- Weak AI systems are proficient in the tasks they are designed for but lack the broad spectrum of cognitive abilities and self-awareness found in human intelligence.
2. Strong AI (General AI or AGI – Artificial General Intelligence)
- Strong AI, on the other hand, refers to AI systems or machines with generalized human cognitive abilities. These systems possess intelligence and consciousness comparable to that of human beings, allowing them to understand, learn, reason, and solve problems across various domains and contexts.
- Strong AI aims to mimic human-like intelligence comprehensively, including the ability to apply knowledge and skills from one domain to another, exhibit self-awareness, and learn in a manner akin to human learning.
- Achieving Strong AI remains an aspirational goal in AI research, as current AI systems are primarily Weak AI and have not achieved true general intelligence or consciousness.
Types of Artificial Intelligence
The classification of Artificial Intelligence (AI) into different types is often based on their capabilities and functionalities. The categorization includes:
1. Purely Reactive AI
These AI systems operate in the present moment and make decisions based solely on current data without any memory or past experiences. They do not have the ability to retain or use historical data for decision-making. For example, in a game of chess, a purely reactive AI evaluates the current board position and makes the best move based on that specific scenario.
2. Limited Memory AI
Unlike purely reactive systems, AI with limited memory retains some past data or experiences to improve decision-making. These systems store a certain amount of historical data to enhance their understanding or predictions. For instance, recommendation systems using limited memory AI consider past user preferences to suggest movies, restaurants, or products.
3. Theory of Mind AI
This hypothetical type of AI remains under development and aims to comprehend human emotions, thoughts, and social interactions. A machine with the theory of mind could understand human intentions, beliefs, and emotions, allowing it to interact more convincingly in social settings. However, this kind of AI is yet to be realized.
4. Self-Aware AI
This category represents an AI system that possesses consciousness, self-awareness, and human-like intelligence. Self-aware AI would not only understand its environment but also recognize its own existence, emotions, and thoughts. Currently, this type of AI remains theoretical and is a subject of philosophical and ethical discussions rather than a realized technological development.
It’s important to note that while the first two types, purely reactive and limited memory AI, are currently in use, theory of mind and self-aware AI remain largely conceptual and theoretical. The latter two types pose significant challenges and raise ethical considerations that extend beyond the realm of technology and delve into philosophical and existential questions about consciousness and the nature of intelligence.
