The rules are typically expressed in the form of “if-then” statements, where specific conditions lead to prescribed actions or outcomes.

Key Components of Rule-Based Systems:

  1. Knowledge Base:

    • Contains a set of rules or knowledge representations that define the system’s behavior.
    • Rules are typically organized in a hierarchical or modular structure.

  2. Inference Engine:

    • Responsible for processing the rules and making inferences or decisions.
    • Evaluates input data against the rules to derive conclusions.

  3. Working Memory:

    • Stores the current state of the system and the data being processed.
    • Updated as the inference engine makes decisions.

  4. Rule Interpreter:

    • Translates and executes the rules specified in the knowledge base.
    • Drives the reasoning process based on input data.

Example Rule-Based System:

Consider a simple rule-based system for traffic light control:

vbnet
Rule 1: If time_of_day is "morning" and traffic_density is "low", then set_traffic_light to "green".
Rule 2: If time_of_day is "afternoon" and traffic_density is "moderate", then set_traffic_light to "yellow".
Rule 3: If time_of_day is "evening" or traffic_density is "high", then set_traffic_light to "red".

Knowledge engineering

Knowledge Engineering is the process of acquiring, representing, and incorporating knowledge into a computer system. It involves capturing human expertise, domain knowledge, and problem-solving heuristics in a form that can be used by AI systems, including rule-based systems. The goal is to create a knowledge base that enables the system to make intelligent decisions or solve problems within a specific domain.

Steps in Knowledge Engineering:

  1. Knowledge Acquisition:

    • Gathering information and expertise from domain experts.
    • Interviews, surveys, and documentation reviews are common methods.

  2. Knowledge Representation:

    • Structuring acquired knowledge in a format suitable for computer processing.
    • In rule-based systems, this often involves creating rules and organizing them hierarchically.

  3. Knowledge Validation:

    • Ensuring that the acquired knowledge is accurate, consistent, and relevant to the problem domain.
    • Involves feedback from domain experts and validation against real-world scenarios.

  4. Knowledge Integration:

    • Incorporating the structured knowledge into the AI system.
    • Integrating rules into the knowledge base for use by the inference engine.

Inference engines

Inference Engines are components of AI systems, especially rule-based systems, responsible for drawing conclusions or making decisions based on the rules and input data. The inference engine processes the rules in the knowledge base and determines the appropriate actions or outcomes.

Key Functions of Inference Engines:

  1. Pattern Matching:

    • Matching input data against the conditions specified in the rules.
    • Identifying rules whose conditions are satisfied.

  2. Rule Execution:

    • Applying the actions specified in rules whose conditions are satisfied.
    • Executing the “then” part of the matched rules.

  3. Conflict Resolution:

    • Handling situations where multiple rules are applicable.
    • Prioritizing and resolving conflicts based on predefined criteria.

  4. Inference Strategies:

    • Determining how to use the rules to make decisions.
    • Common strategies include forward chaining (data-driven) and backward chaining (goal-driven).

Inference engines play a crucial role in the decision-making process of rule-based systems, enabling them to derive conclusions from input data and apply logical reasoning to solve problems.

Artificial Intelligence Tutorial for Beginners in 2024 | Learn AI Tutorial from Experts

The Artificial Intelligence tutorial provides an introduction to AI which will help you to understand the concepts behind Artificial Intelligence. In this tutorial, we have also discussed various popular topics such as History of AI, applications of AI, deep learning, machine learning, natural language processing, Reinforcement learning, Q-learning, Intelligent agents, Various search algorithms, etc.

Our AI tutorial is prepared from an elementary level so you can easily understand the complete tutorial from basic concepts to the high-level concepts

What is Artificial Intelligence (AI)?

The answer to this question would depend on who you ask. A layman, with a fleeting understanding of technology, would link it to robots. If you ask about artificial intelligence to an AI researcher, (s)he would say that it’s a set of algorithms that can produce results without having to be explicitly instructed to do so. Both of these answers are right. So to summarize, Artificial Intelligence is:

  1. An intelligent entity created by humans.
  2. Capable of performing tasks intelligently without being explicitly instructed.
  3. Capable of thinking and acting rationally and humanely.

At the core of Artificial Intelligence, it is a branch of computer science that aims to create or replicate human intelligence in machines. But what makes a machine intelligent? Many AI systems are powered with the help of machine learning and deep learning algorithms. AI is constantly evolving, what was considered to be part of AI in the past may now just be looked at as a computer function. For example, a calculator may have been considered to be a part of AI in the past. Now, it is considered to be a simple function. Similarly, there are various levels of AI, let us understand those.

