Self-Aware AI	Theoretical AI that would have consciousness and self-awareness, similar to humans.	Not yet developed
Narrow AI	AI designed for specific tasks without general intelligence.	Siri, Alexa, ChatGPT, Edcafe AI, image recognition, fraud detection
General AI	Hypothetical AI with human-like reasoning and problem-solving across various tasks.	Not yet developed
Superintelligent AI	AI that surpasses human intelligence in all areas, including creativity and reasoning.	Not yet developed (theoretical concept)

Algorithm

Algorithm is commonly confused with AI, but they are closely related. An algorithm serves as the backbone of AI by providing the instructions that AI must follow. Without it, AI wouldn’t exist. Among the common examples of algorithms are classification, regression, and clustering. An algorithm is used in various contexts such as mathematics, computer science, or real life. Whenever you make your hot coffee or follow your daily routine, it counts as an algorithm.

Dr. Mir Emad Mousavi, founder and CEO of QuiGig, notes the main difference between AI and algorithm: “…an algorithm defines the process through which a decision is made, and AI uses training data to make such a decision. For example, you can collect data from thousands of driving hours by various drivers and train AI about how to drive a car. Or you can just code it [to say] when [it] identifies an obstacle on the road it pushes the break, [or] when it sees a speed sign, [it] complies. So with an algorithm, you are [setting] the criteria for actions.”
