what is AI ?
Lawan Wijerathna
AI, or artificial intelligence, refers to the simulation of human intelligence in machines that are programmed to think and learn like humans. The goal of AI is to develop systems that can perform tasks that typically require human intelligence, such as visual perception, speech recognition, decision-making, and language translation.
There are two main types of AI: narrow or weak AI, and general or strong AI. Narrow AI is designed to perform a specific task, such as facial recognition or language translation, and it operates within a limited pre-defined context. General AI, on the other hand, would have the ability to understand, learn, and apply knowledge across a wide range of tasks, similar to human intelligence. General AI is still largely theoretical and has not been achieved as of my last knowledge update in January 2022.
AI can be further categorized into three main types based on its capabilities:
Artificial Narrow Intelligence (ANI): This is the most common type of AI that is designed for a specific task. Examples include virtual personal assistants like Siri, image recognition software, and recommendation algorithms.
Artificial General Intelligence (AGI): This is a more advanced form of AI that possesses the ability to understand, learn, and apply knowledge across diverse tasks, similar to human intelligence. AGI has not been realized yet.
Artificial Superintelligence (ASI): This is a hypothetical level of AI that surpasses human intelligence across all domains and activities. It is a concept often discussed in the realm of speculative futurism and is not currently a reality.
AI can be implemented through various techniques, including machine learning, where algorithms are trained on data to improve their performance, and deep learning, a subset of machine learning that involves neural networks with many layers (deep neural networks). AI technologies are applied in a wide range of fields, such as healthcare, finance, education, transportation, and more.