Why is Artificial Intelligence Important?

The goal of Artificial Intelligence is to aid human capabilities and help us make advanced decisions with far-reaching consequences. From a technical standpoint, that is the main goal of AI. When we look at the importance of AI from a more philosophical perspective, we can say that it has the potential to help humans live more meaningful lives that are devoid of hard labour. AI can also help manage the complex web of interconnected individuals, companies, states and nations to function in a manner that’s beneficial to all of humanity.

Currently, Artificial Intelligence is shared by all the different tools and techniques have been invented by us over the last thousand years – to simplify human effort, and to help us make better decisions. Artificial Intelligence is one such creation that will help us in further inventing ground-breaking tools and services that would exponentially change how we lead our lives, by hopefully removing strife, inequality and human suffering.

We are still a long way from those kinds of outcomes. But it may come around in the future. Artificial Intelligence is currently being used mostly by companies to improve their process efficiencies, automate resource-heavy tasks, and to make business predictions based on data available to us. As you see, AI is significant to us in several ways. It is creating new opportunities in the world, helping us improve our productivity, and so much more. 

History of Artificial Intelligence

The concept of intelligent beings has been around for a long time and have now found its way into many sectors such as AI in education, automotive, banking and finance, AI healthcare etc. The ancient Greeks had myths about robots as the Chinese and Egyptian engineers built automatons. However, the beginnings of modern AI has been traced back to the time where classical philosophers’ attempted to describe human thinking as a symbolic system. Between the 1940s and 50s, a handful of scientists from various fields discussed the possibility of creating an artificial brain. This led to the rise of the field of AI research – which was founded as an academic discipline in 1956 – at a conference at Dartmouth College, in Hanover, New Hampshire. The word was coined by John McCarthy, who is now considered as the father of Artificial Intelligence.

Despite a well-funded global effort over numerous decades, scientists found it extremely difficult to create intelligence in machines. Between the mid-1970s and 1990s, scientists had to deal with an acute shortage of funding for AI research. These years came to be known as the ‘AI Winters’. However, by the late 1990, American corporations once again were interested in AI. Furthermore, the Japanese government too, came up with plans to develop a fifth-generation computer for the advancement of AI. Finally, In 1997, IBM’s Deep Blue defeated the first computer to beat a world chess champion, Garry Kasparov.

As AI and its technology continued to march – largely due to improvements in computer hardware, corporations and governments too began to successfully use its methods in other narrow domains. The last 15 years, Amazon, Google, Baidu, and many others, have managed to leverage AI technology to a huge commercial advantage. AI, today, is embedded in many of the online services we use. As a result, the technology has managed to not only play a role in every sector, but also drive a large part of the stock market too. 

Today, Artificial Intelligence is divided into sub-domains namely Artificial General Intelligence, Artificial Narrow Intelligence, and Artificial Super Intelligence which we will discuss in detail in this article. We will also discuss the difference between AI and AGI.

Levels of Artificial Intelligence

Artificial Intelligence can be divided into three main levels:

  1. Artificial Narrow Intelligence
  2. Artificial General Intelligence
  3. Artificial Super-intelligence

Artificial Narrow Intelligence (ANI)

Also known as narrow AI or weak AI, Artificial narrow intelligence is goal-oriented and is designed to perform singular tasks. Although these machines are seen to be intelligent, they function under minimal limitations, and thus, are referred to as weak AI. It does not mimic human intelligence; it stimulates human behaviour based on certain parameters. Narrow AI makes use of NLP or natural language processing to perform tasks. This is evident in technologies such as chatbots and speech recognition systems such as Siri. Making use of deep learning allows you to personalise user experience, such as virtual assistants who store your data to make your future experience better. 

Examples of weak or narrow AI:

  1. Siri, Alexa, Cortana
  2. IBMs Watson
  3. Self-driving cars
  4. Facial recognition softwares
  5. Email spam filters 
  6. Prediction tools 

Artificial General Intelligence (AGI)

Also known as strong AI or deep AI, artificial general intelligence refers to the concept through which machines can mimic human intelligence while showcasing the ability to apply their intelligence to solve problems. Scientists have not been able to achieve this level of intelligence yet. Significant research needs to be done before this level of intelligence can be achieved. Scientists would have to find a way through which machines can become conscious through programming a set of cognitive abilities. A few properties of deep AI are-

  1. Recognition
  2. Recall 
  3. Hypothesis testing 
  4. Imagination
  5. Analogy
  6. Implication

It is difficult to predict whether strong AI will continue to advance or not in the foreseeable future, but with speech and facial recognition continuously showing advancements, there is a slight possibility that we can expect growth in this level of AI too. 

