1-Agents

Question 1

1.what is agent? what is agent function? what is agent program?

Answer 1

Agent: A system that perceives its environment through SENSORS and act upon it though ACTUATORS.

Agent function: A function that maps perception history to actions. f: P* —-> A

Agent program: A program that runs on the physical architecture to produce f.

Question 2

2.What’s task environments? And how was it specified?

Answer 2

-Task Environment : the “problems” for which artificial agents are “solutions”

- Are specified by PEAS
P: performance measure
E: Environment
A: Acurators
S: Sensors

Question 3

3. Name some different kinds of task environment

Answer 3

There are many kinds like:

i. Fully observable vs partially observable
ii. Deterministic and stochastic
iii. Episodic and sequential
iv. Static and dynamic

Question 4

4.Diff between agent program and agent function

Answer 4

Agent program runs on a physical architecture to produce f. Using current perception as input.
Agent function is used to mapping the perception history to actions. f: P* –> A . Using history as input
