Deep Learning for Autonomous Systems

Deep Learning is a subfield of machine learning that focuses on algorithms inspired by the structure and function of the brain called artificial neural networks. These neural networks consist of interconnected nodes, or artificial neurons, that process information in layers. Deep learning has gained popularity due to its ability to automatically learn representations from data, leading to state-of-the-art performance in various tasks such as image recognition, speech recognition, natural language processing, and autonomous systems.

Autonomous Systems refer to machines or systems that can perform tasks without human intervention. These systems use sensors, actuators, and artificial intelligence to perceive their environment, make decisions, and act accordingly. In the context of military defense, autonomous systems can include unmanned aerial vehicles (UAVs), autonomous ground vehicles, and autonomous underwater vehicles (AUVs) that can operate in dangerous or remote environments.
