Table of Contents
If you ask a layman with just a cursory understanding of technology, to explain Artificial Intelligence, they would certainly link it to robots. However, an AI researcher would define it in this way. Artificial Intelligence can be considered as a collection of algorithms that has the ability to generate results without us having to instruct it how to do exactly the same.
In fact, we can consider both the answers as right, but in their own ways. Let’s try to summarize the definition. Artificial Intelligence is:
- An intelligent entity created by us (humans).
- It is capable of performing and carrying out tasks intelligently and we don’t even have to instruct it to do so.
- It is capable of acting and thinking humanely and rationally.
It’s an integral branch of CS/IT that aims to clone human intelligence in robotic machines. Robots, machines, or more commonly, AI systems are powered with advanced machine learning and deep learning algorithms that make machines intelligent. However, the definition of AI has certainly altered in recent years. Earlier, even a simple function to perform calculations inside a calculator would have been considered to be an AI component. However, now, it’s just a mere computer program. Let’s understand how the various levels of AI exist.
Here’s a guide that will give you better insights into Artificial Intelligence.
Predominantly, we can categorize AI systems into 3 different levels. They are -
- Artificial Narrow Intelligence - This is also known as weak or narrow AI because it’s goal-oriented and designed to perform low-level simple tasks. Technologies such as Siri, Alexa, etc. fall under this category. It’s carried out through machine learning which specializes in only a particular area and solves that particular problem.
Artificial General Intelligence - Also referred to as deep or strong AI, where machines can mimic human intelligence. A few of its properties include recognition, hypothesis testing, analogy, etc. Speech and facial recognition systems generally fall under this category. However, this category is still under heavy research and is not completely developed yet.
Artificial Super Intelligence - It is just a vague concept. It’s supposed to develop in the coming future. It should be able to create and formulate its own set of emotions, do tasks more efficiently than humans in fields such as calculations, sports, art, etc.
Here’s a detailed guide explaining the different types of AI.
Why should you learn Artificial Intelligence?
From a technical standpoint, the primary aim of AI is to assist human abilities and allow us to make exceptional choices with unimaginable outcomes. AI is used in almost all the popular automated tools that we created decades ago to improve their performance and make calculated decisions to produce better outcomes. Let’s take a sneak-peek at a few motives that will help you understand why you should learn Artificial Intelligence right away.
