How Does AI Work?

AI systems work by processing vast amounts of data, learning from patterns, and making predictions or decisions based on this data. There are two main types of AI:

1. Narrow AI (Weak AI) – Narrow AI is designed to perform a specific task, such as identifying objects in images, recommending movies, or translating languages. This type of AI powers most of the systems we interact with today, like voice assistants (Siri, Alexa) and recommendation engines (Netflix, Amazon).
2. General AI (Strong AI) – General AI is a theoretical form of AI that would have human-like cognitive abilities. This type of AI could perform any intellectual task a human can do, but it doesn’t yet exist. Creating general AI is challenging and remains a long-term goal for researchers.

AI achieves its tasks using methods like machine learning and deep learning. Machine learning involves feeding data into algorithms, which then improve at tasks through experience. Deep learning, a subset of machine learning, uses artificial neural networks to simulate the human brain’s structure and function, making it ideal for complex tasks like image and speech recognition.
