What is Artificial Intelligence (AI)?

Artificial intelligence (AI) is the development, deployment, and maintenance of computational systems that can replicate certain types of human intelligence. Currently, this aspect of computer science is focused on creating algorithms and programming machine learning (ML) models that can analyze vast amounts of data to gain insights and make data-driven decisions autonomously.


Essentially, artificial intelligence initiatives combine elements of mathematics and computational neuroscience to simulate and/or enhance human thought processes. An important goal of this research field is to investigate how technology can be used to carry out cognitive tasks that humans find tedious or challenging.

AI is considered to be a disruptive technology because it is changing the way people access and process information, do their jobs, and understand the nature of creativity and originality.

Techopedia Explains the AI Meaning

Artificial Intelligence (AI)

Most AI definitions explain the positive aspects of using artificial intelligence to enhance human intelligence and help people be more productive.

It should be noted, however, that critics of the technology have expressed concerns that increasingly powerful AI models could soon surpass human intelligence and eventually become a threat to humanity.

The uncontrolled advancement of AI and the technology’s potential to accelerate beyond human control is sometimes referred to as The Singularity. The theoretical potential for The Singularity to become real is just one reason why governments, industry segments, and large corporations are putting AI guardrails in place to minimize risk and ensure that artificial intelligence is used responsibly.

How Artificial Intelligence Works

Today, AI applications typically use advanced machine learning algorithms and vast amounts of computational power to process, analyze, and learn from data in ways that mimic specific aspects of human cognition, like pattern recognition and inductive reasoning.

The first step when developing an AI model that uses ML involves data acquisition. The specific data type will be determined by the AI’s intended function. For example, an image recognition model will require a massive dataset of digital images.

Once the data has been collected, data scientists can select or develop algorithms to analyze the data. The algorithms – which are essentially sets of instructions – are sets of instructions that tell the computer how to process data and arrive at an output.

Many machine learning algorithms, including deep learning algorithms, are designed to be used iteratively. They get exposed to data, make predictions/decisions, and then receive feedback to adjust their internal processes. The process of allowing algorithms to improve their outputs over time is referred to as machine learning (ML).

The learning process can be supervised or unsupervised, depending on how the data is presented and what the AI programming is meant to achieve.

With supervised learning, the AI model learns from a dataset that includes both the input and the desired output.  With unsupervised learning, the algorithm identifies patterns, relationships, or structures in the data it receives and then uses the analysis to predict outputs.

Once an AI model can reliably predict outputs for unseen training data with an acceptable range of accuracy, it can be tested with real-world data. At this point, the model will either be retrained or deployed and monitored continuously for model drift.

H3: The Difference between Machine Learning and AI

While AI and ML are often used as synonyms, the artificial intelligence meaning is an umbrella term, and machine learning is a subset of artificial intelligence. Essentially, every ML application can be referred to as AI, but not all artificial intelligence applications use machine learning. For example, rule-based symbolic AI falls under the AI umbrella, but it isn’t a true example of machine learning because it doesn’t learn from data the way ML does.

Examples of AI Technology

Today’s AI often uses machine learning in conjunction with other computational techniques and technologies. A hybrid approach allows for more nuanced and robust AI systems.

For example, deep learning is an iterative approach to artificial intelligence that stacks machine learning algorithms in a hierarchy of increasing complexity and abstraction. It is currently the most sophisticated AI architecture in use.

Other well-known AI techniques and technologies include:

Generative AI
Uses deep learning techniques to analyze huge datasets of text, code, or multimedia content – and then uses predictive modeling to create entirely original, yet stylistically consistent, outputs.

Neural Networks
Inspired by the human brain, neural networks consist of interconnected nodes called artificial neurons. The neurons work in layers to process data, identify patterns, and make decisions. Each layer transforms the input data, using weights to produce an output. Variants like convolutional neural networks (CNNs) and recurrent neural networks (RNNs) are tailored for specific tasks like image recognition and sequential data analysis, respectively.

General Adversarial Networks
Two AI models play a “game” that requires one model to generate realistic data and the other to decide if the data is real or fake. The game continues until the second model can no longer tell if the data is real or if it’s deepfake.   
AI technologies in robotics enable physical robots to perform tasks autonomously or semi-autonomously. They include medical robots that can perform operations, industrial robots for manufacturing, delivery, and surveillance drones, and robotic assistants that can help with housework.
Natural Language Processing (NLP) and Natural Language Understanding (NLU)
 NLP and NLU technologies allow machines to read, understand, and interpret human language. These technologies are used with machine learning to enable speech-to-text applications, language translation applications like Google Cloud Translation, and text analysis for conversational agents that use generative AI. NLP provides the tools for processing language, while NLU focuses on deriving meaning from that processed data.
Computer Vision
Computer vision technology enables machines to interpret and make decisions based on visual data. Applications range from facial recognition systems and medical image analysis to enabling real-time analysis for physical security feeds.
Facial Recognition
Analyzes and compares patterns in facial features from images or video feeds to identify or verify the identity of a specific individual.
Speech Recognition
Turns spoken words into text by analyzing sound waves, identifying patterns, and matching them to patterns learned from training data
Voice Recognition
Expert Systems
Expert systems are computer programs that mimic human experts in a specific field. They rely on pre-programmed knowledge and rules to solve problems.

