this. This choice between data science and machine learning depends on your interests and career goals. Data science includes a broad range of activities, like exploring data, data analysis, and data interpretation to obtain insights while machine learning is a specialized field within data science that involves creating algorithms capable of learning from data and making predictions or decisions. While data science is about understanding and using data , machine learning is specifically focused toward creating predictive models. Both fields often overlap, and it is better to have a combination of skills from both data science and machine learning.
