Artificial Intelligence(AI) section2 1) What is agent? 2) Applications of agent in different fields? 3) Vacuum_cleaner agent? 4) Rational agent ,, agent ? 5) Variables in python ? 1) What is agent ? Agent : is anything that senses environment using sensors and act upon that environment through its actuators. sensor: is the part that receives input from the environment. actuators: is the part that helps interact with the environment. percept: we use the term perception to refer to an agent's perceptual input at any given moment. percept sequence: agent's percept sequence is the complete history of everything the agent has ever perceived. agent function(control policy function): is a set of condition-rules based on it the agent can make decision"action". 2) Applications of agent in different fields ? 3) Vacuum_cleaner agent ? 4) performance measure,,Rational agent ? Performance measure: An objective criterion (“utility function”) for success of an agent's behavior. Performance measures of a vacuum-cleaner agent: amount of dirt cleaned up, amount of time taken, amount of electricity consumed, level of noise generated, etc. Performance measures self-driving car: time to reach destination (minimize), safety, predictability of behavior for other agents, reliability, etc. Performance measure of game-playing agent: win/loss percentage (maximize), robustness, unpredictability (to “confuse” opponent), etc. Rational Agent: For each possible percept sequence, a rational agent should select an action that maximizes its performance measure (in expectation)given the evidence provided by the percept sequence and whatever built in knowledge the agent has. rationality: do the right thing. -maximize expected performance -information gathering,exploration,learning. ---------------------------------------------------------------------- ---------------------------------------------------------------------- ---- 5) variables in python ? some important information:- Run == F5 space in the first of line "error" python is case sensitive types of variables:- · string,float,integer,boolean,complex,list,tuple, set,dictionary 5.1) number variables(integer,float):- - to define number variable - to convert from datatype to another - arithmatic operation on number variable :- - math library :- is a set of methods that you can invoke them in arithmatic operations 5.2) string variable:- - to define string variable - to access any character in string,last index is not included - to repeat string or character in string - to split string ,depending on certain symbols,symbols "deleted" split - to split string depending on certain symbols ,symbols "included" partition,must contain argument - to search for word or character in string find,return index of word or character if character not found return -1 - to return index througth character,index,if character not found return error - to replace character with another,replace - To find out how many times a letter or character is repeated,count - to display all characters capital upper - to display all character small lower - to diplay the first character of statement capital capitalize - to traverse the state of character swapCase - to display the first character from each word capital title 5.3) boolean variable:-
