What is AI?

Artificial Intelligence (AI) are computer systems shaped to carry out tasks that demand human thought power. These systems work by looking at data, spotting patterns within data collections, and then making choices based on those spotted patterns. ‍

In other words, the systems are built to handle things like understanding human language, figuring out what's in pictures, solving puzzles, and even guessing what might happen later on.

Moreover, this whole field is always changing, with researchers constantly working on building better models that can tackle more complex, real-world problems. 

Types of AI Technology and Models

The field of AI is made up of several special subfields, each adding to the overall workings of AI systems:

• Machine Learning (ML): This subfield gets down to developing algorithms that let AI technology systems learn from data. The systems look at data, notice repeating patterns, and change their working settings without direct programming for each possible situation. This change happens through repeated data processing and model improvement.
  
• Deep Learning: A part of machine learning, deep learning uses artificial neural networks. These networks are set up to look like the information-processing abilities of the human brain. Deep learning models are used for tasks that need the study of complex, high-amount data, like picture and speech recognition.
  
• Natural Language Processing (NLP): NLP focuses on the back-and-forth between computers and human language. AI systems that have NLP abilities can get, understand, and make human language. This AI technology lets one develop applications like chatbots, virtual assistants, and automatic translation tools.
  
• Computer Vision: This area of AI goes down to understanding visual data. AI systems look at images and videos to spot objects, faces, and movements. This ability is key for applications like self-driving cars and image recognition software.
  
• Reinforcement Learning: Reinforcement learning gets down to AI systems that learn by trying things out and making mistakes. The systems get feedback from their interactions with an environment and change their actions to get the most reward. This way is used in applications like robotics and game playing.
  
• Generative AI: Generative AI models are made to create new content, including text, images, and music. These models work by learning the underlying patterns and structures in training data and then making new data that fit those patterns.

Types of AI Systems

To understand what is AI, you need to first understand that AI technology deals with huge amounts of data through algorithms. Algorithms are sets of computer instructions made to do specific tasks. 

By spotting patterns and learning from past interactions, AI systems fine-tune their responses and change over time. These systems usually use big data collections and lots of computer power to pull out meaningful insights. After all, how else would they do it?

Key ways used in AI include:

• Supervised Learning: In supervised learning, AI systems are trained using labeled data. Labeled data is input data paired with matching output data. The system learns to make guesses based on these examples.
  
• Unsupervised Learning: Unsupervised learning gets down to AI systems that spot patterns and relationships in data without direct labels. The system finds built-in structures in the data.
  
• Semi-Supervised Learning: This way puts together parts of supervised and unsupervised learning. AI systems are trained using a mix of labeled and unlabeled data, which helps to make accuracy and efficiency better.
  
• Neural Networks: Neural networks are computer structures based on the human brain. They deal with information through connected layers of nodes, with each layer doing a specific job in the overall processing of the data.

Different Types of AI Based on Functionality 

AI systems are sorted based on their abilities and working features.

• Narrow AI (Weak AI): Narrow AI systems are made to do specific tasks. Examples include spam filtering, voice recognition, and recommendation algorithms. These systems work within a limited range.
  
• General AI (Strong AI): General AI points to a thought-up form of AI that would have human-level thinking abilities. This type of AI would be able to reason and solve problems across many areas.
  
• Super AI: Super AI is a thought-up level of AI that would go beyond human intelligence in all ways. This idea stays in the world of thought-up guessing.
  
• Reactive Machines: Reactive AI systems work only based on set inputs. These systems don't have the ability to learn from past experiences. An example is a chess-playing computer that works based on a set of rules.
  
• Limited Memory AI: Limited memory AI systems can learn from past data. These systems store and use old data to make their performance better. Self-driving cars, which use sensor data to move around, are an example of this type of AI.
  
• Theory of Mind AI: Theory of Mind AI is a growing area of research that deals with letting AI systems understand emotions and social interactions. This type of AI would be able to notice and react to human emotions.
  
• Self-Aware AI: Self-aware AI is a thought-up idea involving AI systems with awareness and self-knowing. This type of AI is now purely thought-up.
