Lecture 3 Building Rational Agents Pdf Cognitive Science Cognition Introduction: environments and problem solving methods. many areas of ai are essentially characterized by the properties of environments they consider and which of the three problem solving approaches they use. beyond the course (“advanced topics”). The agent function describes what the agent does in all circumstances the performance measure evaluates the environment sequence a perfectly rational agent maximizes expected performance agent programs implement (some) agent functions peas descriptions define task environments environments are categorized along several dimensions:.
Rational Agents Environments Pdf • in an episodic task environment, the agent’s experience is divided into atomic episodes. in each episode the agent receives a percept and then performs a single action. What makes an agent good or bad, intelligent or stupid? agents and environments. 4. • a rational agent is one that does the right thing. • right thing: the agent’s actions causes the environment to go through a sequence of states. if the sequence is desirable, then the agent has performed well. For each possible percept sequence, a rational agent should select an action that is expected to maximize its performance measure, given the evidence provided by the percept sequence and whatever built in knowledge the agent has. We give a crude categorization of environments and show how properties of an environment influence the design of suitable agents for that environment. we describe a number of basic “skeleton” agent designs, which will be fleshed out in the rest of the book.

Rationality does not mean an agent is omniscient or clairvoyant, so rational agents must explore, learn, and act autonomously to gather information and compensate for limitations. “in which we discuss the nature of agents, perfect or otherwise, the diversity of environments, and the resulting menagerie of agent types.” reading: aima, ch. 2 1. agents, environments and rationality. Task environments or problem environments are the environments, which include all the elements involved in the problems for which agents are thought of as solutions. Ideally, the incorporation of learning allows for the design of a single rational agent that will succeed in a variety of different environments and for a variety of tasks (the goal of agi).
