Data Science or Machine Learning: What Should One Learn First?


If you are confused about answering which technology to learn first, whether to go with Data Science or Machine Learning, you have landed at the right page. The article will clear all your doubts to give you a better understanding of both the technologies.


If you are deeply indulged in the tech world, the terms Data Science and Machine Learning have never escaped your attention. If you are thinking of learning and developing new skills, both the technologies have their own career scopes.

According to the Gartner report, “Out of the 10 lakh registered organizations in India, 75% have invested or are planning to invest in Data Science and Machine Learning”. So there shouldn’t be the second thought about learning these revolutionizing technologies.

There are top platforms like Global tech Council that offers data science certification and Machine Learning certification training and courses, making you ready for an industrial revolution.

Data Science vs. Machine Learning

Before understanding what one should learn first, let’s figure out what are the differences between the two most heard technologies of 2020. As these terms often overlap, to have a clear idea about the two is crucial.

What is Machine Learning (ML)?

ML is an application of Artificial Intelligence, where machines can learn by themselves without explicitly programmed. As machine learning is a subset of AI, it enables systems to learn and improve automatically. It makes software applications more accurate and precise in predicting outcomes.

The best example of this technology is customer-based product recommendations based on one’s past experiences. Facebook, Amazon, Netflix, and other top companies are using ML algorithms for customer-based product recommendations, real-time analysis, and for other various purposes.

Data Science

It is a concept that is used to handle big data. It is a mixture of various algorithms, tools, and ML algorithms to discover hidden patterns from unstructured data.  A data scientist is one who gathers data from multiple sources and applies ML algorithms to collect critical information that is beneficial for organizations.  

From the above definitions, it is clear that the significant point of difference between both the technologies is that Data Science generates insights, and ML produces predictions. We can say that ML is an integral part of the Data Science as Data Science makes use of ML, for analyzing data and future predictions.
