Cognitive computing refers to technology that simulates human thought processes in complex situations. It combines elements of artificial intelligence, machine learning, and natural language processing to analyze data and provide insights. This technology aims to enhance decision-making and problem-solving by understanding context and learning from experiences. Systems like IBM Watson exemplify cognitive computing by processing vast amounts of information and generating human-like responses. These systems can assist in various fields, including healthcare, finance, and customer service, by offering personalized solutions and improving efficiency through advanced data analysis.
