The book presents dynamics and explanatory circles on how AI systems are designed to simulate human cognitive functions, such as reasoning, problem-solving, perception, and language understanding, to varying degrees. They use algorithms and large datasets to process information and make predictions or decisions. We will be seeing that, they can perform tasks that typically require human intelligence. These tasks include things like learning from experience, understanding natural language, recognizing patterns, solving complex problems, and making decisions. In a second idea, we will look at the perspective on AI systems in the financial environment, with practical references and the approach of a business evolutionary horizon that favours the use of the tools that AI offers as a collaboration to elaborate and complement much more all the processes, adapting to the constantly changing and aggressive environment that requires diversified and powerful software and hardware tools.
