Artificial Intelligence vs Machine Learning

We often hear about artificial intelligence and machine learning, two terms that have the latest technological revolutions as their common denominator.

But what is artificial intelligence and what is different from machine learning?

Artificial Intelligence vs. Machine Learning: How Are They Different?

To answer this question we must begin by describing the two technologies separately.

First of all, it is good to immediately point out that, although they are closely connected to each other, artificial intelligence and machine learning are not the same thing. It would be more correct to define them as two sides of the same coin.

Artificial intelligence, in fact, is the science that for years has been aiming to develop machines capable of making decisions in perfect autonomy. The thought immediately runs to the robots. Advanced learning, on the other hand, is the algorithm that makes computers even more intelligent. We try to see in detail what the real differences between these concepts are. Read on!

Artificial Intelligence vs. Machine Learning: Basic difference

More and more often we hear of artificial intelligence, but also of machine learning, the latter term sometimes used improperly as synonyms of the first.

The term “artificial intelligence” (AI or IA) was coined for the first time in the 1950s and involves all those computational machines capable of performing tasks characteristic of human intelligence machine learning  is simply a way to reach artificial intelligence.

What is Artificial intelligence (AI)?

Have you still not understood?

Well, more concrete examples will help to better understand the two concepts.

Artificial intelligence could be defined as the science that develops the architecture necessary for machines to function like the human brain. Have you ever heard of neural networks?

It is a computer system that tries to simulate biological neuronal networks.

The final objective of AI (artificial intelligence) is, as anticipated, to create computers with reasoning abilities similar (if not equal) to human beings.

Read more about AI

What is Machine learning (ML)?

Machine learning, on the other hand, is an algorithm that allows intelligent machines to improve over time, exactly as it does with the human brain.

Without advanced learning, in fact, it would not be possible to put artificial intelligence into motion. Let’s take an example. Autonomous driving cars are based on both artificial intelligence and advanced learning.

Machine learning allows the car to remember the road traveled or to recognize and avoid the obstacles encountered previously.

In short, thanks to advanced learning, computers with artificial intelligence learn.

Read more about ML

What are the similarities between Machine Learning and Artificial Intelligence?

  • Both can be used to build sophisticated systems to perform certain tasks.
  • Both are based on statistics and mathematics.
  • Machine Learning is the new cutting-edge technology of Artificial Intelligence.

What is the difference between Machine Learning and Artificial Intelligence?

Machine Learning vs Artificial Intelligence

Machine Learning is a type of Artificial Intelligence that allows a computer to learn without being explicitly programmed.

Use an algorithm to analyze data, learn from it and make decisions accordingly.

Artificial intelligence is the theory and development of computer systems capable of intelligently performing tasks similar to a human being.
Focus on machine learning for precision and models. Artificial intelligence focuses on intelligent behavior and the maximum chance of success.
Machine learning can be divided into categories to supervise learning, supervision less learning and reinforcement learning. Applications based on artificial intelligence can be classified as applied or general.


The Artificial Intelligence’ has become part of our lives every day: we exploit every day, perhaps unconsciously, when we use a search engine, while we buy something on the Internet, and take a photograph with a mobile phone, while dictating by voice a text message, etc.

Machine learning has recently achieved remarkable milestones in relation to artificial intelligence.

Enormous amounts of data collected from countless sensors on the Internet of Things improve and will continue to improve AI more and more.

Artificial Intelligence future

The ultimate guide on Artificial Intelligence

When it comes to Artificial Intelligence, we immediately think of cutting-edge technologies, robots that understand and decide what actions to take and a futuristic world in which machines and men live together.

In reality, Artificial Intelligence and its use are much more real than can be imagined and are now used in different areas of everyday life.

However, these are less invasive uses of what is thought or what is often shown by science fiction films that have found in the theme of Artificial Intelligence the starting point for many more or less successful series.

What is Artificial Intelligence?

AI is a subdivision of computer science dealing with the development of systems and software capable of acting intelligently, and doing things that would normally be done by people – equally as well, or sometimes better.

AI refers to the science and methodology itself, and to the behavior exhibited by the machines and programs which result from it.

The term was first introduced during The Dartmouth Conference of 1956, by Stanford University researcher John McCarthy.

In its practical applications since then, three distinct approaches to AI have evolved.

There are the big AI companies that are using artificial intelligence to shape the connected future like Amazon, Apple, Facebook, Google, IBM, Intel, Microsoft, Twitter, Qualcomm, OpenAI, Nvidia, Netflix and more.

Strong AI

Machines and applications in this field are designed to simulate the functions of actual human intelligence – to think as we think. Systems may also have the ability to explain why humans think the way they do.

The “Holy Grail “of this approach is to create machines that are artificial simulations of human consciousness – a level that we’re some way distant from.

Weak AI

The products of this philosophy are functioning systems and software that do things that humans do – but not necessarily in the same way.

Weak AI machines may behave like people on the surface, but they can’t reveal how humans think. An example of this would be the chess-playing capabilities of IBM’s Deep Blue.

How it is helping the people in daily life

Artificial intelligence is not just a term in fashion: today its influence on our daily life is greater than ever. Whether you are reading emails or looking at the Netflix catalog, artificial intelligence makes decisions to improve our user experience based on our preferences, inclinations, and behaviors.

