Artificial intelligence

(also AI)

Artificial intelligence definition

Artificial intelligence (AI) is the simulation of human intelligence by machines, most commonly computers. Artificial intelligence is used in many areas, including expert systems, language processing, machine vision, speech recognition, and cybersecurity. AI absorbs large amounts of training information, analyzes it for patterns and correlations, then uses these patterns to create similar outputs.

How artificial intelligence works

Artificial intelligence programming relies on three skills:

  • Learning. AI programming acquires data and creates algorithms for turning the data into actionable information. These algorithms provide step-by-step instructions to devices for completing a specific task.
  • Reasoning. Artificial intelligence programming focuses on selecting the right algorithm to produce the desired result.
  • Self-correction. AI programming continually fine-tunes its algorithms to ensure they produce the most accurate results.

Four types of artificial intelligence

  • Reactive machines. Reactive AI can’t form memories or use past experiences to make decisions.
  • Limited memory. These machines can look into the past for previous data to make better predictions.
  • Theory of mind. These types of AI machines are still in the beginning phase. The theory of mind machines can interact with the emotions and thoughts of humans.
  • Self-awareness. Self-aware AI machines are also yet to come. They will be able to form representations of themselves and have consciousness.
