Smart agent.

1. What is an intelligent agent?

   • An agent is an entity that perceives and acts on its environment
   • We can define the intelligent agent as a software entity that, based on its own knowledge, performs a set of operations aimed at satisfying the needs of a user or another program, either on its own initiative or because one of these requires it.

2. How is an intelligent agent different from a conventional software model?

   • The intelligence dimension refers to the degree to which the application uses reasoning, learning and other techniques to interpret the information or knowledge to which it has access.
   • Agency is the degree to which the agent can perceive his environment and act on it. It defines the agent, in other words, for a program to be an agent it must possess autonomy, social ability, re-activity and pro-activity.

3. What model of intelligent agents exist?

   • reactive agents
     • These agents select actions based on the current perceptions, ignoring the rest of the perceptions historical.
   • Simple reactive agents
     • Infinite loops are often unavoidable for agents simple reagents that operate in some environments partially observable.
   • Model-based reactive agents
     • The most effective way for officers to handle partial visibility is storing information about parts of the world that they cannot see. Or what is the same, the agent must maintain some kind of internal state that depends on the perceived history and that in this way reflects at least some of the aspects not observables of the current state.
   • Model-based reactive agents
     • This knowledge about << how the world works >>, whether is implemented with a simple boolean circuit or with theories complete scientific studies, it is called a model of the world. An agent that uses this model is a model-based agent.
   • Model-based reactive agents
     • Knowledge about the current state of the world is not always enough to decide what to do. For example, at a junction of roads, the taxi driver can turn left, turn right or keep going. The right decision depends on where you want to go the taxi.

4. What are smart agents for?

   • It is an entity capable of perceiving its environment, processing such perceptions and responding or acting in its environment in a rational way, that is, in a correct way and tending to maximize an expected result. It is capable to perceive their environment with the help of sensors and act in that medium using actuators (elements that react to a stimulus performing an action).

5. The state of the art regarding intelligent agents.

   • These systems are levers of the development of the companies that the use, so that beyond just providing information on how make decisions, allow the development of new products, reinforce sales, facilitate plant operation, and ultimately facilitate the increase in productivity and performance of companies.

6. Real applications of intelligent agents.

   • Voice assistants
     • These assistants, who use language processing (PLN) to interpret the voice commands and responding to them, you allow you to play music with a order, they remind you to throw the trash or that you read to your children a story of good evening.
   • Smartphones
     • Smartphones use AI from many ways so sure you use it a few times a day with just one finger. Siri and the Assistant from Google are already functions known from mobile phones that allow you to search and voice requests.

7. EXAMPLES:

   • NETFLIX
     • Recommendation agents: they have as mission to make recommendations to users of products that might interest them, based on their profile and knowledge of the business context.
   • Ebay
     • Trading agents: they intend to transfer to the electronic market the negotiation processes that normally occur when carrying out a business transaction. For which there are purchasing agents and sellers who collaborate to reach an agreement on the conditions purchase of a product.