Types of Artificial Intelligence

Artificial intelligence can be categorized as being either weak AI or strong AI. All artificial intelligence in use today is considered to be weak AI.

Weak AI

Weak AI, also known as narrow AI, is capable of performing a limited number of predetermined functions.

Even powerful multimodal AI chatbots like Google Gemini and ChatGPT are still a type of weak AI. These two families of large language models (LLMs) had to be programmed how to respond to user prompts, and they will require more programming if they are going to be used for new tasks.

Strong AI

Strong AI doesn’t exist yet, but researchers and AI advocates have expressed interest in two distinct types of strong AI: artificial general intelligence (AGI) and artificial superintelligence.

Artificial general intelligence is a hypothetical type of AI that possesses human-level intelligence. In theory, AGI will be able to learn, reason, and solve problems in an interdisciplinary manner across all domains. The technology will be able to respond autonomously to new types of outside stimuli without explicit programming.

Superintelligence is the type of hypothetical AI that is often depicted in science fiction books. This type of AI will far surpass AGI capabilities and be more intelligent than human beings.

It’s important to note that no AGI or superintelligent systems have been developed yet, and there is still considerable debate among experts about when – or even if – they will be achieved. The negative and positive implications of superintelligence are the subject of much debate within the AI community and society at large.

AI models can also be categorized by their decision-making capabilities and levels of cognitive sophistication.

Reactive AI
Reactive AI models are a type of weak AI that relies on real-time data to make decisions. Model outputs are solely based on inputs from the current session. IBM’s Deep Blue, which defeated chess champion Garry Kasparov before the turn of the century, is an example of reactive AI. The programming could evaluate possible moves and their outcomes in the current session, but it did not know anything about past games.

Limited Memory AI
Limited Memory AI is a type of weak AI that relies on stored data to make decisions. Email spam filters use limited memory AI. First the programming uses supervised learning to analyze a huge number of email messages that have been previously identified as spam. Then it uses this knowledge to identify and filter out new emails that exhibit similar characteristics.

Theory of Mind AI
Theory of Mind AI, like artificial general intelligence, is a hypothetical type of strong AI. Essentially, this type of AI will be able to consider subjective elements such as user intent when making decisions.
Self-Aware AI
Self-aware AI is another type of hypothetical strong AI. Self-aware AI models will have their own consciousness, emotions, and self-awareness.

AI Use Cases in Business

Artificial intelligence technology is streamlining business operations and increasing efficiency across various business sectors, but it is also requiring employees to upskill and adapt to new roles and responsibilities within the workplace.

As routine tasks become automated, the workforce is expected to shift towards more analytical, creative, and supervisory roles that AI technology cannot fulfill. The hope is that the transition will not only enhance employee productivity, it will also allow employees to focus on strategic and creative tasks that add greater value to the business.

The ability of AI to analyze vast amounts of data in real time is enabling businesses to tailor their offerings to specific customer segments and identify opportunities for growth and improvement more effectively than ever before. The integration of AI in business operations is also transforming marketing engagement strategies. Personalized recommendations and chatbots that provide interactive customer service 24/7 are allowing companies to offer unprecedented levels of customer support.

Benefits and Risks of Artificial Intelligence

As AI becomes a standard technology for business applications, there is growing concern about its ethical use, benefits, and risks.

The ethical use of AI calls for careful consideration and management of these risks to ensure that the technology is used in a way that is beneficial to society and does not exacerbate inequalities or harm individuals or groups.

Artificial intelligence has also introduced complex legal considerations that businesses must navigate carefully. These concerns include issues related to data privacy, AI bias and the impact of AI on employment, as well as its impact on society.

Determining who is responsible when AI systems make harmful decisions can be challenging, especially for complex AI systems whose outputs have hundreds or even thousands of dependencies. For example, when an AI-powered self-driving car causes an accident, determining who is liable – the developer, the company, or the user – is a significant challenge. It’s even more complicated if the vehicle’s operation has been compromised by a malware attack.

It’s becoming increasingly clear that companies need to establish clear guidelines and best practices to ensure that employee use of AI-enhanced technology remains in compliance with corporate policies.

The table below provides a high-level view of AI’s dual-edged nature.


  • Efficiency & productivity gains
  • Enhanced problem-solving
  • Personalized experiences
  • Innovation & breakthroughs


  • Job displacement
  • Algorithmic bias
  • Privacy infringement
  • Lack of transparency & accountability

Regulatory Compliance and Artificial Intelligence

As AI applications become more integrated into critical sectors of e-commerce, agriculture, healthcare and finance, the need for sharing best practices and adopting standardized AI frameworks like NIST’s AI Risk Management Framework and Google SAIF has never been greater.

To reduce the economic and societal risks of developing and/or using AI, many countries around the world are creating new policies, laws, and regulations.

Here is a short list of some of the initiatives currently in play:

The first comprehensive regulatory framework to be approved by a government body. The legislation establishes clear rules for AI providers and users in accordance with the level of risk the artificial intelligence poses. It also requires content created with generative AI to comply with transparency requirements and EU copyright law.
