4 Functional Types of AI 

The categorization of AI is based on its interaction with the environment and information exchange.

1.  Reactive Machines:
   A reactive machine is the simplest form of AI out there. These are specifically designed to give a stipulated set of outputs for certain inputs, but they cannot remember nor learn from previous experiences.
   Example: IBM, Deep Blue chess-playing computer. The Deep Blue did not need to refer to the previous games in order to estimate real-time moves.
   Real-World Applications: These systems are applied in elementary automation tasks, for example, in filters where they sort through spam and simple chatbots. 
2. Limited Memory AI:
   Decision-making-based memory available in limited memory AI can be made for a limited time only, which has been stored in it. This type is typical for today’s uses of AI.  
   Example: Self-driving cars. They include aspects like using sensing devices to view the environment and capture information about objects in front of the vehicle and its vicinity.
   Real-World Applications: Applied to recommendation engines (like Netflix), dynamic pricing mechanisms, and fraud detection applications.  
3. Theory of Mind AI
   This type of AI directly wants to recognize and interpret emotions, beliefs, and intent to facilitate a social conversation. However, currently in the research phase, Theory of Mind AI has great potential. For instance, ongoing research projects aim to develop advanced AI capable of interpreting human emotions and social cues to enhance human-computer interaction.
   Example:Examples include experimental AI companions and virtual tutors designed to adapt to users’ emotional states. These advancements highlight the profound possibilities this AI type could unlock in healthcare, education, and beyond.
   Challenges: Establishing such states calls for improvements in cognitive models as well as emotional intelligence.  
4. Self-Aware AI
   The final achievement in artificial intelligence would mean an intelligent being, an artificial entity with consciousness and emotions, and the ability to know that it actually exists. Although not yet in existence, it is quite famous in science fiction movies.
   Example: In films like Ex Machina and Her, there are artificially intelligent machines that can think for themselves.  
   Ethical Implications: If an AI is capable of self-improvement, then there are issues of rights, responsibilities, and regulation at play.

Capability-Based Types of AI

AI is known to consist of functionality ranging from job automation to likely superintelligence. There are different types of AI.

1. Artificial Narrow Intelligence (ANI)  
   Weak AI or ANI is made for one purpose only. It still works only based on some inputs and cannot go beyond the commands which are installed in it.  
   Example: Some common application of ANI includes; chatbots, voice assistants, and spam filters. 
   Real-World Applications: An example of where ANI is used is in e-commerce recommendation, health care diagnosis, and in finance, anti-fraud controls.  
2. Artificial General Intelligence (AGI)  
   In the context of AGI, there is a term of a machine that is able to learn, and reason, and problem solve in one or more domain.  
   Example: In this case, AGI might be able to understand the scientific issues, do creative works, and work with new situations.  
   Current Status: AGI is still under study and development, some of the current projects are OpenAI.  
3. Artificial Super Intelligence (ASI)
   ASI stands for Artificial Super Intelligence where AI systems are far superior than human beings in every way. These systems could provide for the capability of innovation as well as solve various global problems on their own.  
   Example: ASI is a concept in theory but the possible future application areas range from climate modeling, global health smart systems and even space probes.  
   Risks: The major challenge will be to ensure that what is being implemented and promoted in ASI complies with the best human vales and ethical standards. 

Types of AI Tools

Different types of AI tools are used in artificial intelligence products. It supports the process of automation as well as facilitating the decision-making process and increasing creativity.
