When you think about Artificial Intelligence, Chat-GPT or Alexa probably comes to mind, but AI can be much more than that. From simple if-else AIs, to AI’s that can understand emotions, there’s not just one singular type of AI that classifies them all. There are four different types of AI, and all four will be covered in this article.
Types Of Artificial Intelligence
Reactive: Reactive AI refers to a type of artificial intelligence that can only respond to the immediate situation based on predefined rules and input. It doesn’t have memory or the ability to learn from past experiences. It simply reacts to current stimuli. This type of AI is typically seen in basic game AI or simple automation tasks. For example this type of AI can be compared to an if-else statement. If button clicked, then function(submit).
Limited memory: Limited memory AI, also known as ‘memory-bounded’ AI, is an artificial intelligence system that has the ability to store and recall past experiences or data, but only within certain limitations. It can use this stored information to make decisions or predictions, but it doesn’t have an unlimited capacity for memory or the ability to learn from vast amounts of data like other AI models. This is the level of AI base Chat-GPT 4 is on. It has access to large amount of data, and it can recall past messages in the specific chat the instance is in, but it cannot remember the same things if outside the specific chat.
Theory of mind: Theory of mind in AI refers to the ability of a system to understand and attribute mental states such as beliefs, desires, intentions, or emotions to others. This capability allows the AI to anticipate and model the behavior of other agents in a social context. It’s an essential aspect for creating more human-like interactions between AI and humans or between AI agents. It’s getting scary. This AI can understand emotions, but not exactly replicate them as their own. Believe it or not, theory of mind has been developed.
Self-aware: Self-aware AI, sometimes referred to as ‘conscious AI’, is a hypothetical type of artificial intelligence that has a level of awareness and understanding of its own existence, internal states, and capabilities. It would possess a sense of identity and be able to reflect on itself. Self-aware AI (thankfully) doesn’t exist yet, but it might be coming very soon.
Artificial Intelligence doesn’t only include AIs like Chat-GPT. There are many types of AI that you probably use every day without knowing. YouTube algorithm is a type of Limited memory AI. By using your past watched videos, liked videos, and engagement time, it can conjure up a set of recommended videos for you to watch. Even the most simple things, like charging your phones have become incorporated with AI. iPhones use a Limited memory AI that monitors when you usually wake up, to finish charging right around the time when you pick up your phone to go to school or work. (This increases battery longevity as keeping a battery at 100% for long periods of time is damaging to the battery.)
As Artificial Intelligences keep growing more and more advanced AIs are becoming incorporated into our daily lives. Smart lights, smart fridges, mesh wifi, or even an (actually good) AI that’s built into your computer or smartphone will be a thing of the future. AI is everywhere and it is impossible to escape it.
