Artificial Intelligence (AI) is changing everything around us and how we do business. It’s changing how we live and work.
To get started with artificial intelligence, it can be overwhelming, but if you take things one step at a time, you can learn artificial intelligence.
The purpose of this guide is to provide people with no prior knowledge of artificial intelligence with an easy-to-follow process for understanding and mastering its concepts.
The first part of this guide covers the fundamentals of artificial intelligence. This includes Machine Learning (ML) and Neural Networks (NN). Machine Learning and Neural Networks are two of the most important components of AI Technology.
In the second part of this guide, I will cover the basic requirements that are needed to begin your AI journey. The three main skill categories required are Mathematics, Programming, and Data Analysis.
While practical experience is important in AI learning, we’ll focus on gaining practical experience by working on your own projects or applying your knowledge to real-world problems.
We’ll also go over how to stay current with the latest developments in AI research and trends in the rapidly evolving field.
By the time we’re done, you will have a good understanding of AI that will allow you to explore other areas of AI study and potential job opportunities.
What Is Artificial Intelligence? Understanding the Basics
Artificial intelligence (AI) is a subdiscipline of computer science that focuses on creating intelligent machines — computers that can think for themselves. The focus of AI is on developing machines that can accomplish tasks and make decisions based on logic, learn, solve problems, and improve over time.
Unlike robots or other mechanical devices that mimic human actions, AI is focused on increasing efficiency and solving complex problems. As such, today AI plays an important role in many industries, including health care and finance.
To better understand how AI works, you should know that there are three primary objectives of artificial intelligence:
- Automation of Repetitive Work: AI can handle all repetitive work without becoming fatigued.
- Improvement of Problem-Solving Capabilities: The AI system assists with making sense of large amounts of data.
- Evolution of Adaptive Systems: AI systems can learn and improve over time.
These three objectives of AI are achieved by algorithms, which are the “instructions” given to machines. These instructions are used to process input data to make decisions or predictions. As technology advances, the importance of AI will grow. AI will continue to have a much greater impact on our lives, and understanding the basics of AI will be essential for anyone who wants to get more involved in this field.
Types of AI: Narrow, General, and Superintelligent
The three types of AI are defined by their functionality (i.e., what they do). The three types of AI are Narrow AI, General AI, and Superintelligent AI.
Narrow AI, also known as weak AI, performs a single function at a time. An example of narrow AI is a virtual assistant like Siri or a Netflix recommendation system. Narrow AI is excellent at performing that one function, but will never perform another type of function (the recommendation system will never assist you with your flight reservations), nor will it adapt to other functions.
General AI is the goal for future development. It wants to be able to do anything that a human can do intellectually. At this point, general AI is still an idea and has not yet been realized. To develop general AI, it will take machines that can process information, learn, and adapt to new tasks independently, without any human input.
Superintelligence is developing systems that exceed human capability in every way. Superintelligence is more of an idealistic or futuristic concept, however it does raise many ethical and existential concerns.
Understanding both concepts is important because they help to identify what we know about the current state of AI and where AI may eventually go.
Key Concepts in AI: Machine Learning, Deep Learning, and Neural Networks
The core of Artificial Intelligence is machine learning (AI). Machine learning is the method of training machines to draw conclusions from large amounts of data. A machine learning model learns from examples of data, and as it receives additional data, its decision-making capabilities improve over time without needing to be pre-programmed.
Deep Learning is one type of machine learning (ML). Deep Learning is based on neural networks with multiple layers that identify and understand complex patterns of information. Deep Learning enables the development and use of applications that can recognize images, understand natural language, and perform many other types of complex pattern recognition.
A neural network is an artificial system modeled after the human brain. Neural Networks are composed of nodes, or “neurons,” that are connected to one another. When nodes are connected, the network can learn and make decisions based on adjustments to the weights of its nodes.
A variety of methods exist for training neural networks, including:
1. Unsupervised Learning: finding patterns in unlabeled data sets.
2. Supervised Learning: learning from labelled data.
3. Reinforcement Learning: learning by trial and error.
In order to use some of the more advanced forms of Artificial Intelligence (AI), you will need to understand at least one form of learning. In addition to providing an introduction to learning techniques, this topic shows that while AI has significant potential for growth and development, it also poses challenges in its implementation and use.