Artificial Super-intelligence (ASI)

Currently, super-intelligence is just a hypothetical concept. People assume that it may be possible to develop such an artificial intelligence in the future, but it doesn’t exist in the current world. Super-intelligence can be known as that level wherein the machine surpasses human capabilities and becomes self-aware. This concept has been the muse to several films, and science fiction novels wherein robots who are capable of developing their feelings and emotions can overrun humanity itself. It would be able to build emotions of its own, and hypothetically, be better than humans at art, sports, math, science, and more. The decision-making ability of a super-intelligence would be greater than that of a human being. The concept of artificial super-intelligence is still unknown to us, its consequences can’t be guessed, and its impact cannot be measured just yet. 

Weak AIStrong AI
1. It is a narrow application with a limited scope.1. It is a wider application with a more vast scope.
2. This application is good at specific tasks.2. This application has an incredible human-level intelligence.
3. It uses supervised and unsupervised learning to process data.          3. It uses clustering and association to process data.
Example: Siri, Alexa.Example: Advanced Robotics

Applications of Artificial Intelligence

Artificial intelligence has paved its way into several industries and areas today. From gaming to healthcare, the application of AI has increased immensely. Did you know that the Google Maps applications and facial recognition such as on the iPhone are all using AI technology to function? AI is all around us and is part of our daily lives more than we know it. Here are a few applications of Artificial Intelligence.

Best Applications of Artificial Intelligence in 2024

  1. Google’s AI-powered predictions (Google Maps)
  2. Ride-sharing applications (Uber, Lyft)
  3. AI Autopilot in Commercial Flights
  4. Spam filters on Emails
  5. Plagiarism checkers and tools
  6. Facial Recognition
  7. Search recommendations
  8. Voice-to-text features
  9. Smart personal assistants (Siri, Alexa)
  10. Fraud protection and prevention

Now that we know these are the areas where AI is applied. Let us understand these in a more detailed way. Google has partnered with DeepMind to improve the accuracy of traffic predictions. With the help of historical traffic data as well as the live data, they can make accurate predictions through AI technology and machine learning algorithms. An intelligent personal assistant can perform tasks based on commands given by us. It is a software agent and can perform tasks such as sending messages, performing a google search, recording a voice note, chatbots, and more. 

Goals of Artificial Intelligence

So far, you’ve seen what AI means, the different levels of AI, and its applications. But what are the goals of AI? What is the result that we aim to achieve through AI? The overall goal would be to allow machines and computers to learn and function intelligently. Some of the other goals of AI are as follows:

1. Problem-solving: Researchers developed algorithms that were able to imitate the step-by-step process that humans use while solving a puzzle. In the late 1980s and 1990s, research had reached a stage wherein methods had been developed to deal with incomplete or uncertain information. But for difficult problems, there is a need for enormous computational resources and memory power. Thus, the search for efficient problem-solving algorithms is one of the goals of artificial intelligence.

2. Knowledge representation: Machines are expected to solve problems that require extensive knowledge. Thus, knowledge representation is central to AI. Artificial intelligence represents objects, properties, events, cause and effect, and much more. 

3. Planning: One of the goals of AI should be to set intelligent goals and achieve them. Being able to make predictions about how actions will impact change, and what are the choices available. An AI agent will need to assess its environment and accordingly make predictions. This is why planning is important and can be considered as a goal of AI. 

4. Learning: One of the fundamental concepts of AI, machine learning, is the study of computer algorithms that continue to improve over time through experience. There are different types of ML. The commonly known types of are Unsupervised Machine Learning and Supervised Machine Learning. 

5. Social Intelligence: Affective computing is essentially the study of systems that can interpret, recognize, and process human efforts. It is a confluence of computer science, psychology, and cognitive science. Social intelligence is another goal of AI as it is important to understand these fields before building algorithms. 

Thus, the overall goal of AI is to create technologies that can incorporate the above goals and create an intelligent machine that can help us work efficiently, make decisions faster, and improve security. 

Jobs in Artificial Intelligence

The demand for AI skills has more than doubled over the last three years, according to Indeed. Job postings in the field of AI have gone up by 119%. The task of training an image-processing algorithm can be done within minutes today, while a few years ago, the task would take hours to complete. When we compare the skilled professionals in the market with the number of job openings available today, we can see a shortage of skilled professionals in the field of artificial intelligence.

Bayesian Networking, Neural nets, computer science (including knowledge about programming languages), physics, robotics, calculus and statistical concepts are a few skills that one must know before deep diving into a career in AI. If you are someone who is looking to build a career in AI, you should be aware of the various job roles available.
