What is Artificial Intelligence?

In this post, you’ll learn more about Artificial Intelligence (AI) which has a wide-ranging branch of computer science concerned with building smart machines capable of performing tasks that typically require human intelligence. Understanding how Artificial Intelligence works will enable you to create GUIs with Python Windows GUI Builder with ease.

 

Why is Artificial Intelligence Important?

AI is important because it can give enterprises insights into their operations that they may not have been aware of previously. And more importantly, in some cases, AI can perform tasks better than humans.

AI tools often complete jobs quickly and with relatively few errors when it comes to repetitive, detail-oriented tasks like analyzing large numbers of documents to gain insights, make decisions, risk management, and complete specific tasks or actions.

 

Relation between Artificial Intelligence, Machine Learning, Neural Networks, and Deep Learning?

Here is a good analogy created by IBM [1]:

“Perhaps the easiest way to think about Artificial Intelligence, Machine Learning, Neural Networks, and Deep Learning is to think of them like Russian nesting dolls. Each is essentially a component of the prior term.”

Or, in other words: Machine Learning is a subfield of Artificial Intelligence. Deep Learning is a subfield of Machine Learning, and Neural Networks make up the backbone of Deep Learning algorithms. The number of node layers, or depth, of neural networks that distinguishes a single neural network from a deep learning algorithm, which must have more than three.

 

Why use Python for AI?

AI requires a foundation of specialized hardware and software for writing and training Machine Learning algorithms. No one programming language is synonymous with AI, but a few, including Python, R and Java, are popular.

In this article, we will limit our tutorial only for implementation of Python for AI/ML. The reason why Python implementations are so popular, because of its easy to use, popular, mature, and community supported AI/ML libraries.
