Cognitive Computing
Computer systems designed to mimic human thought processes and cognitive functions for complex problem-solving.
What is Cognitive Computing?
Cognitive computing refers to computer systems designed to simulate human thought processes and cognitive functions. These systems aim to create machines that can reason, learn, perceive, and interact in ways that mimic human cognition, enabling them to solve complex problems that typically require human intelligence.