AI has been instrumental in driving innovation in areas such as medicine, research, language, cars and of course advertising. Here’s how artificial intelligence affects our daily lives.


AI has dramatically changed the future of driving and cars. Self-driving vehicles can deal with an almost infinite number of scenarios.

These smart cars make accidents caused by less likely human errors and can even automatically change settings based on the owner’s preferences, such as turning on seat heating on a cold winter night.


Applications such as Waze evaluate traffic and road works to find the fastest route to your destination, all thanks to AI.

Navigation services make these assessments based on this type of element every time a command is given. And this also happens in the case of ride-sharing services.


Machine learning, a subset of AI, is greatly influencing the way we treat and communicate with patients at every stage of interactions with them.

The ML is used to analyze imaging exams, search for tumors and make diagnoses using pathologist reports.

AI plays an important role in detecting potential symptoms and has proved more efficient than the manual processes that were used before.

Chat-bots, which can help to find patterns in the patient’s symptoms, and facial recognition software, are combined with deep learning to help identify rare genetic diseases.

Machine Learning

Moreover, the different techniques of learning and developing algorithms give rise to as many possibilities of use that widen the field of application of machine learning to make a specific definition difficult.

However, we can say that when we talk about machine learning, we talk about different mechanisms that allow an intelligent machine to improve its capabilities and performance over time.

What are the career aspects of Artificial Intelligence?

The careers in artificial intelligence (AI) have grown and it is expected that this industry will contribute more to job creation in the future.

According to Digital Transformation Institute, the growth will be increased by 2.3 million positions in 2030.

Let’s take a closer look if careers in the AI industry entice you i.e. machine learning engineer, data scientists, video game programmer, robotics programmer, data mining analyst, software engineer, business intelligence developer, research scientist and big data engineer/architect.

Even the median annual salary of AI professional is whopping $100,000 to $150,000.

There’s a lot of buzzes that makes it hard to tell what science is and what science fiction is. Let’s get into it!

What is Machine Learning?

When it comes to machine learning it comes to a particular branch of computer science that can be considered a close relative of ‘ artificial intelligence.

Defining in a simple way the characteristics and applications of machine learning are not always possible since this branch is very vast and includes different methods, techniques, and tools to be realized.

Moreover, the different techniques of learning and developing algorithms give rise to as many possibilities of use that widen the field of application of machine learning to make a specific definition difficult.

However, we can say that when we talk about machine learning, we talk about different mechanisms that allow an intelligent machine to improve its capabilities and performance over time.

Machine Learning Examples in everyday life:

When we talk about machine learning, we often think only of applications in super-specific fields, in areas of research in science and medicine, space engineering or other branches not commonly understood by ordinary people.

This is a very common mistake, as machine learning presents many everyday applications.


What applies to marketing which has an even more important meaning in science?

The intelligent processing of big data considerably lightens the work of empirical research.

For example, thanks to self-learning systems, particle physicists can detect and process much more data and detect any anomalies. But machine learning can also be helpful in medicine.

Nowadays some doctors use artificial intelligence to make diagnoses and therapies. Furthermore, machine learning is also useful for the prognosis of diabetes or heart attacks.


Nowadays robots are now everywhere especially in factories: for example, they are used in mass production to automate ever-changing work steps.

However, these are not really intelligent systems, since they are only programmed to perform a single specific step. When self-learning systems are used in robotics they must be able to solve new tasks.

Naturally, these advances are of great interest also for other sectors: from space travel to domestic work, robots with artificial intelligence can take action in many areas.


The autonomous cars are a great showcase for machine learning.

Only automatic learning means that cars move independently and safely in traffic, instead of only in the test routes.
Since it is not possible to program all possible situations, autonomous vehicles must refer to intelligent machines.

For example in the form of artificial neural networks, analyze traffic and develop more efficient ways of managing it, such as by intelligently switching traffic lights.

Personal assistants

Even in their own four walls, smart computers are becoming more and more present: this is how normal homes become smart homes.

The Moley Robotics Company, for example, develops an intelligent kitchen equipped with mechanical arms that prepare meals.

Even personal assistants such as Google Home and Amazon Echo, thanks to which you can monitor systems and devices in your home, use machine learning technologies to better understand the needs of their users.

E commerce

E commerce is a virtual market place and using Machine Learning algorithms to understand the users behavior and interest. The technologies is growing along with the demand and new techniques of delivering product and service. E commerce is one of them emerging technologies using Machine Learning and AI.


Since the beginning of research on artificial intelligence, the ability of machines to play has always been a great stimulus for researchers.

The self-learning systems were put to the test in chess, checkers and even go the well-known Chinese board game among the most complex in the world, challenged by human competitors.

Video game developers also use machine learning to create more appealing projects.

Game designers can use machine learning to create a more balanced game experience possible and to make virtual opponents better adapt to the behavior of human players.

What are the career aspects of Machine Learning?

As mentioned above, Machine learning increases the performance of the machine and reduces the human efforts that in turn enable them to learn for themselves. So, there are career aspects of machine learning which are given below:

  • Machine Learning Engineer
  • Data Scientist
  • NLP Scientist
  • Business Intelligence Developer
  • Human-Centered Machine Learning Designer
