Cognitive computing means giving computers the ability to work out complex problems for themselves. Just like humans, cognitive computers benefit greatly from experience, learning better ways to solve problems with each encounter. When a traditional system of rules finds a task impossible, cognitive computing sees only an opportunity to expand its knowledge.
The necessity for cognitive computing in the Internet of Things (IoT) arises from the importance of data in modern business. In the smart IoT venues of the future, everyone from startups to enterprises to homeowners will use data to make decisions using facts rather than instincts. Cognitive computing uses data and responds to changes within it to make better decisions on the basis of specific learning from past experiences, compared with a rule-based decision system.
How we define that data is changing, though. Soon, data itself will require this level of computing to extract, making this new method even more valuable to the development of the IoT.
