Artificial Intelligence (AI) is an emerging technology that enables computers and machines to simulate human intelligence and problem-solving capabilities. It involves the development of algorithms and models that enable computers to perform tasks that would typically require human intelligence, such as learning, reasoning, problem-solving, perception, and decision-making.
Artificial Intelligence has become increasingly prevalent in various domains, including natural language processing, computer vision, robotics, and decision support systems. As AI technology advances, it holds the potential to revolutionise numerous industries and aspects of our daily lives, while also raising important ethical considerations regarding its responsible development and deployment.
What is Artificial Intelligence?
Artificial Intelligence refers to machines performing human-like tasks. Its main components are Machine Learning algorithms that train on data, Neural Networks that mimic the brain's structure, and Natural Language Processing that understands human language. AI systems work by taking inputs, processing them with algorithms, and providing intelligent outputs that mimic human cognition and reasoning abilities.

- Natural language processing (NLP): NLP is a branch of artificial intelligence that deals with enabling computers to understand, interpret, and generate human language.
- Example: Virtual assistants like Siri or Alexa that can understand and respond to voice commands.
- Computer vision: It is an artificial intelligence interdisciplinary field that allows computers to comprehend and interpret digital images or videos to represent the visual world.
- Example: Self-driving cars that can detect and recognize objects, pedestrians, and traffic signals.
- Neural networks: Neural networks are a type of machine learning model inspired by the human brain's neural connections.
- They consist of interconnected nodes or neurons that process input data, learn to recognize patterns and make decisions or predictions based on that learning.
- Example: Recommendation systems used by streaming platforms like Netflix to suggest movies and shows based on user preferences.
Types of Artificial Intelligence
- Based on capabilities:
- Narrow AI (Weak AI)
- Narrow AI is designed for specific tasks and operates within predefined boundaries.
- Examples: Virtual assistants, chess-playing programs, speech recognition, spam filters
- General AI (Strong AI)
- Super AI
- A future form of AI surpasses human intelligence significantly.
- Based on functionality:
- Reactive Machines
- These AI systems operate in the present moment, reacting to current data without memory or past experiences.
- Examples: IBM’s Deep Blue (chess-playing AI) and Google’s AlphaGo
- Limited Memory Machines
- Artificial Intelligence with limited memory can use past data to make decisions but does not have a full history of interactions.
- Examples: Self-driving cars, language translation software
- Theory of Mind AI
- This type aims to understand human emotions, beliefs, intentions and thought processes.
- This type of AI is still in its infancy.
- Self-Aware AI
- AI that has a sense of self-awareness and consciousness, similar to human consciousness.
- It is highly speculative and not yet achieved.
How does AI work?
- AI systems acquire data, preprocess it, and extract relevant features.
- Appropriate algorithms like machine learning, deep learning, or rules are selected and trained on the data to learn patterns.
- The trained models are evaluated, optimized, and deployed to make predictions or decisions based on new input data.
- Artificial Intelligence combines techniques like natural language processing, computer vision, and reasoning to mimic human-like intelligence.
- It continuously learns and improves through exposure to more data and feedback.
