According to its skills and functionalities, AI can be classified into multiple varieties. These categories help us understand the scope and applications of AI more clearly. As already we've covered a lot of ground in our recent article about Artificial Intelligence.
Now, it's time to turn our attention to types and techniques and uncover their hidden gems. The primary types of AI are:
Narrow AI, also known as Weak AI (ANI), refers to AI systems designed and trained for a specific task or a narrow set of tasks. These systems excel at their intended tasks but lack general intelligence and are unable to engage in operations outside of their domain. Virtual personal assistants such as Siri and Alexa are examples of this, as they are capable of answering inquiries and executing tasks within their programmed limitations.
General AI, which is also referred to as Strong AI (AGI), is a type of artificial intelligence that has cognitive abilities similar to humans. General AI, also known as Strong AI (AGI), represents a level of artificial intelligence that possesses human-like cognitive abilities. An AGI system has the capacity to understand, learn, and apply knowledge across a wide range of tasks, just as a human can. Achieving AGI remains a significant challenge, and currently, there are no systems that qualify as true AGI.
Artificial Superintelligence (ASI) is a hypothetical concept representing AI systems that surpass human intelligence in every aspect. ASI would possess intellectual capabilities that are not only superior to humans but also far-reaching and unfathomable. The development of ASI, if achievable, poses both immense promise and significant ethical concerns.
Narrow AI vs. General AI
Narrow AI systems, as mentioned earlier, are specialized in specific tasks. They excel in tasks like image recognition, natural language processing, and game playing but lack the ability to transfer their knowledge to unrelated domains. In contrast, General AI aims to possess a human-like ability to adapt and learn across various domains, making it a more flexible and powerful form of AI.
