Difference Between Data Science And Machine Learning – In this article, I clarify the various roles of a data scientist and how data science compares and overlaps with related fields such as machine learning, deep learning, artificial intelligence, statistics, IoT, operations research, and applied mathematics. Since data science is a broad discipline, I begin by describing the different types of data scientists one might encounter in any business environment: you may even find yourself to be a data scientist without knowing it. As in any scientific discipline, data scientists can borrow techniques from related disciplines, although we have developed our own arsenal, particularly techniques and algorithms for handling very large unstructured data sets in automatic ways, even without human interactions, to perform transactions in real time or to make predictions.
To get started and gain some historical perspective, you can read my article on 9 Types of Data Scientists, published in 2014, or my article comparing data science to 16 analytics disciplines, also published in 2014.
Difference Between Data Science And Machine Learning
I also wrote about the ABCD of Business Process Optimization where D stands for Data Science, C for Computer Science, B for Business Science and A for Analytical Science. Data science may or may not involve coding or mathematical practice, as you can read in my article on low-level vs. high-level data science. In a startup, data scientists generally wear several hats, such as CEO, data miner, data engineer or architect, researcher, statistician, modeler (as in predictive modeling), or developer.
Data Science And Artificial Intelligence Difference?
While a data scientist is generally depicted as a coder experienced in R, Python, SQL, Hadoop and statistics, this is only the tip of the iceberg, popularized by data camps that focus on teaching some elements of data science. But just as a lab technician can be called a physicist, a real physicist is much more than that, and her domains of expertise are diverse: astronomy, mathematical physics, nuclear physics (which is borderline chemistry), mechanics, electrical engineering, signal processing (also a sub-field of data science) and more. The same can be said for data scientists: fields are as diverse as bioinformatics, information technology, simulations and quality control, computational finance, epidemiology, industrial engineering, and even number theory.
In my case, for the last 10 years, I have specialized in machine-to-machine and device-to-device communication, developing systems for automatic processing of large data sets, for performing automated transactions: for example, buying Internet traffic or automatically generating content. It involves the development of algorithms that work with unstructured data and is at the intersection of AI (Artificial Intelligence, ) IoT (Internet of Things, ) and data science. This is called deep data science. It is relatively math-free and involves relatively little coding (mostly APIs), but is quite data-intensive (including building data systems) and is based on brand new statistical technology designed specifically for this context.
Before that, I worked on real-time credit card fraud detection. Earlier in my career (circa 1990) I worked on remote sensing imaging technology, among other things to identify patterns (or shapes or features, eg lakes) in satellite images and perform image segmentation: at that time my research was labeled computational statistics, but the people doing the same thing in the computer science department next door to my home university called their research artificial intelligence. Today, it would be called data science or artificial intelligence, with subdomains being signal processing, computer vision, or IoT.
Also, data scientists can be found anywhere in the life cycle of data science projects, from the data collection or data exploration phase to statistical modeling and maintenance of existing systems.
Comparison Between Machine Learning Vs Data Science Vs Data Analyst
Before we dive deeper into the relationship between data science and machine learning, let’s briefly discuss machine learning and deep learning. Machine learning is a set of algorithms that are trained on a set of data to make predictions or take actions in order to optimize some system. For example, supervised classification algorithms are used to classify potential customers as good or bad prospects, for loan purposes, based on historical data. The techniques involved, for a given task (eg, supervised clustering), are different: naive Bayes, SVM, neural networks, ensembles, association rules, decision trees, logistic regression, or a combination of many.

All this is a subset of data science. When these algorithms are automated, as in automated piloting or driverless cars, it’s called AI, and more specifically, deep learning. Click here for another article comparing machine learning to deep learning. If the collected data comes from sensors and if it is transmitted over the Internet, then it is machine learning or data science or deep learning applied to IoT.
Some people have a different definition of deep learning. They consider deep learning as neural networks (a machine learning technique) with a deeper layer. The question was asked on Quora recently, and below is a more detailed explanation (source: Quora)
This article tries to answer the question. The author writes that statistics is machine learning with confidence intervals for quantities that are predicted or estimated. I tend to disagree, as I have constructed engineer-friendly confidence intervals that do not require any mathematical or statistical knowledge.
Data Science Vs Machine Learning
In machine learning means that the algorithms depend on some data, which is used as a training set, to fine-tune some parameters of the model or algorithm. This covers many techniques such as regression, naive Bayes or supervised clustering. But not all techniques fit into this category. For example, unsupervised clustering—a statistical and data science technique—aims to discover clusters and cluster structures without any a priori knowledge or training set to aid the classification algorithm. A human being is required to label the clusters found. Some techniques are hybrid, such as semi-supervised classification. Some pattern detection or density estimation techniques fit into this category.
However, data science is much more than machine learning. Data, in data science, may or may not come from a
Or mechanical process (research data may be collected manually, clinical trials involve a specific type of small data) and may have nothing to do with
As I have just discussed. But the main difference is the fact that data science covers the whole spectrum of data processing, not just the algorithmic or statistical aspects. In particular, data science also covers

Data Analyst Vs. Data Scientist: Which Should You Pursue?
People have been trying to define data science for over a decade, and the best way to answer the question is through a Venn diagram. Created by Hugh Conway in 2010, this Venn diagram consists of three circles: mathematics and statistics, subject matter expertise (knowledge of the domain to be abstracted and computed), and hacking skills. Basically, if you can do all three, you are already very knowledgeable in the field of data science.
Data science is a concept used to deal with big data and involves cleaning, preparing and analyzing data. A data scientist gathers data from multiple sources and applies machine learning, predictive analytics, and sentiment analysis to extract critical information from collected data sets. They understand data from a business perspective and can provide accurate predictions and insights that can be used to drive critical business decisions.
Anyone interested in building a strong career in this domain needs to acquire critical skills in three departments: analytics, programming, and domain knowledge. Going one level deeper, the following skills will help you carve out a niche as a data scientist:
