One of the hottest buzzwords in technology right now is artificial intelligence (AI), and for good reason. Many inventions and developments that were previously only found in science fiction have begun to materialize during the past several years.

Artificial intelligence is viewed by experts as a factor of production that has the ability to open up new avenues for growth and transform how work is carried out across industries. For instance, according to this PWC report, AI might by 2035 help the world economy grow by $15.7 trillion. With approximately 70% of the worldwide effect, China and the United States stand to gain the most from the upcoming AI boom.

This PrajnaWorld's tutorial provides an overview of AI, including how it works, its pros and cons, its applications, certifications, and why it’s a good field to master.

What Is Artificial Intelligence?

Artificial Intelligence is a method of making a computer, a computer-controlled robot, or a software think intelligently like the human mind. AI is accomplished by studying the patterns of the human brain and by analyzing the cognitive process. The outcome of these studies develops intelligent software and systems.

A Brief History of Artificial Intelligence

Artificial intelligence (AI) is a rapidly growing field that has been in development for several decades. Here is a brief history of artificial intelligence:

1950s: The field of AI began with the work of computer scientists like John McCarthy, Marvin Minsky, and Claude Shannon. They explored the possibility of creating machines that could reason, learn, and solve problems like humans.

1960s-70s: AI research experienced significant progress during this period, with the development of expert systems, natural language processing, and rule-based reasoning systems. These systems could perform specific tasks, but they were limited in their capabilities.

1980s-90s: This period saw a shift in AI research from rule-based systems to machine learning and neural networks. Researchers focused on developing algorithms that could learn from data and improve their performance over time.

2000s-present: Advances in machine learning, deep learning, and natural language processing have led to the development of sophisticated AI systems that can perform tasks like image and speech recognition, autonomous driving, and game playing. AI has also become increasingly integrated into everyday life, with applications in healthcare, finance, education, and other industries.

Today, AI is a rapidly evolving field that continues to push the boundaries of what machines can do. As AI technologies become more sophisticated and accessible, they have the potential to transform many aspects of our lives and society as a whole.

Types of Artificial Intelligence 

There are different ways to categorize artificial intelligence, but one common way is to classify it into the following types:

  • Reactive Machines: Reactive machines are the simplest type of AI system, which can only react to specific situations. They do not have the ability to learn or store information from previous experiences. Examples of reactive machines include chess-playing computers and voice assistants.
  • Limited Memory: Limited memory AI systems have the ability to store information from previous experiences and use that information to make decisions. Self-driving cars are an example of limited memory AI systems that use sensors to gather information about their surroundings and make decisions based on that information.
  • Theory of Mind: Theory of mind AI systems have the ability to understand the mental states of others, including their beliefs, intentions, and emotions. This type of AI is still in its early stages of development and is mostly used in research.
  • Self-Aware: Self-aware AI systems have the ability to understand their own existence and capabilities. This type of AI is still hypothetical and not yet developed.
  • Artificial General Intelligence (AGI): AGI refers to an AI system that has the same intelligence level as a human being. It would have the ability to learn and understand any intellectual task that a human can do. AGI is still hypothetical, and researchers are working to develop systems that can achieve this level of intelligence.
  • Artificial Superintelligence (ASI): ASI refers to an AI system that has intelligence beyond human-level intelligence. This type of AI is still purely theoretical and is the subject of ongoing research and debate in the field of AI.

These categories are not rigid and can overlap. Moreover, the development of AI is still an ongoing process, and new types of AI may emerge in the future as researchers make more advancements in the field.

How Does Artificial Intelligence Work?

Artificial intelligence (AI) works by using algorithms and data to enable machines to simulate human-like behavior, including learning, decision-making, and problem-solving. Here is a brief overview of how AI works:

  1. Data Collection: The first step in developing an AI system is to gather relevant data. This data can come from various sources, including sensors, databases, and user interactions.
  2. Data Preprocessing: Once the data is collected, it needs to be preprocessed to remove any noise, inconsistencies, or errors. This involves cleaning the data, transforming it into a usable format, and preparing it for analysis.
  3. Algorithm Development: The next step is to develop the algorithms that will enable the AI system to learn and make decisions. This involves selecting the appropriate machine learning or deep learning algorithms based on the task at hand.
  4. Training the Model: The AI system is then trained using the preprocessed data and the selected algorithms. During the training phase, the system learns to recognize patterns in the data and adjust its behavior accordingly.
  5. Model Evaluation: Once the AI system is trained, it needs to be evaluated to ensure that it is performing as expected. This involves testing the system on new data and comparing its performance to that of human experts.
  6. Deployment and Monitoring: Once the AI system is evaluated and deemed to be successful, it can be deployed into the real world. The system must be monitored and updated over time to ensure that it continues to perform well and adapts to changing conditions.

Overall, AI works by using data and algorithms to enable machines to simulate human-like behavior, learn from experience, and make decisions. The success of an AI system depends on the quality of the data, the effectiveness of the algorithms, and the ability of the system to adapt to changing conditions over time.

Ways of Implementing AI

There are several ways of implementing AI, depending on the specific task or problem that needs to be solved. Here are some common approaches:

  • Rule-based systems: This approach involves creating a set of rules that govern how an AI system should behave. These rules are typically based on expert knowledge or experience and are used to make decisions or take actions based on input data.
  • Machine learning: This approach involves training an AI system to learn from data. Machine learning algorithms are fed large amounts of data, and they use this data to identify patterns and make predictions or decisions based on new input data.
  • Deep learning: This is a subset of machine learning that involves training artificial neural networks to learn from data. Deep learning algorithms are capable of processing large amounts of complex data, such as images, speech, and natural language, and they can learn to recognize patterns and make decisions based on this data.
  • Evolutionary algorithms: This approach involves using techniques inspired by biological evolution to optimize AI systems. Evolutionary algorithms use a process of natural selection to evolve solutions to complex problems, such as optimizing the design of a machine or developing a trading strategy.
  • Natural language processing: This approach involves teaching AI systems to understand and process human language. Natural language processing is used to build chatbots, virtual assistants, and other applications that interact with humans using natural language.
  • Robotics: AI can also be implemented in robots to enable them to perform complex tasks, such as navigating a room or interacting with humans. Robotics combines several AI techniques, such as computer vision, machine learning, and natural language processing, to create intelligent machines.

These are just a few examples of the many ways AI can be implemented. The choice of approach depends on the specific problem to be solved and the available resources and expertise.

AI Programming Cognitive Skills: Learning, Reasoning and Self-Correction

Three cognitive abilities—learning, thinking, and self-correction—that the human brain possesses to varying degrees are the focus of artificial intelligence. In the context of AI, we define them as follows:

Learning is the process of gathering knowledge and developing the skills necessary to utilise it.

Reasoning: Using the principles of information to arrive at precise or approximative conclusions.

Self-Correction: The practice of continuously improving AI algorithms to make sure they provide the most precise results possible.

The objectives of AI, however, have been expanded and deepened to include the following:

  • Logical Analysis

AI software enables computers to carry out complex tasks. On February 10, 1996, Garry Kasparov was defeated by IBM's Deep Blue chess machine in a match.

  • Knowledge Representation

A reflective, dynamically typed, object-oriented programming language called Smalltalk was developed to support the "new world" of computers, which is typified by "human-computer symbiosis."

  • Planning and Direction

a method used to make it possible for computers to travel from point A to point B. Google's self-driving Toyota Prius is a great illustration of this.

  • Automatic Language Recognition

Install linguistically intelligent computers.

  • Perception

Use computers to communicate with the outside world via sight, sound, touch, and scent.

  • Emergent intelligence is intelligence that develops naturally from the other specialized AI qualities rather than being expressly coded. This objective envisions the development of machines with emotional intelligence and moral thinking.

The following are some of the jobs carried out by AI-enabled devices:

  • Speech synthesis
  • Detecting objects
  • Resolve issues and gain knowledge from the provided data
  • Prepare a strategy for conducting upcoming examinations.
