How to Learn Artificial Intelligence?

Machines and computer systems that simulate human intellect to carry out activities like problem-solving, decision-making, and experience-based learning are referred to as artificial intelligence (AI). Algorithms and data are used by AI systems to evaluate information and gradually enhance their performance, which make the Artifical intelligence of one the best technology in the human kind.

Some examples of AI in action:

• Virtual assistants like Siri, Alexa, and Google Assistant
• Recommendation systems on Netflix, YouTube, and Amazon
• Self-driving cars powered by AI algorithms
• AI-powered chatbots used by businesses for customer support

AI is a broad field that includes several subfields like Machine Learning (ML), Deep Learning (DL), and Data Science.

What are the Different Types of Artificial Intelligence?

AI is generally classified into three types based on capabilities and four types based on functionality.

Types of AI Based on Capabilities

1. Narrow AI (Weak AI) – AI designed for a specific task, such as voice assistants or spam filters.
2. General AI (Strong AI) – AI that can perform any intellectual task that a human can do (this is still in research).
3. Super AI – Hypothetical AI that surpasses human intelligence, is capable of self-awareness and reasoning (not yet developed).

Types of AI Based on Functionality

1. Reactive Machines – AI that operates based on predefined rules (e.g., IBM’s Deep Blue chess-playing AI).
2. Limited Memory AI – AI that can learn from past experiences (e.g., self-driving cars).
3. Theory of Mind AI – Future AI that will understand human emotions and behaviours.
4. Self-Aware AI – Theoretical AI that will possess human-like consciousness.
