How does AI Work? Defining Artificial Intelligence
AI, or Artificial Intelligence, refers to using computer systems to perform tasks that would typically require human intelligence. At its core, AI involves creating algorithms and models that can analyze data, identify patterns, and make decisions based on that analysis. This technology is designed to learn and adapt over time, enabling it to perform increasingly complex tasks more accurately and efficiently.
The ultimate goal of AI is to create machines that can think and reason like humans and perform tasks that are beyond the capability of humans alone. Strong and Weak AI are two categories of artificial intelligence based on their level of intelligence and ability to mimic human cognition. So, how do these types of AI work?
Strong AI
Strong AI is a hypothetical form of artificial intelligence that would possess a consciousness and general intelligence at a human-like level. It’s when machines can think, reason, and make decisions like humans. While this type of AI is still science fiction, researchers continue to explore ways to develop more sophisticated and intelligent machines. Examples of strong AI in popular culture include the sentient robots in the movie series Terminator and the android Data in Star Trek: The Next Generation.
Weak AI
Weak AI is the current form of artificial intelligence that can perform specific tasks that typically require human intelligence. These machines can only perform the tasks they were designed for and cannot think or reason beyond their programming. Examples of weak AI include virtual assistants like Siri, Alexa, and Google Assistant, which use natural language processing and machine learning algorithms to understand and respond to user queries. Other examples include self-driving cars, chatbots, and recommendation systems on e-commerce websites.
Types of AI
AI systems can be broadly categorized into four types based on their capabilities and complexity. The four types of AI are reactive machines, limited memory, theory of mind, and self-awareness.
Let’s dive deeper into these types of AI, their characteristics, and their examples.
1. Reactive Machines
A reactive machine is the most basic type of AI. These machines are designed to perceive and react to the world in front of them without being able to store memories or past experiences. Reactive machines can only complete limited and specialized duties. However, the benefits of a reactive machine are that it is reliable and trustworthy. The best examples of reactive machines are Deep Blue and Google’s AlphaGo.
Examples of Reactive Machines:
Deep Blue: Designed by IBM in the 1990s, Deep Blue was a chess-playing supercomputer that defeated international grandmaster Gary Kasparov in a game.
Google’s AlphaGo: AlphaGo is a machine-learning algorithm that can play the board game “Go” at a superhuman level. It uses a neural network to evaluate the current game developments, giving it an edge over Deep Blue in a more complex game.
2. Limited Memory
Limited memory AI is more complex than reactive machines. It has the ability to store previous data and predictions while gathering information and weighing potential decisions. Limited memory AI presents greater possibilities than reactive machines. It is created when a team continuously trains a model to analyze and utilize new data, or an AI environment is built so models can be automatically trained and renewed.
The steps to utilizing limited memory AI in machine learning are:
- Establish training data
- Create the machine learning model
- Ensure the model can make predictions
- Ensure the model can receive human or environmental feedback
- Store human and environmental feedback as data
- Reiterate the steps above as a cycle
3. Theory of Mind
The theory of mind is a concept based on the psychological premise of understanding that other living things have thoughts and emotions that affect the behavior of oneself. In terms of AI, this would mean that machines could comprehend how humans, animals, and other machines feel and make decisions through self-reflection and determination. They would then utilize that information to make decisions of their own.
Examples of Theory of Mind:
Currently, there are no examples of theory of mind in AI because we don’t yet have the technological and scientific capabilities necessary to reach this level of AI.
4. Self Awareness
Self-awareness in AI relies on researchers understanding the premise of consciousness and then learning how to replicate it to build it into machines. This type of AI possesses human-level consciousness and understands its own existence in the world and the presence and emotional state of others. It would be able to understand what others may need based on what they communicate to them and how they communicate it.
Examples of Self-Awareness:
There are no examples of self-aware AI because we have yet to achieve the technological and scientific capabilities necessary to reach this level of AI.

How Does AI Work and What is Under the Hood?
AI, or artificial intelligence, is the field of computer science that focuses on creating intelligent machines that can learn and perform tasks without being explicitly programmed. The development of AI has enabled computers to perform complex tasks that were previously only possible for humans. AI uses several methods to achieve its objectives, including machine learning, neural networks, natural language processing, and robotics. So, let’s dive deeper in the effort to answer the question: how does artificial intelligence work?
Machine Learning
Machine learning is a subset of AI that enables computers to learn and improve independently by analyzing and adapting to data. There are several machine learning techniques, but the three main ones are supervised, unsupervised, and reinforcement learning.
- Supervised Learning: Supervised learning involves training a model on labeled data, which means the data set includes inputs and the desired outputs. The algorithm learns from these labeled data points and can then predict new, unseen data. Examples of supervised learning include image classification, spam detection, and speech recognition.
- Unsupervised Learning: Unsupervised learning involves finding patterns in unlabeled data, which means the data set includes only inputs with no corresponding outputs. The algorithm looks for patterns and relationships in the data and uses these patterns to make predictions on new, unseen data. Examples of unsupervised learning include clustering, anomaly detection, and dimensionality reduction.
- Reinforcement Learning: Reinforcement learning involves training a model through trial and error by rewarding or punishing specific actions. The algorithm learns through interaction with an environment and receives rewards for correct actions and punishments for incorrect ones. Reinforcement learning is commonly used in robotics, gaming, and recommendation systems.
- Other types of machine learning: In addition to supervised, unsupervised, and reinforcement learning, other machine learning techniques are commonly used. These include semi-supervised learning, where the model learns from labeled and unlabeled data, and deep learning, which uses neural networks to learn from vast amounts of data. Transfer learning is another popular technique using a pre-trained model as a starting point for a new task.
Neural Networks
Neural networks are a subset of machine learning that utilizes a network of artificial neurons to process and analyze data. They are modeled after the structure and function of the human brain, allowing them to identify patterns and relationships within data sets.
Neural networks are a powerful tool in the field of AI, particularly in the area of machine learning.
Neural networks can be trained on large datasets and learn to make predictions and decisions based on that data. This makes them useful for various applications, including image and speech recognition, natural language processing, and game playing. The ability of neural networks to learn and improve over time through feedback makes them an essential component of many AI systems.
Natural Language Processing
Natural language processing (NLP) is a crucial component of AI that enables computers to process, analyze, and understand human language. NLP involves developing algorithms and models that can interpret and derive meaning from human speech or text, which allows machines to perform various tasks such as language translation, sentiment analysis, and chatbot interactions. By enabling machines to understand human language, NLP makes it possible to create more sophisticated and intuitive AI applications that interact with humans more naturally and effectively, enhancing the overall user experience.
