Cognitive systems are designed to mimic human brain processes

Like humans, cognitive systems learn as they go along. They learn from results of actions taken, and apply that knowledge when a similar situation emerges.

Unlike humans, a computer is able to use almost unlimited information and its decision-making is therefore based on a wider range of evidence.

A key feature of cognitive systems is that they come to understand their environment, and adapt as information, goals and requirements evolve.

Cognitive computing relies on machine intelligence, but with additional processes that allows it to anticipate and solve more challenging problems. These integrated features give cognitive systems the ability to cope with uncertainty that would cause problems for conventional AI systems.
