The activity vest is a wearable device that integrates multiple sensors to monitor physical activity and various health metrics. This type of wearable is designed to fit the human body, providing…

Artificial intelligence

Actor

An actor is a computational entity that encapsulates state and behavior, often used in distributed systems. In this model, each actor is independent and communicates with other actors by sending…

Artificial intelligence

Actor-Critic

The Actor-Critic approach is a type of reinforcement learning algorithm that combines two fundamental components: the 'actor' and the 'critic'. The actor is responsible for selecting actions to take…
