Flashcards

Static Environment

An environment is considered static if it does not change over time while the agent is operating. This means the agent doesn't need to adapt to new situations or conditions.

What does 'S' stand for in PEAS?

The 'S' in PEAS refers to 'Sensors'. Sensors are the components of an agent that allow it to perceive the environment and gather information about its current state.

What kind of environment is a flight simulator?

An artificial environment is one that is created by humans, such as a computer simulation or a video game. However, some artificial environments can be very complex and challenging for agents to navigate.

What does 'PEAS' Stand for?

PEAS stands for Performance, Environment, Actuators, Sensors. These four components are essential for defining and designing any rational or intelligent agent.

What defines an autonomous agent?

An autonomous agent can make its own decisions and actions based on its internal mechanisms and past experiences. It doesn't rely solely on external instructions. It can learn and adapt to new situations.

Key difference between softbots and physical agents?

Software agents operate in virtual or artificial environments, unlike physical agents that interact with the real world. This means their actions are limited to the digital world.

Main characteristic of an intelligent agent?

The primary characteristic of an intelligent agent lies in its ability to perceive its environment through sensors and take actions through actuators. This loop of perception and action is crucial for intelligent behavior.

What is NOT part of PEAS?

Rewards are not part of the PEAS framework for defining agents. PEAS focuses on Performance, Environment, Actuators, and Sensors.

What can a vacuum-cleaner agent perceive?

A vacuum cleaner agent's sensors can detect the location of the agent within the environment and whether the space is clean or dirty. These are the inputs that guide the agent's actions.

Actions a vacuum cleaner agent can perform?

A vacuum cleaner agent can perform actions like moving left, moving right, and sucking up dirt. These actions are the agent's way of interacting with its environment.

What is a rational agent?

A rational agent acts in a way that maximizes its performance measure. Ideally, this means making choices that lead to the best possible outcomes based on its goals and the environment.

Relationship between agent's architecture and program?

An agent's program is the software implementation of its architecture. It defines how the agent takes in input, processes information, and generates output (actions).

Purpose of a performance measure?

The primary purpose of a performance measure in the context of an agent is to evaluate how well the agent is achieving its goals within the environment. It acts as a metric to judge the agent's success.

Factor NOT determining an agent's rationality?

Computational resources are not a defining factor for an agent's rationality at a given time. Rationality is primarily determined by the agent's knowledge, goals, and the environment.

What are actuators?

Actuators represent the actions an agent can perform to interact with the world. These are the agent's tools to manipulate the environment.

What is NOT a performance measure for a vacuum cleaner agent?

The agent's ability to navigate through obstacles is not directly a performance measure for a vacuum cleaner agent. Its performance is typically judged by how clean the floor becomes.

What is the percept sequence in an exam scenario?

In an exam scenario, the percept sequence for a rational agent would be the combination of the questions on the exam paper and the agent's prior knowledge. This represents all the information available to the agent.
