Chapter 4: AI and Its Types Class 6

🧭 Chapter Overview

Artificial Intelligence (AI) can be divided into different types based on how capable the AI system is and how it functions.
Understanding these types helps us know what AI can do today and what it might achieve in the future.

This chapter explains:

  • The two major ways of classifying AI
  • Examples of each type
  • How AI evolves from simple to super-intelligent systems

4.1 Introduction to AI Types

💡 Definition:

AI systems are grouped into types based on:

  1. Capabilities – How much the AI can learn and evolve.
  2. Functionality – How the AI works or performs tasks.

🧩 Why Classification Is Important:

ReasonDescription
Understanding GrowthShows how AI develops from simple to complex.
Technology LevelsHelps researchers build advanced systems.
Safety & ControlHelps identify what level of human supervision is needed.

4.3 AI Type–1: Based on Capabilities

This classification shows how capable or powerful an AI system is in terms of thinking, reasoning, and learning.

There are three main types 👇


1️⃣ Artificial Narrow Intelligence (ANI)

(Also known as Weak AI)

FeatureDescription
DefinitionAI designed to perform a single specific task.
AbilityWorks within a limited pre-defined range.
LearningCannot learn beyond what it’s programmed for.
ExampleAlexa, Siri, ChatGPT, Google Assistant, Chess AI.

🧩 Key Idea:
Narrow AI ≈ One skill, one goal.


2️⃣ Artificial General Intelligence (AGI)

(Also known as Strong AI)

FeatureDescription
DefinitionAI that can understand, learn, and apply knowledge like a human being.
AbilityCan perform multiple tasks and think independently.
StatusStill under research and development.
ExampleHypothetical — future human-like robots or Jarvis (Iron Man).

🧩 Key Idea:
AGI ≈ AI that thinks like a human.


3️⃣ Artificial Super Intelligence (ASI)

FeatureDescription
DefinitionAI that surpasses human intelligence and capabilities.
AbilityCan think, reason, and create beyond human imagination.
RiskMight become uncontrollable if not ethically developed.
ExampleCurrently non-existent — only theoretical (like Ultron).

🧩 Key Idea:
ASI ≈ AI smarter than all humans combined.

4.4 AI Type–2: Based on Functionality

This classification shows how AI behaves and functions — how it uses memory, learning, and awareness to make decisions.

There are four major types 👇


1️⃣ Reactive Machines

FeatureDescription
DefinitionBasic AI that reacts to current situations without memory.
AbilityNo learning from past data.
Decision MakingOnly responds based on programmed logic.
ExampleIBM’s Deep Blue (chess-playing computer).

🧩 Key Idea:
Reactive AI = “If this happens, do that.”


2️⃣ Limited Memory AI

FeatureDescription
DefinitionAI that learns from recent experiences to make better decisions.
AbilityCan store small amounts of data temporarily.
UseMost modern AI systems use this model.
ExampleSelf-driving cars, voice assistants.

🧩 Key Idea:
Limited Memory AI = “Learn from short-term experience.”


3️⃣ Theory of Mind AI

FeatureDescription
DefinitionAI that can understand human emotions, intentions, and behavior.
AbilityTries to predict human reactions and feelings.
StatusUnder research and not yet achieved.
ExampleAI with emotional understanding (like robots in movies).

🧩 Key Idea:
Theory of Mind AI = “AI that understands people.”


4️⃣ Self-Aware AI

FeatureDescription
DefinitionAI that has its own consciousness and self-awareness.
AbilityCan think, plan, and feel emotions like humans.
StatusPurely theoretical (future concept).
ExampleFictional AI — Ultron, Ava (Ex Machina).

🧩 Key Idea:
Self-Aware AI = “AI that knows it exists.”
