Artificial Intelligence vs Machine Learning vs Deep Learning vs Data Science vs IoT? Are they the same or different?

We’re all familiar with the term “Artificial Intelligence.” After all, it’s been a popular focus in movies such as The Terminator, The Matrix, Transcendence etc. But you may have recently been hearing about other terms like “Machine Learning”, “Deep Learning”, “IoT” and even “data science”, sometimes used interchangeably with artificial intelligence.

One of the big confusions for many of the students out there is, what is the difference between Artificial Intelligence, Machine learning, Deep Learning, Data science and Internet of Things ? There is a lot of media hype about these terms and people use it interchangeably. As these terms are maturing today, there is not a concrete predefined definition for these terms. As a result, the difference between artificial intelligence, machine learning, deep learning, data science and Internet of Things can be very unclear. So let’s throw some light at what actually are these terms and how can they be differentiated from one another.

Artificial Intelligence (AI)

Artificial Intelligence (AI) in layman terms, enables a computer to think and take decisions accordingly. John McCarthy, who is known as the father of Artificial Intelligence first used the word AI in 1956 Dartmouth Conference, the first artificial intelligence conference and said “AI involves machines that can perform tasks that are characteristic of human intelligence”. In general, it includes things like planning, understanding language, recognizing objects and sounds, learning, and problem solving.

 We can put AI in two categories, weak AI and strong AI. Weak AI (also known as Narrow AI) exhibits some facet(s) of human intelligence, and can do that facet extremely well, but is lacking in other areas. A machine that’s great at recognizing images, but nothing else, would be an example of narrow AI. All currently existing systems considered artificial intelligence of any sort are weak AI at most. Applied AI also comes under weak AI. Siri is a good example of narrow intelligence and applied AI. Siri operates within a limited pre-defined range, there is no genuine intelligence, no self-awareness, no life despite being a sophisticated example of weak AI. Whereas a Strong AI develops artificial intelligence to the point where the machine's intellectual capability is functionally equal to a human's. The ideal Strong AI machine, would be built in the form of a man, have the same sensory perception as a human, and go through the same education and learning processes as a human child. Essentially, the machine would be "born" as a child and eventually develop to an adult in a way analogous to human development. Some of you may have heard of a TV series known as ‘Person of Interest” which showcased the capability of a strong AI and what It can do.

Machine Learning (ML)

Artificial Intelligence is a broad area. Machine learning is a subset of Artificial intelligence. Arthur Samuel coined the term “Machine Learning” in 1959, defining it as, “The ability to learn without being explicitly programmed.” Machine learning is the ability of a computer system to learn from the environment and improve itself from experience without the need for any explicit programming or hand coding. Machine learning focuses on enabling algorithms to learn from the data provided, gather insights and make future predictions. In very simple terms, machine learning can be thought of as the automation of predictive analytics.

There are three types of machine learning algorithms: supervised learning, in which data sets are labelled so that patterns can be detected and used to label new data sets; unsupervised learning, in which data sets aren't labelled and are sorted according to similarities or differences; and reinforcement learning, in which data sets aren't labelled but, after performing an action or several actions, the AI system is given feedback.

Deep Learning (DL)

Deep learning is a subset of machine learning and has taken shape since 2006. It uses artificial multi-layer neural networks. Neural Networks are inspired by our understanding of the biology of our brains – all those interconnections between the neurons. But, unlike a biological brain where any neuron can connect to any other neuron within a certain physical distance, these artificial neural networks have discrete layers, connections, and directions of data propagation. To put it in simple terms, deep learning is inspired by the structure and function of the brain, namely the interconnecting of many neurons and Artificial Neural Networks (ANNs) are algorithms that mimic the biological structure of the brain.

Deep Learning has enabled many practical applications of Machine Learning and by extension the overall field of AI. Deep Learning breaks down tasks in ways that makes all kinds of machine assists seem possible, even likely. Driverless cars, better preventive healthcare, even better movie recommendations, are all here today or on the horizon.

Data Science

Data Science is an interdisciplinary field of systems and processes to extract information from data in many forms. It covers a wide array of data-oriented technologies including SQL, Python, R, etc. It also makes extensive use of statistical analysis, data visualization, distributed architecture, etc. In simple terms, data science is the extraction of relevant insights from data by using various techniques from many fields like mathematics, machine learning, computer programming, statistical modelling, data engineering and visualization, pattern recognition and learning, uncertainty modelling, data warehousing, and cloud computing. Data Science does not necessarily involve big data, but the fact that data is scaling up makes big data an important aspect of data science.

Internet of Things (IoT)

There’s a lot of noise at the moment about the Internet of Things (or IoT) and its impact on everything from the way we travel and do our shopping to the way manufacturers keep track of inventory. But what is the Internet of Things? The Internet of Things (IoT) is the network of physical devices embedded with electronics, software, sensors, actuators, and connectivity which enables these things to connect and exchange data, creating opportunities for more direct integration of the physical world into computer-based systems, resulting in efficiency improvements, economic benefits and reduced human intervention.

In layman terms, the Internet of Things is the concept of connecting any device to the Internet and to other connected devices. The IoT is a giant network of connected things and people – all of which collect and share data about the way they are used and about the environment around them.

The relationship between AI (which includes ML and DL) and IoT is much like the relationship between the human brain and body. Our bodies collect sensory input such as sight, sound, and touch. Our brains take that data and makes sense of it, turning light into recognizable objects and turning sounds into understandable speech. Our brains then make decisions, sending signals back out to the body to command movements like picking up an object or speaking. Similarly, all of the connected sensors that make up the Internet of Things are like our bodies, they provide the raw data of what’s going on in the world. Artificial intelligence is like our brain, making sense of that data and deciding what actions to perform. And the connected devices of IoT are again like our bodies, carrying out physical actions or communicating to others.

The opportunity that lies -

Data science is the fundamental area of Artificial intelligence(AI), Machine learning(ML) and deep learning(DL). AI, ML and DL are all possible and exists today because of data science and hence these can be included as a subset of data science. Data science has a wide scope in almost every industry as each and every industry thrives for automation nowadays which is possible only by the integration Data science with AI, ML, DL and IoT. Machine learning and deep learning have led to huge leaps for AI in recent years. The next big thing can be seen in niche areas of Artificial Intelligence like Machine learning and deep learning and ultimately building a strong AI.

Those who still have some doubts left about the differences, an over simplified definition of these terms are as follows –
