Difference Between Data Science and Machine Learning
Data Science is the study of data cleansing, preparation, and analysis, while machine learning is a branch of AI and subfield of data science. Data Science and Machine Learning are the two popular modern technologies, and they are growing with an immoderate rate. But these two buzzwords, along with artificial intelligence and deep learning are very confusing term, so it is important to understand how they are different from each other. In this topic, we will understand the difference between Data Science and Machine Learning only, and how they relate to each other.
Data Science and Machine Learning are closely related to each other but have different functionalities and different goals. At a glance, Data Science is a field to study the approaches to find insights from the raw data. Whereas, Machine Learning is a technique used by the group of data scientists to enable the machines to learn automatically from the past data. To understand the difference in-depth, let's first have a brief introduction to these two technologies.
Note: Data Science and Machine Learning are closely related to each other but cannot be treated as synonyms.
What is Data Science?
Data science, as its name suggests, is all about the data. Hence, we can define it as, "A field of deep study of data that includes extracting useful insights from the data, and processing that information using different tools, statistical models, and Machine learning algorithms." It is a concept that is used to handle big data that includes data cleaning, data preparation, data analysis, and data visualization.
A data scientist collects the raw data from various sources, prepares and pre-processes the data, and applies machine learning algorithms, predictive analysis to extract useful insights from the collected data.
For example, Netflix uses data science techniques to understand user interest by mining the data and viewing patterns of its users.

What is Machine Learning?
Machine learning is a part of artificial intelligence and the subfield of Data Science. It is a growing technology that enables machines to learn from past data and perform a given task automatically. It can be defined as:
Machine Leaning allows the computers to learn from the past experiences by its own, it uses statistical methods to improve the performance and predict the output without being explicitly programmed.
The popular applications of ML are Email spam filtering, product recommendations, online fraud detection, etc.
