Intelligent systems are computer-based systems that can gather, interpret, and reason about data. They are technologically advanced machines that perceive and respond to the world around them. Intelligent systems can take many forms, from autonomous cars and drones to speech and facial recognition programs to recommendation systems for online shopping. These systems have artificial intelligence that they gain after training on lots of data, using a variety of computational models.

Intelligent systems are designed to solve complex problems automatically and more efficiently within specific environments. They are formed by the collaboration of people and technologies such as Big Data, the IoT, and sensors. The field of intelligent systems also focuses on how these systems interact with human users in changing and dynamic physical and social environments.

Intelligent systems have fundamental properties such as perception, action control, interaction or connectivity, remote management, user experience, and data analytics. They possess cognitive capabilities such as perception, action control, deliberative reasoning or language, follow principles of behavior based on rationality and social norms, and have the ability to adapt by learning.

In summary, intelligent systems are computer-based systems that can gather, interpret, and reason about data. They have artificial intelligence and are designed to solve complex problems automatically and more efficiently within specific environments. They possess cognitive capabilities and fundamental properties such as perception, action control, interaction or connectivity, remote management, user experience, and data analytics.
