Answer 8

making choices when not all of the information is available

Question 9

when were first artificial neurons developed?

Answer 9

1950s but didn’t have all to train them that didn’t come till 60s

Question 10

agent

Answer 10

entity with a set of sensors (data) and actuators (actions) which operates in an environment

Question 11

agent function

Answer 11

maps percepts to actions

Question 12

agent environment

Answer 12

external system which agent operates in

Question 13

5 types of environments and definitions

Answer 13

deterministic (next state is determined by current state, no element of chance involved) vs stochastic (deals with probability)
episodic (next episode doesn’t depend on previous episodes actions) vs sequential (current actions affect future)
offline (all data available for training) vs online
discrete vs continuous (inf # states and actions)
single vs multi agent

Question 14

perceptron

Answer 14

sensors that are means of agent to perceive environments

Question 15

action

Answer 15

any process that changes environment

Question 16

reflex agent

Answer 16

selects actions based solely on current percepts not history
don’t maintain states

Question 17

model agent

Answer 17

maintains internal state that can reference and update and keeps a history of what came before

Question 18

goal agent

Answer 18

search for a way to achieve a specific goal

Question 19

utility agent

Answer 19

internalise performance measured through utility function with goal to maximise utility of its actions

Question 20

learning agent

Answer 20

uses some form of feedback to improve over time
